Stages of Life
The Male Reproductive System The male body Prostate gland- a gland in the male reproductive system that makes fluid that helps carry sperm. Sperm- the male sex cell Testes(testicles)- the organs the make the sperm and the primary male sex hormone, Testosterone Scrotum- sac of skin that hold the testes. Epididymis- where sperm mature Penis- Exit point for the body
The Path Traveled by Sperm Seminiferous Tubules- structures where cells are made, located in the testes Genes- instructions for how a person’s body looks and functions They then move to epididymis where they mature Once mature the sperm moves into tubes called Vas Deferens The sperm then passes through the Seminal Vesicles, which provide the sperm with fluid to help it on it’s journey, Semen The sperm then passes through the prostate gland, and the Cowper’s gland, where it recieves more fluid. The sperm then enters the Urethra, which runs through the penis and out the body. After two weeks in the body the sperm is reabsorbed by the body

The Female Reproductive System The female body Uterus- a muscular organ of the female reproductive system that holds a fetus during pregnancy Endometrium- the lining of the uterus Ovum- women’s sex cell Ovaries- where eggs, or ova, are made and stored Female sex hormone also produced here, Estrogen Fallopian Tube- pathway for egg to travel Cervix-lower part of the uterus, where the uterus meets the vagina Vagina- connects the outside of the body with the uterus Breast- also a part of the female reproductive system
Ovulation/Menstruation Ovulation- beginning at puberty, one of the ovaries releases a mature egg every month. Eggs contain one half of the woman’s genes One egg will be most dominate, other will be reabsorbed by the body Menstruation- the monthly breakdown and shedding of the endometrium, a.k.a. a period
Path of an Egg The egg or ova forms in the ovaries(day1-13) The egg is then released from the Ovary(Ovulation, day14) The fallopian tube then draws the egg in, along with other fluids, and sends it towards the uterus(15-28) If the egg is fertilzed a pregnancy begins If the egg is unfertilized Menstruation continues(days 1-5) Full cycle takes 28 days and is known as the menstrual cycle.
