  1. Lesson 1 The Reproductive System

  2. Do Now • Why is it important to understand the functioning of both the male and female reproductive systems?

  3. Male Reproductive System • Sperm- male reproductive cells that start being produced during puberty. Produced in the testes. • Semen- the mixture of sperm and seminal fluid. • Ejaculation- Muscular contractions that force semen through the urethra and out of the body.

  4. Male Reproductive System • Urethra- a tube that carries urine and sperm to the outside of the body • Penis- the external sexual organ • Testes- or testicles, are two small glands that produce sperm and hormones. • Scrotum- a muscular sac that contains the testes.

  5. Problems of the Male Reproductive System • Inguinal hernia- a tissue tear that allows part of the intestine to push into the scrotum. Caused from heavy lifting. • Sterility- inability to produce enough healthy sperm to reproduce. • STD’s- infections that are spread during sexual contact. • Cancer- uncontrolled cell growth that destroys healthy tissue.

  6. Care of the Male Reproductive System • Practice self-examinations • Bathe regularly • Wear protective gear • Practice abstinence

  7. Female reproductive system • Ovaries-produces and contains the eggs, along with hormones estrogen. • Fallopian tubes-carries the eggs from the ovaries to the uterus • Uterus-shelters and nourishes the fetus • Endometrium- the lining of the uterus • Cervix-the opening of the uterus • Vagina-a muscular passageway from the uterus to the outside of the body. • Labia-layers of tissue that cover the opening of the vagina

  8. The Menstrual Cycle • Ovulation- the release of one mature egg cell each month • Menstruation-the flow of the uterine lining out of the body. • Menstrual cycle-the sequence of events in the system that occurs from one menstruation to another. • Menopause- a period marking the end of a female’s reproductive years. Between 40-60

  9. Problems of the female reproductive system • Premenstrual syndrome(PMS)- a collection of physical and emotional changes before and during menstruation. • Toxic shock syndrome-serious bacterial infection associated with incorrect tampon use. Can cause death if not treated • Infertility-inability to reproduce because of blocked fallopian tubes or failure to produce eggs. • Ovarian cysts- growths on the ovaries. Any pain,swelling,or bloating should be checked by a doctor. • STD’s and Cancer-

  10. Care of the female reproductive system • Examine your breasts • Bathe regularly • Record your menstrual periods • Annually visit appropriate doctors • Practice abstinence
