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 Male Reproductive System • Male reproductive problems – Check yourself regularly – Be aware of Noticeable Symptoms: • Uncomfortable rash • A sore or lump • Painful urination • Some problems do not have symptoms • Caring for the male body – – – – Bath every day -wear protective gear for sports -regular checkups -abstain from sex Terms to know • • • • • • • • • • • • • • Prostate Gland Sperm Testicles Semen Testosterone Scrotum Seminiferous Tubules Genes Vas Deferens Seminal Vesicles Cowper’s Gland Urethra Epididymis Penis 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.
