8. What is the reproductive system?

9. Reproductive System Is a collection of organs and a network of hormone production that work together to create life.

10. WHY DO WE NEED TO REPRODUCE?

11. We need to reproduce in order to: 1. To ensure the survival of the species.

12. We need to reproduce in order to: 1. To ensure the survival of the species. 2. To produce egg and sperm cell.

13. We need to reproduce in order to: 1. To ensure the survival of the species. 2. To produce egg and sperm cell. 3. To transport and sustain these cells.

14. We need to reproduce in order to: 1. To ensure the survival of the species. 2. To produce egg and sperm cell. 3. To transport and sustain these cells. 4. To nurture the developing offspring.

15. We need to reproduce in order to: 1. To ensure the survival of the species. 2. To produce egg and sperm cell. 3. To transport and sustain these cells. 4. To nurture the developing offspring. 5. To produce hormones.

16. What is your reproductive system?

17. The two types of human reproductive system

18. MALE REPRODUCTIVE SYSTEM

19. Function of the Male Reproductive system: 1. Secretion of the male sex hormones.

20. Function of the Male Reproductive system: 1. Secretion of the male sex hormones. 2. Production of sperm cells.

21. Function of the Male Reproductive system: 1. Secretion of the male sex hormones. 2. Production of sperm cells. 3. Transfer of sperm cells.

22. PARTS, FUNCTION AND MECHANISM

23. PARTS, FUNCTION AND MECHANISM 1. Penis – is the male organ used for sexual reproduction and urination. The erectile tissues fill with blood during sexual arousal.

24. PARTS, FUNCTION AND MECHANISM 1. Penis – is the male organ used for sexual reproduction and urination. It has three parts: glans: the head where the urethra is present, body: the mid part of the penis, root: near the scrotum.

25. PARTS, FUNCTION AND MECHANISM 2. Scrotum – located behind the penis and holds testicles/testes inside it.

26. Why are the testes and testicles outside the body?

27. PARTS, FUNCTION AND MECHANISM 2. Scrotum – located behind the penis and holds testicles/testes inside it. - seminiferous tubules: inside of the testes that produce sperm.

28. PARTS, FUNCTION AND MECHANISM 3. Epididymis – where the sperm cells mature, carried, and stored.

29. PARTS, FUNCTION AND MECHANISM 4. Vas deferens – the passage way of sperm from testes to the urethra.

30. PARTS, FUNCTION AND MECHANISM 5. Testes – It produces testosterone or the primary male sex hormone.

31. WHAT IS THE DEFERENCE BETWEEN SEMEN AND SPERM?

32. PARTS, FUNCTION AND MECHANISM 6. Seminal Vesicles – attached to the vas deferens and produces seminal fluid ( that contains the sugar fructose, proteins, citric acid, inorganic phosphorus, potassium, and prostaglandins) that nourishes the sperm and helps sperm travel.

33. PARTS, FUNCTION AND MECHANISM 7. Prostrate Gland – Produces fluid ( alkaline fluid) which is added to the sperm cells and semen.

34. PARTS, FUNCTION AND MECHANISM 8. B ulbourethral glands (also called Cowper's glands ) – produce clear fluids that helps lubricate and neutralizes the acidity of urine that are left in the urethra.

35. How much sperm is in 3.5 ml of SEMEN? 400 million sperm

36. FEMALE REPRODUCTIVE SYSTEM

37. FUNCTION OF THE FEMALE REPRODUCTIVE SYSTEM: 1. P roducing gametes (called eggs or ova), certain sex hormones, and; 2. M aintaining fertilized eggs as they develop into mature fetuses and become ready for delivery.

38. PARTS, FUNCTION AND MECHANISM 1. Ovary/Ovaries – produce and develop female sex cells called ova or eggs. - estrogen and progesterone: regulate the reproductive process.

39. PARTS, FUNCTION AND MECHANISM 2. Fallopian Tubes – it is where the egg or ova travels from ovaries to the uterus. - fimbriae tube: a re small, fingerlike projections connected to the end of the fallopian tubes, through which eggs move from the ovaries to the uterus.

40. PARTS, FUNCTION AND MECHANISM 3. Uterus (womb)– a hollow organ where the egg is deposited after traveling. - when the egg is fertilized, pregnancy is the result.

41. PARTS, FUNCTION AND MECHANISM 3. Uterus (womb) – a hollow organ where the egg is deposited after traveling. - the egg gets embedded onto the uterus and becomes fetus. - uterus widens as the fetus becomes baby.

42. PARTS, FUNCTION AND MECHANISM 4. Cervix – serves as the gate keeper that controls the flow of substance. - it protects the developing fetus from contamination by external pathogens.

43. PARTS, FUNCTION AND MECHANISM 4. Cervix – serves as the gate keeper that controls the flow of substance. - During childbirth, it becomes wider for around 10 cm in diameter.

44. PARTS, FUNCTION AND MECHANISM 4. Cervix – serves as the gate keeper that controls the flow of substance. - it allows the passage of menstrual fluid or baby.

45. PARTS, FUNCTION AND MECHANISM 5. Vagina – an elastic and muscular tube that connects the uterus of a woman to the vulva. - It is where the fetus passes through during birth.

46. PARTS, FUNCTION AND MECHANISM 6. Vulva – the external or outer parts of the female reproductive system. - composed of various tissues( mons pubis, labia majora , labia minora , clitoris, vestibular bulbs, vulva vestibule, Bartholin's glands, Skene's glands, urethra, and vaginal opening .) and skins that protect the opening of the vagina.

47. ACTIVITY #2: Where is my route? Direction: In 10 minutes, using the picture of a male and female reproductive system, illustrate the pathway of sperm for male and egg cell for female reproductive system.

49. *Uterus *Ovary * Fimbriae tube *Fallopian tube

50. FOLLOW UP QUESTIONS 1. What is the pathway of sperm cell of male and egg cell of female for reproduction? 2. What is the significance of the mechanism of this organ system? 3. What do you think will happen if this organ system fails in its function?
