1.-HUMAN-REPRODUCTIVE-ORGAN AND ITS FUNCTIONS

Human Reproductive Organ

1. HUMAN REPRODUCTIVE ORGAN

2. OBJECTIVES DEFINE REPRODUCTIVE SYSTEM IDENTIFY THE FUNCTION OF EVERY PARTS OF MALE/FEMALE REPRODUCTIVE SYSTEM DRAW AND LABEL THE PARTS OF REPRODUCTIVE SYSTEM OF MALE AND FEMALE

3. OVERVIEW Every human being possess a reproductive system. The reproductive system helps him/her to reproduce another human being. We are product of reproduction.

4. REPRODUCTIVE SYSTEM The reproductive system  is a system of sex organs within an organism which work together for the purpose of sexual reproduction.

5. MALE REPRODUCTIVE ORGAN

6. MAJOR PARTS OF MALE REPRODUCTIVE ORGAN TESTES SCROTUM PENIS URETHRA EPIDIDYMIS VAS DEFERENCE PROSTATE GLAND COWPER ’ S GLAND SEMINAL VESICLE

7. Testis (testes in plural) typically paired, the testis consists of many highly coiled tubes or ducts surrounded by several layers of connective tissues; found inside the scrotum sac scrotum. produces sperm cells and secretes the male sex hormones (androgen and testosterone)

8. Scrotal sac or scrotum external saclike structure with temperature slightly lower than that of the rest of the body holds the testis/testes

9. Penis composed the spongy erectile tissues; its head is covered by a foreskin, which can be removed through circumcision deposits sperm into the vagina

10. Urethra a duct that runs through the length of the penis and opens to the outside serves as the passageway for both sperm and urine; has an opening that closes to pass one at a time

11. Epididymis long, narrow, flattened, highly coiled cumulated ducts lying on the edge of the posterior border of the testes stores mature sperm and is site where the sperm cells gain the ability to move which is necessary for fertilization

12. Vas deference ( sperm duct ) a short muscular duct Passageway of fluid that neutralize to the urethra; stores sperm

13. Prostate gland Thumb-sized, it consists of muscular and glandular tissues that lie around the base of the bladder Secretes a fluid that neutralizes the acidity of the vagina to ensure the survival of the sperm; aids in sperm motility

14. Cowper ’ s gland A pair of pea-sized gland along the urethra and below the prostate gland Secrete a fluid that may serve as lubricant and urine neutralizer

15. Seminal vesicle A pair of glands found between the bladder and the rectum Secrete a fluid that contains fructose (energy source for sperm)

16. How Does the Male Reproductive System Function? The entire male reproductive system is dependent on hormones, which are chemicals that regulate the activity of many different types of cells or organs. The primary hormones involved in the male reproductive system are follicle-stimulating hormone ,  luteinizing hormone , androgen and testosterone .

17. Follicle-stimulating hormone is necessary for sperm production (spermatogenesis)

18. Luteinizing hormone stimulates the production of testosterone, which is also needed to make sperm.

19. Testosterone is responsible for the development of male characteristics, including muscle mass and strength, fat distribution, bone mass, facial hair growth, voice change, and sex drive.

20. Androgens  are produced by the body in greater amounts in males.

21. A system of sex organs within an organism which work together for the purpose of sexual reproduction. It produces sperm cells and secretes the male sex hormones. It holds the testis/testes. It composed the spongy erectile tissues. It serves as the passageway for both sperm and urine. A long, narrow, flattened, highly coiled cumulated ducts lying on the edge of the posterior border of the testes. A short muscular duct. A thumb-sized, it consists of muscular and glandular tissues that lie around the base of the bladder . A pair of pea-sized gland along the urethra and below the prostate gland. It Secrete a fluid that contains fructose (energy source for sperm).

23. FEMALE REPRODUCTIVE ORGAN

24. MAJOR PARTS OF FEMALE REPRODUCTIVE ORGAN Ovaries Fallopian Tubes Uterus ( womb ) Cervix Vagina ( birth canal ) Vulva - mons veneris -labia minora -labia majora -clitoris -vaginal orifice

25. ovaries small, flattened , elongated organs on both sides of the uterus alternately produce the female sex cells (egg or ova) and secretes the female hormones (estrogen and progesterone)

26. Fallopian tubes a pair of ducts leading from the ovaries to the uterus Pathway where the ova travels from the ovary to the uterus

27. uterus Hollow, muscular, pear –shaped organ located between the two ovaries It is where fertilized egg will develop and grow into baby.

28. cervix Neck of the uterus that opens to the vagina Passage way for menstrual flow; passage way for sperm

29. vagina A thin-walled passageway through which sperm can enter and swim to the fallopian tube Passageway for menstrual flow and baby to the outside

30. vulva The external genitalia

31. Mons veneris The hairy skin-covered pad of fat over the pubic bone

32. Labia minora the small lips covered with modified skin

33. Labia majora the large lips covered with pubic hair

34. clitoris The small almond-shaped erectile tissue located below junction of two minor

35. Vagina orifice The opening into the vagina

36. There are four major hormones (chemicals that stimulate or regulate the activity of cells or organs) involved in the menstrual cycle: follicle-stimulating hormone, luteinizing hormone, estrogen, and progesterone.

37. Progesterone helps to maintain pregnancies and implant an egg in the uterus. Estrogen makes the bones smaller and shorter, the pelvis broader, and the shoulders narrower.

38. The opening into the vagina. The small almond-shaped erectile tissue located below junction of two minor. The large lips covered with pubic hair. The small lips covered with modified skin. The hairy skin-covered pad of fat over the pubic bone A small, flattened , elongated organs on both sides of the uterus Passageway for menstrual flow and baby to the outside Neck of the uterus that opens to the vagina. It is where fertilized egg will develop and grow into baby. A pair of ducts leading from the ovaries to the uterus.
