Reproductive System Male and female

Male & female reproductive system

1. Welcome TO My Presentation

2. Presentation on Reproductive System

3. Definition The organs and glands in the body that aid in the production of new offspring.

4. Type Of Reproduction Asexual Reproduction: It occurs by simple division of unicellular organism Sexual reproduction: It occurs by sexual contact of male and female

5. Criteria of reproductive System Chromosomal sex Gonadal sex Phenotypic sex Psychological sex

6. Function Of Reproductive System Performs the process of reproduction Control sexual function and behavior

7. Function Of Male reproductive System Spermatogenesis: Which means simply the formation of sperm maintain & transport sperm and semen ( protective fluid )

8. Male Reproductive Organ External Organ Penis Urethra Scrotum Internal Organ Testis Vas-Deferens Seminal vesicle Prostate Gland

9. Parts of penis Penis Root Glans Body

10. Parts Of Testes

11. Female Reproductive System External Organs Internal Organs

12. External Organs Labia Majora Labia Minora Clitoris Vaginal- oregis Huymen Mons-pubic

13. Internal Organs Vaginal Canal Uterus Fallopintube Ovary

14. Female Sex Hormones A. Hypothalamic releasing hormone Gonadotropin releasing hormone Luteinizing hormone B. Anterior pituitary hormone Follicle stimulating hormone Luteinizing hormone C. Ovarian hormone Estrogen Progesterone

15. Parts of Ovary a . Two poles Upper pole Lower pole b. Two surface Medial surface Lateral surface

16. Uterus: The uterus is a hollow cavity about size of a pear that exists to house a developing fertilized egg. Vagina: The vagina receives the penis and semen during sexual inter course and also provides a passageway for menstrual blood to revel the body

17. Ovarian cycle The regular maturation of group primordial follicle and the periodic shedding of an ocyte constitute a cyclic change in the ovary is called ovarian cycle

18. Menstruation Cycle The monthly rhythmic changes in the rates of secretion of female hormones and corresponding changes in ovaries and sexual organ as well is known as menstrual cycle. May be regarded a periodic preparation for fertilization and pregnancy.

19. P regnancy The period from conception to birth. After the egg is fertilized by sperm and implanted in the lining of the uterus it develop into the placenta and embryo and latter into a fetus.

20. Lactation The process of formation and secretion of milk in the alveoli of breast and its expulsion from mammary gland is called lactation.

21. Role of hormone in lactation Estrogen: Developed stroma & duct system of the breast Progestron : Responsible for development of lobulc and alveoli of the breast. Prolactin: Final development of breast Growth hormone Thyroid hormone

22. Placenta Placenta is a flattened, dissocial mass with circular outline a diameter of 15-25 cm. it is an organ in which blood vessel of the embryo are brought into relationship with the blood of the mother

23. Hormone in placenta Estrogen Progesterone

24. Function of placenta Transport of oxygen from mother to fetus Transport of nutrient, hormone, vitamin to the fetus Protective membrane for the fetus
