  1. THE REPRODUCTIVE SYSTEM: MALE & FEMALE ANATOMY

  2. REPRODUCTIVE SYSTEM: A system that produces haploid sex cells called gametes ( egg & sperm)

  3. The male:

  4. Male reproductive system Ureter Seminal Vesicle bladder Rectum Prostate Gland Vas Deferens Penis Epididymis Urethra Testes Scrotum

  5. TESTES:the male organs that produce sperm cells and the hormoneTestosterone Located inside a sac called thescrotum EPIDIDYMIS TESTIS SCROTUM

  6. SCROTUM: located outside thebody -protects the testes - keeps them slightly cooler than body temperature - important for sperm cell development & survival.

  7. SEMINIFEROUS TUBULES: Tightly coiled tubules that give the testes their shape. It is also where sperm is produced. Seminiferous tubules

  8. SPERM: head Middle section Small, motile gametes produced in the testes and used for reproduction - ~ 700 million produced each day Tail (flagellum)

  9. EPIDIDYMIS: A coiled tube that lies alongside each testis inside the scrotum . It iswheresperm is stored until it is matured.

  10. VAS DEFERENS: A duct that transports sperm from the epididymis to the ejaculatory duct & urethra. It is thestructurethat iscutduring avasectomy.

  11. EJACULATORY DUCT & URETHRA Empties into the urethra. Passes through the penisandcarries semen andurinebut at different times

  12. PENIS: (surrounds the urethra) Made of spongy erectile tissue that expands when filled with blood. Propels semen (containing sperm, fructose & other fluids made by the prostate gland) during ejaculation. Semen also cleanses the urethra

  13. PATHWAY OF SPERM OUT OF BODY BLADDER Ejaculatory duct urethra Vas deferens epididymis penis testis

  14. Reproductive system - female

  15. The female reproductive system: Fallopian Tubes Ovary Uterus Cervix Vagina Labia

  16. The ovary: The female organ that usually releases one ovum (egg) a month Produces the hormones estrogen and progesterone. Contains about 400,000 follicles which is where the egg develops and matures.

  17. Fallopian tubes: Pathway through which an egg travels to the uterus. Fertilization occurs here. Structure that is cut/tied during a tubal ligation.

  18. Uterus: Muscular, pear-shaped organ where the fetus develops. Cervix connects the uterus to the vagina Inner layer called the endometrium where fertilized egg plants itself.

  19. Vagina: * Tube shaped organ that opens to the outside of the body * Receives the penis during intercourse - it is also where sperm enters. * Serves as the birth canal where the baby exits the body.

  20. Pathway of sperm during intercourse: Fallopian tubes uterus cervix vagina

  21. Pathway of egg : Fallopian tubes Uterus If fertilized, implants in uterine wall. If not, discharged with uterine wallduring menstruation.
