...The reproductive system or genital system is a system of organs within an organism which work together for the purpose of reproduction. Many non-living substances such as fluids, hormones, and pheromones are also important accessories to the reproductive system. Unlike most organ systems, the sexes of differentiated species often have significant differences. These differences allow for a combination of genetic material between two individuals, which allows for the possibility of greater genetic fitness of the offspring. The major organs of the reproductive system includes, the external genitalia as well as a number of internal organs including the gamete producing gonads . Diseases of the human reproductive system are very common and widespread, particularly communicable sexually transmitted diseases. Most other vertebrate animals have generally similar reproductive systems consisting of gonads, ducts, and openings. However, there is a great diversity of physical adaptations as well as reproductive strategies in every group of vertebrates. Human reproductive system Human reproduction takes place as internal fertilization by sexual intercourse. During this process, the erect penis of the male is inserted into the female's vagina until the male ejaculates semen, which contains sperm, into the female's vagina. The sperm then travels through the vagina and cervix into the uterus or fallopian tubes for fertilization of the ovum. Upon successful fertilization and implantation...

Male Reproduction What it Does Good and Bad 04. Fertilization 05. References Human Reproduction System Hi, my name is Sary Metellus and I am doing an essay on the Human Reproductive System, Male and Female. “All living things reproduce.” (Steven Dowshen, Femal Reproductive System, 2010) That’s a pretty interesting saying. Both male and female reproductions are very important to produce a new individual – a child, baby. Now I’m writing about the female system like the organs unlike the males which are hung out, the females are inside the body. The female’s internal reproductive organs are the vagina, uterus, fallopian tubes, and ovaries. The vagina is the inside the body which is connected to the vulva and that is the outside covering. It’s a muscular hollow tube, which connects the opening to the uterus. It’s muscular so it can contract and expand, which helps with delivering a baby or using a tampon. The cervix is the neck, which has strong thick walls, and it is the opening to the uterus. The uterus is shaped like an upside-down pear and is very strong, it is the part where it will hold the baby and grow the baby in it. The uterus is connected to the fallopian tube which connects to the ovaries. There are two oval-shaped ovaries, one on each side of the...

...In this assignment I am going to be outlining all the gross structures of the main body systems and I would also be saying what the system is made out of with a diagram. Main body system • Skeletal System • Muscular System • Nervous system • Respiratory system • Digestive System • Male Reproductive System • Female Reproductive system • Cardiovascular system • Urinary system • Endocrine system 1. Skeletal system The skeletal system is muscle that is connected to the skeletal to make a part of the mechanical system which moves the limbs and other parts of the body. The skeletal also relates the cartilages and joints of the human body which then creates the human skeleton. It is one of the main and important systems in the body. The joints are very important because they allow different types of movements at different locations to happen. However there are three components; • Bones • Cartilages • Joints Bones: Bones is a tough and frim form of connective tissue. It is the responsibility is to almost all strength of skeletal. Bone is the mineralization factor. Bones are highly mineralized with calcium salts Cartilages: The cartilage is a form of the connective tissue however it is not as tough and frim as the bone and the main difference in the cartilage and bone is the mineralization factor. This is because the bones are highly mineralized with calcium salts whereas cartilages are not. Joints: the joints are important components of the human body...

...with alteration of their heads. The liquid portion of the semen also provides directions for the sperm so they will not wander too far off the path. Any sperm that has not successfully made it thru the cervix is not going to make the complete journey and will release out of the Nancy body after the sex act. For the sperm that make it thru the cervical canal it is greatly welcomed environment the sperm will find that there is an abundance of cervical mucus, the mucus will transport the sperm when you are in your more productive state. As Nancy move toward ovulation her copious mucus becomes clear, stretchy and also thin. This process help the sperm arrive to their destination. The sperm can only live for 2-3 days with in the Nancy reproductive system. John’s sperm only has 12-24 hours to fertilize her egg. Once Nancy egg is fertilized it undergoes several diversions to form a...

...Reproductive System Reproduction- Is the process by which new living organisms are produced from existing living organisms. The Male Reproductive System The Parts of the male reproductive system are: 1.Testes/Testicles-produces the male sex cells. (sperm cells) 2.Epididymis-stores the sperms produced by the testes. 3.Scrotum/Scrotal Sac-is the skin that protects the testes. -it holds the testicles. 4.Penis-is the part of the organ that hangs in front of the scrotum. -it deposits the sperm cells into the vagina. 5.Urethra-is a tube where the sperm and the urine pass through. 6.Vas Deferens-where the sperms travel. 7.Prostate Gland-The prostate is a walnut-sized gland located between the bladder and the penis. Female Reproductive System 1.Fallopian Tube-It is where the egg cell travels from the ovary and where fertilization takes place. 2.Ovaries-produces thousand of eggs. 3.Uterus-It is where the fetus develops into a baby. 4.Fimbriae-fringe of tissue around the Fallopian tube in the direction of the ovary. 5.Cervix-It stretches open wide enough for the baby to pass through during delivery. 6.Vagina-It is an elastic vascular muscle of female reproductive Organ that expands during giving birth. *The Male Hormones(Testosterone) *The Female Hormones(Estrogen and Progesterone) *The Male Reproductive System is designed for the reproduction and transportation of sperm cells which are needed for fertilization. *The Female Reproductive...

...Essay: Male and Female Reproductive System Do you know how you were born? Do you know how you came to be? The reproductive system is the system that made that all possible. Without the reproductive system you wouldn’t have been born. In order to produce offspring, the male and female reproductive systems have to be different. Each system has different parts, problems and care. Each system have different purposes, the male reproductive system’s function is to produce sperm, while the female reproductive system’s function is to produce ova, store ova and house a fertilized egg. The male reproductive system is divided into two categories: internal and external reproductive organs. External organs are outside the body and internal organs are inside the body. The external reproductive organs are the penis, testes, scrotum, epididymis, and somniferous tubules, which are in the testes. The penis allows liquid waste and semen to leave the body. The testes, which are comprised of somniferous tubules, produce sperm. Sperm mixes with seminal fluids to produce semen. Semen is released through the penis and sperm in the seminal fluid has the ability to fertilize an egg. The scrotum protects and holds the testes and epididymis. The epididymis stores sperm. It also allows them to mature The internal reproductive organs are the vas deferens, seminal vesicles, Cowper’s gland, and the prostate gland. The vas deferens extends from each epididymis. They allow the sperm to leave the scrotum...

Gonad: Reproductive organs (Testes in males and ovaries in females) that produce gametes and secrete sex hormones. * Define gynecology, urology & andrology Gynecology: The branch of medicine that is concerned with the diagnosis and treatment of diseases of the female reproductive system. Urology: The study of the urinary system, as well as the branch of medicine that deals with the diagnosis and treatment of the male reproductive system. Andrology: The branch of medicine that deals with male disorders, like infertility and sexual dysfunction. 28.1 MALE REPRODUCTIVE SYSTEM * The male reproductive organs & the functions of the male reproductive system (Figure 28.1) * The male reproductive organs include: the testes1, a system of ducts2 (including the epididymis, ductus vas deferens, ejaculatory ducts, and urethra), accessory sex glands3 (seminal vesicles, prostate, and bulbourethral glands) and several supporting structures including the scrotum4 and penis5. Functions: 1. The testes produce sperm and male sex hormone, testosterone. 2. The ducts transport, store and assist in maturation of sperm. 3. The accessory sex glands secrete most of the liquid portion of semen. 4. The penis contains the urethra, a passageway for ejaculation of semen and excretion of urine. Major organs include:...

...REPRODUCTIVE SYSTEM FUNCTIONS ➢ The major function of the reproductive system is to make sure that the human species survives. ➢ It is not necessary for every human being to produce children, but in order to continue our human species, at least some people have to have children. ➢ The four main functions of the human reproductive system are: • To produce egg and sperm cells, • To transport and sustain these cells, • To nurture the developing offspring, and • To produce hormones. MAJOR ORGANS ➢ In the human reproductive system, the major organs include the external genitalia and many internal organs including gonads producing gametes and hormones. ➢ These hormones are needed in the maturing of the human reproductive system, the development of sexual characteristics, and the importance in regulating the normal physiology of the human reproductive system. ➢ In the males, the major organ of the reproductive system is the penis, and in the females it is the vagina. FEMALE REPRODUCTIVE SYSTEM Female External Reproductive Organs A female's external part of the reproductive organs is called the vulva, meaning “covering.” The vulva is located between the legs and covers the opening to the vagina and other reproductive organs located inside the body. Female Internal Reproductive Organs The female has four internal reproductive organs: • the vagina, • uterus, • fallopian...

...help provide support by anchoring the plant and absorbing water and nutrients needed for growth. They can also store sugars and carbohydrates that the plant uses to carry out other functions. Plants can have either a taproot system (such as carrots) or afibrous root system (such as turf grass). In both cases, the roots are what carries the water and nutrients needed for plants to grow.(http://urbanext.illinois.edu/gpe/case1/c1facts2a.html) In other words the root is the life of a plant because it won’t grow without it The stem is one of two main structural axes of a vascular plant. The stem is normally divided into nodes and internodes, the nodes hold buds which grow into one or more leaves, inflorescence (flowers),conifer cones, roots, other stems etc. The internodes distance one node from another. The term shoots is often confused with stems; shoots generally refer to new fresh plant growth and does include stems but also to other structures like leaves or flowers. The other main structural axis of plants is the root. In most plants stems are located above the soil surface but some plants have underground stems. A stem develops buds and shoots and usually grows above the ground. Inside the stem, materials move up and down the tissues of the transport system. Stems have four main functions which are Support...

...The System at a Glance The human reproductive system is one of the most important systems in the body. Without this system humanity could not continue to function because humans would no longer be able to repopulate the earth and would soon go extinct. The system though, differs between the genders of male and female by having different organs, differing in the number of organs, and having different functions. These two different system setups work hand in hand to breed new life and like all other systems over time they begin to fail, have their own genetic issues, and can be damaged in various ways throughout the lifespan of a human. 1. The Male Reproductive System So let's begin by talking about the male reproductive system. This...

...Body Systems Preparation Part III In the reading from the book, Human Body Systems, team A will give a brief overview of the skeletal, muscular, encoring and male and female reproductive systems and explain what we did or did not already know, what we found interesting and why, as well as what we learned from this week that can help team A with week five presentation. In chapter eleven, on the skeletal system, the human skeleton consists of 206 bones and provides support to our bodies. After reading this chapter team A learned about rheumatoid arthritis. Rheumatoid arthritis is a disorder of the skeletal system. The most interesting finding about rheumatoid arthritis is that it is not a disease that results from wear and tear; rheumatoid arthritis is the result of an autoimmune disease. This is extremely interesting to Angelina because she would like to continue her education to help treat patients. Anyone can be affected by this disease at any given time and learning about it can help her understand the symptoms. The endocrine system consists of small glands that are strategically place throughout the body. These glands produce and release chemical substances called hormones. Hormone is a chemical that travels through the blood to cause effect in other areas of body function. What is interesting about hormones is that these chemicals affect five different areas of the body, homeostasis, growth and development, reproduction, energy production and behavior (Chiras, 2013)...

...sources you use. What is gender? What is sex in biological terms? Are gender and sex the same thing? Explain why or why not? Gender is basically the state of being either male or female, masculine or feminine. Sex biologically means the categorization of whether an organism is male or female, of having parts of the male reproductive system or female reproductive system. Although gender and sex have very similar meaning, generally they usually differ where majority relate reproductive traits to sex than gender. How do gender and sex contribute to the concepts and constructions of masculinity and femininity? Gender and sex contributes to the concepts of masculinity and femininity on a basis to where contemporary America believes that male is to masculinity as female is to femininity and the truth of the matter is that you can’t judge a person to be a male or female based on whether they are feminine or masculine because both males and females carry traits that are masculine and traits that are feminine. Do our concepts of gender and sex contribute to the ways we embrace gender and sex in diversity? Yes, I believe that our concepts on gender and sex contributes to the way that we embrace them in diversity because we tend to categorize certain aspects to what we feel a male/female should look like, sounds like, smell like, and act like and when someone doesn’t fit that we question their gender/sex instead of accepting them for who they are. Do our concepts...
