The document discusses the male and female reproductive systems. It provides descriptions and labeled diagrams of the key parts of each system, including ovaries, fallopian tubes, uterus, vagina, testes, epididymis, vas deferens, seminal vesicles, prostate gland, and penis. It explains the functions of each part, such as production of eggs and sperm, temporary sperm storage, secretion of fluids, and roles in fertilization and childbirth. The document asks which system a person would choose to remove if they had to remove one, suggesting the reproductive system as it is not required for survival but instead ensures continuation of the species.

12. • The reproductive system is not needed to
keep you alive like all of the other systems.
– It is responsible for keeping the species from going
extinct.

14. Life begins in the reproductive
system of the female, set inside
the pelvic cavity.

23. Functions of Ovary
 For production of female gametes
(ova/eggs)
 For production of female sex hormones

24. Ovulation
• The release of an ovum from an ovary

25. Fallopian tube / Oviduct
• Carries the ovum forward by
– the beating action of the cilia
on its inner surface
– the contraction of muscles of
oviduct
• Place for fertilization (upper part)

ureter
urinary bladder
prostate gland
urethra
sperm duct
Cowper’s gland
penis
epididymis
testis
scrotum

37. Male Reproductive System
Male accessory sex organs
 epididymis
 vas deferens
 seminal vesicles
 prostate gland
 urethra

38. Male Reproductive System
seminal
vesicle
prostate
gland
Cowper’s
gland
secrete
seminal
fluid

39. Functions of Seminal Fluid
 To provide a medium for the sperms to
swim
 To activate and nourish the sperms
 To neutralize the acidity in female
reproductive tract

40. Semen
 Seminal fluid is thick, yellowish, and
alkaline.
 It contains mucus, fructose, a
coagulating enzyme, ascorbic acid,
and prostaglandins.

41. Penis
Fig 3-21

43. Testes
• For production of male gametes (sperms)
• For production of male sex hormones
Testis :
showing
sperm
production

44. Epididymis
 For temporarily storage of sperms
 During copulation, muscles of epididymis
contract to release sperms
epididymis
vas deferens
(sperm duct)
sperm tubules

46. Soft penis not
sexually aroused
testis
erectile tissue filled
with blood
Penis becomes
erect when the
man is sexually
aroused
Transfer of semen
Penis is inserted into the vagina  Movement  Muscles of
epididymis contract  Eject semen  Ejaculation
Sperms are transferred from a man into a woman’s body.
Copulation
