the reproductive system
Female:
Ovaries- The ovaries store eggs and release them during the menstrual cycle.
Fallopian Tubes- The fallopian tubes lead the egg from the ovaries to the uterus.
Uterus- The uterus is where an egg attaches (to the uterine lining) and grows, and where the fetus is until it is born.
Vagina- The vagina is the female sex organ. It provides a passageway for the uterine lining to shed during menstruation and is also the birth canal.
Male:
Penis- The penis is the male sex organ, and is used for reproduction and to expel urine from the body.
Testicles- The testicles produce and store sperm and produce testosterone.
Scrotum- The scrotum supports the testicles outside the body, and keeps them at the correct temperature.
Epididymis- Stores sperm in preparation for ejaculation.
Vas Deferens- Transports sperm from the epididymis for ejaculation.
Seminal Vesicles- Produces the fluid that sperm cells are in once outside the body.
Prostate Gland- Secretes hormones that are mixed into seminal fluid.
Life of a Sperm Cell:
Sperm cells are produced in the testicles, and are then moved to the epididymis for storage and maturation. Once the sperm is ready to be excreted, it moves to the vas deferens, and then recieves seminal fluid from the seminal vesicle. The sperm then move into the urethra after passing the prostate gland, where they receive a milky fluid and the sperm are in a solution called semen. Finally, the semen is expelled from the body.
Life of an Egg Cell:
Eggs are fully mature in the ovaries, and once an egg is released, it travels down the fallopian tube towards the uterus. In the fallopian tube, the egg can be fertilized. If it is fertilized, it moves to the uterus where it attaches to the wall of the uterus, and matures into a fetus until it is born. If left unfertilized, the egg does not attach to the wall of the uterus, and when the uterine lining is shed, the egg leaves the body with it.
