  1. Stages of Life

  2. 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

  3. 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

  4. 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

  5. Terms to know • Prostate Gland • Sperm • Testicles • Semen • Testosterone • Scrotum • Seminiferous Tubules • Genes • Vas Deferens • Seminal Vesicles • Cowper’s Gland • Urethra • Epididymis • Penis

  6. 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

  7. 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

  8. 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.

  9. The Female Reproductive System • Common Reproductive Problems • Many problems related to the Menstrual Cycle • Irregular periods • Heavy flow, or light flow normal • Cramps are normal • Page 224 • Caring for the Female Body • Bathe everyday • Regular checkups • Abstain from sex • Good hygiene during periods

  10. Terms • Uterus • Endometrium • Ovum • Ovaries • Fallopian tube • Cervix • Vagina • Breast • Ovulation • Menstruation
