Answer:
Male Reproductive System
1. Testes - The testes are responsible for making testosterone, the primary male sex hormone, and for producing sperm. Within the testes are coiled masses of tubes called seminiferous tubules. These tubules are responsible for producing the sperm cells through a process called spermatogenesis.
2. Scrotum - The bag of skin that holds and helps to protect the testicles. The testicles make sperm and, to do this, the temperature of the testicles needs to be cooler than the inside of the body.
3. Epididymis - The epididymis is a long, coiled tube that rests on the backside of each testicle. It carries and stores sperm cells that are created in the testes. It's also the job of the epididymis to bring the sperm to maturity — the sperm that emerge from the testes are immature and incapable of fertilization.
4. Vas Deferens - The vas deferens is a long, muscular tube that travels from the epididymis into the pelvic cavity, to just behind the bladder. The vas deferens transports mature sperm to the urethra in preparation for ejaculation.
5. Prostate Gland - The prostate's most important function is the production of a fluid that, together with sperm cells from the testicles and fluids from other glands, makes up semen. The muscles of the prostate also ensure that the semen is forcefully pressed into the urethra and then expelled outwards during ejaculation.
Female Reproductive System
1. Ovary - Ovaries make eggs and hormones like estrogen and progesterone. These hormones help girls develop, and make it possible for a woman to have a baby. The ovaries release an egg as part of a woman's cycle.
2. Cervix - The cervix performs two main functions: It facilitates the passage of sperm into the uterine cavity. This is achieved via dilation of the external and internal os.
3. Fallopian Tube - A female structures that transport the ova from the ovary to the uterus each month. In the presence of sperm and fertilization, the uterine tubes transport the fertilized egg to the uterus for implantation.
4. Uterus - It receives the fertilized egg and supports its development during pregnancy.
5. Vagina - The vagina serves three purposes: It's where the penis is inserted during sexual intercourse. It's the pathway (the birth canal) through which a baby leaves a woman's body during childbirth. It's the route through which menstrual blood leaves the body during periods.
