There are two types of reproduction – asexual and sexual. The process of fusion of sperm with egg (ovum) to produce zygote is called fertilization. Infants rely on their caregivers for comfort, cleanliness, and food. Google Classroom Facebook Twitter. Female reproductive system. 15 lessons in Reproduction and variation: Human Reproductive System; Fertilisation; Gestation; For example, the male's major sex hormone, testosterone, which is actually produced in the testes, is responsible for many masculine traits. Only one sperm is required to fertilize the ovum. In both sexes the gonads go on to form the testes and ovaries; because they are derived from the same undeveloped structure, they are considered homologous organs. The major function of the reproductive system is to ensure survival of the species. The female reproductive system in humans plays a significant role in the production of ova, fertilization, implantation, and gestation. During puberty, eggs in the ovaries start to mature. It is one of the fundamental characteristics of living things and an essential life process. Humans have a high level of sexual differentiation. Click ‘Start Quiz’ to begin! Sperms are small unicellular structures with a head, middle piece, and a tail. Major secondary sexual characteristics include: larger, more muscular stature, deepened voice, facial and body hair, broad shoulders, and development of an Adam's apple. Hence, the newly formed individual will be different from parents, both genetically and physically. During this fundamental process, both male and female reproductive organs play an important role. The male reproductive system The male reproductive organs are the penis, the testicles, the epididymis, the vas deferens and the prostate gland: Penis – contains tissue that fills with blood during sexual arousal, making the penis erect (or ‘hard’). The human reproductive system is different in males and females. Reproductive System Disease. The reproductive system is made up of a group of sexual organs that mark the physical difference between males and females. The female reproductive system is designed to carry out several functions.

In females, gametogenesis is known as oogenesis; this occurs in the ovarian follicles of the ovaries. The final category are those used for copulation and deposition of the sperm within the female; these include the penis, urethra, and vas deferens. When a sperm and egg join, the egg is fertilised and a baby starts to develop. The major reproductive organs of the male can be grouped into three categories. They are responsible for the... Scrotum: It is a sac-like organ that hangs below the penis and behind it. These are produced in the testes, which are housed in the temperature-regulating scrotum; immature sperm then travel to the epididymis for development and storage. They involve specialized and different anatomies in the two sexes, a hormone regulation system, and specialized behaviors regulated by the brain and endocrine system. Urethra. Human Reproductive System. 1. Very helpful and wanted information. The reverse is true for the Müllerian duct, as it essentially disappears in the male reproductive system and forms the Fallopian tubes, uterus, and vagina in the female system. Human Reproductive Anatomy The reproductive tissues of male and female humans develop similarly in utero until about the seventh week of gestation when a low level of the hormone testosterone is released from the gonads … Approximately every 28 days, the pituitary gland releases a hormone that stimulates some of the ova to develop and grow. Test your Knowledge on Human Reproductive System! An important sexual hormone of males is androgen, and particularly testosterone. Human Reproductive System Gamete Production. The human female reproductive system is a series of organs primarily located inside the body and around the pelvic region of a female that contribute towards the reproductive process. This period is divided into three stages, which are collectively called trimesters. Human reproduction normally begins with copulation, followed by nine months of pregnancy before childbirth, though it may be achieved through artificial insemination. Other systems in the body, such as the endocrine and urinary systems, work continuously to maintain homeostasis for survival of the individual. There are four main categories of reproductive diseases in humans. our reproductive systems we refer to them as our sex hormones. Many congenital conditions cause reproductive abnormalities, but are better known for their other symptoms. Asexual mode reproduction occurs only in lower invertebrates and other simpler living species such as amoeba, bacteria, and hydra. Email. The human Reproductive System Both sexes have reproductive organs called GENITALS or GENITALIA designed for the purpose of intercourse and conception. Food may be provided by breastfeeding or formula feeding.[1]. [3] However, recent scientific research has challenged that hypothesis. Female reproductive organs are for intercourse, reproduction, urination pregnancy and childbirth. These include: Turner syndrome, Klinefelter's syndrome, Cystic fibrosis, and Bloom syndrome. A complete pregnancy period lasts for 38-40 weeks or 9 months from the first day of your last menstrual period to the birth of the baby. In this process, two parents are involved in producing a new individual. Human Reproductive System Displaying top 8 worksheets found for - Human Reproductive System . Reproduction is the process of producing new individuals of the same species by existing organisms of a species that is parents. Learn more about reproduction in human beings, its types, process, significance  and other related topics at BYJU’S Biology. The reproduction in human beings involves the fusion of male and female gametes produced in their reproductive system. The reproductive system. It consists of the following parts: Female reproductive system has two functions –. Like all complex organ systems, the human reproductive system is affected by many diseases. The fertilized egg is called the zygote. If the ovum is fertilized by sperm, it attaches to the endometrium and the fetus develops. The sperm then travels through the vagina and cervix into the uterus or fallopian tubes for fertilization of the ovum. The male reproductive system is different from the female reproductive system, both in structure and in function. The breasts are involved during the parenting stage of reproduction, but in most classifications they are not considered to be part of the female reproductive system. Human reproduction is an example of sexual reproduction. Gametes are produced by a two-part cell division process called meiosis. When the fetus has developed to a certain point, pregnancy is concluded with childbirth, involving labor. This lesson introduces the gametes and the male and female reproductive systems. Despite the differences between the adult female and male are derived from the intermediate mesoderm. Your email address will not be published. Since the scrotum, where the testes is present, is situated outside the body cavity, it provides a temperature about 3 °C below normal body temperature. Reproduction can be defined as the biological process of producing a new individual or an offspring identical to the parents. Some of the worksheets for this concept are Human female reproductive system cloze work, Chapter 13 the human reproductive system, Biology 12, Grades 6 to 8 human body series female reproductive system, Students work docs, Name reproductive system work, Reproductive system, Puberty and … The development of the reproductive system and the development of the urinary system are closely tied in with the development of the human fetus. Zygote starts to divide into many cells and develops into an embryo. Semen is a mixture of sperm and fluid from the male reproductive organs. The vagina meets the outside at the vulva, which also includes the labia, clitoris and urethra; during intercourse this area is lubricated by mucus secreted by the Bartholin's glands. Pregnancy can be avoided with the use of contraceptives such as condoms and Intrauterine devices. Many years of parental care are required before a human child becomes independent, typically between twelve and eighteen or more. normally remain slightly cooler than body temperature to facilitate sperm production Embryo moves into the uterus and gets attached to its walls. This process ensures the increase in the number of individuals of a species when conditions are favourable. However, despite the similarity in function of the female Fallopian tubes and the male epididymis and vas deferens, they are not homologous but rather analogous structures as they arise from different fetal structures. A significant proportion of the human male reproductive system is external, composed of the penis, scrotum and testicles. Role of different structures within male and female reproductive system Female reproductive system Ovaries Ovaries are considered as the primary organs of the reproductive system. A small proportion of the sperm pass through the cervix into the uterus, and then into the Fallopian tubes for fertilization of the ovum. The male gametes, i.e., sperms are produced within the male reproductive system. Both sexual and asexual are two different modes of reproduction. In human beings, both males and females have different reproductive systems; hence, they are known to exhibit sexual dimorphism. Reproduction is a fundamental biological process carried out by different living organisms to produce their young ones or offspring. In Biology, the trimester system mainly refers to three months. Human infants are completely dependent on their caregivers, and require high levels of parental care. The male reproductive system consists of : The female reproductive system is active before, during and after fertilization as well. The process of reproduction in humans usually begins with copulation, followed by the Pre-fertilization, Fertilization, and Post-fertilization. Asexual reproduction takes place in small organisms like hydra, amoeba, paramecium, etc. Genetic Conditions > Reproductive system. The male reproductive system is a series of organs located outside the body and around the pelvis region of a male that contribute towards the reproduction process. That’s right, in this one we’ll be testing your knowledge on both the male and female reproductive systems to find out just how much you know about human reproduction! The major reproductive organs of the male can be grouped into three categories. Human reproductive system, organ system by which humans reproduce and bear live offspring. The human reproductive system includes the male reproductive system which functions to produce and deposit sperm; and the female reproductive system which functions to produce egg cells, and to protect and nourish the fetus until birth. Hormones produced by the ovaries prepare the uterus to receive the ovum. The testes release a hormone that controls the development of sperm. Asexual Reproduction — This process of reproduction involves only one parent and the new offspring produced is genetically similar to the parent. The human female reproductive system is a series of organs primarily located inside the body and around the pelvic region of a female that contribute towards the reproductive process. Parturition is the process of delivering the baby after the completion of pregnancy or a fully grown developed fetus and placenta from the uterus to the vagina to the outside world. Male Reproductive System. Stage 1: Preparatory Stage- 2 to 12 hours. Human reproduction begins when sperm from the male fertilizes an egg from the female. It may be asexual or sexual reproduction. Production of female gamete called ovum/egg. The male reproductive system consists of : Testicles (testes): A pair of oval-shaped organs masked in a pouch called the scrotum. Examples of unclassifiable disorders are Peyronie's disease in males and endometriosis in females. The second category are the ejaculatory fluid producing glands which include the Cowper's gland (also called bulbo-urethral gland), seminal vesicles, prostate, and vas deferens. Gametes are produced within the gonads through a process known as gametogenesis. In addition to differences in nearly every reproductive organ, there are numerous differences in typical secondary sex characteristics. Thank you byjus. The production and survival of sperms require a temperature below the normal core body temperature. It produces the female egg cells necessary for reproduction, called the ova or oocytes. This marks the beginning of gestation, better known as pregnancy, which continues for around nine months as the fetus develops. The vagina is attached to the uterus through the cervix, while the uterus is attached to the ovaries via the Fallopian tubes. The reproductive system. Human Reproductive System. Introduction to the Reproductive System. The Human Reproductive System The Human Reproductive System Interactive Worksheet ID: 1119333 Language: English School subject: Science Grade/level: 6 Age: 11-12 Main content: Human body systems Other contents: reproductive system Add to my workbooks (14) Download file pdf One ovum is released and it passes through the Fallopian tube into the uterus. The human male reproductive system is a series of organs located outside of the body and around the pelvic region. Stage 3: Placenta Expulsion –1 to 12 hours. The reproductive system is susceptible to a number of diseases … Female Reproductive System Physiology The Reproductive Cycle. [4] This new research indicates that in at least some species of mammal, oocytes continue to be replenished in females well after birth.[5]. During this process, the male inserts his erect penis into the female's vagina and ejaculates semen, which contains sperm. These secretes two of the very essential hormones which are important for a female body in the whole process of the reproduction (Agarwal and et.al, 2012). In contrast with males, each of the original diploid germ cells or primary oocytes will form only one mature ovum, and three polar bodies which are not capable of fertilization. Worksheet. https://en.wikipedia.org/w/index.php?title=Human_reproductive_system&oldid=998947399, Wikipedia articles needing clarification from July 2018, Creative Commons Attribution-ShareAlike License, This page was last edited on 7 January 2021, at 19:39. The male gametes, i.e., sperms are produced within the male reproductive system. The human reproductive system includes the male reproductive system which functions to produce and deposit sperm; and the female reproductive system which functions to produce egg cells, and to protect and nourish the fetus until birth. Presentation. Such as body hair, the deepening of your voice, muscle growth, and there's [6], EDRI Federal Project Inventory: Cellular and Molecular Mechanisms of Abnormal Reproductive Development, "The Current Status of Evidence for and Against Postnatal Oogenesis in Mammals: A Case of Ovarian Optimism Versus Pessimism?". Lesson overview: Human Reproductive System View in classroom. Exit Quiz. In human, reproduction plays a significant role in the continuity of species from one generation to another generation. Combined with the cardiovascular system, the circulatory system helps to fight off disease, helps the body maintain a normal body temperature, and… READ MORE Male Reproductive Without reproduction, there would no life existing on the planet earth. The reproductive system review. The female reproductive cycle is the process of producing an ovum and readying the uterus to receive a fertilized ovum to begin pregnancy. This occurs when certain types of germ cells undergo meiosis to split the normal diploid number of chromosomes (n=46) into haploid cells containing only 23 chromosomes.[3]. This process does not produce mature ovum until puberty. Each ovary contains hundreds of egg cells or ova (singular ovum). All human beings undergo a sexual mode of reproduction. human nervous system: The reproductive system The sexual response in both males and females can be defined by three physiological events. The Wolffian duct forms the epididymis, vas deferens, ductus deferens, ejaculatory duct, and seminal vesicle in the male reproductive system, but essentially disappears in the female reproductive system. Lecture for students about Human reproductive system Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. Endocrine hormones are a well-known and critical controlling factor in the normal differentiation of the reproductive system.[2]. Cell Differentiation is the process through which a young and immature cell develops into a specialized and matured cell. This process occurs in three stages, which includes: Humans reproduce their young ones sexually by the interaction between the male and female reproductive organs. Sexual mode reproduction takes place in all multicellular organisms including humans, animals, and higher plants. Welcome to the reproductive system. In this process, the male inserts his penis into the female's vagina and ejaculates semen, which contains sperm. Fertilization is a crucial stage of reproduction in human beings. The human reproductive system usually involves internal fertilization by sexual intercourse. This is … If an ovum is produced but not fertilized and implanted in the uterine wall, the reproductive cycle resets itself through menstruation. Males have testes- also called testicles, while the females have a pair of ovaries. [clarification needed][no main verb] The three main fetal precursors of the reproductive organs are the Wolffian duct, the Müllerian ducts, and the gonads. The primary direct function of the male reproductive system is to provide the male sperm for fertilization of the ovum. There are a number of other homologous structures shared between male and female reproductive systems. The first category produces and stores sperm (spermatozoa). This hormone is also responsible for the development of physical characteristics in men such as facial hair and a deep voice. It has long been understood that in females, unlike males, all of the primary oocytes ever found in a female will be created prior to birth, and that the final stages of ova production will then not resume until puberty. One of the ovaries releases the matured ovum in every 28 to 30 days and is called ovulation. The seminal vesicles are two structures, about 5 cm (2 inches) in length, lying … Video. The immature spermatozoa or sperm are then sent to the epididymis, where they gain a tail, enabling motility. During labor, the muscles of the uterus contract and the cervix dilates over the course of hours, and the baby passes out of the vagina.

Sexual Reproduction –This process of reproduction is very complex that involves the formation and transfer of gametes, followed by fertilization, the formation of the zygote, and embryogenesis. Human reproduction usually involves internal fertilization by sexual intercourse. Each of the original diploid germ cells or primary spermatocytes forms four functional gametes which is each forever young[clarification needed].
