- 3. • Explain therole of hormones involved in the female and male reproductive systems Objective:
- 4. The Male ReproductiveSystem
- 5. • Pouch ofskin that hangs behind the penis, houses the testes, and protects the sperm keeping the temperature of the testes slightly lower than the normal body temperature in order for the sperm to survive. Scrotum The Male Reproductive System
- 6. • Made upof coiled tubules in which sperm are produced in which the sperm are produced. • Produce the male sex hormones called testosterone for the production of sperm. Testes The Male Reproductive System
- 7. • Coiled J-shapedtube located on the back of each testicle. • Stores the sperm for two to four days after they have been produced. Epididymis The Male Reproductive System
- 8. • Tube thatreceives sperm from the epididymis of each testicle Vas deferens The Male Reproductive System
- 9. • Soft, tubularorgan that hangs in front of the body and is the external sexual organ of the male through which sperm are delivered into the female’s body. • Contains erectile tissue that makes the penis larger and stiffer due to increase flow of blood during ejaculation. Penis The Male Reproductive System
- 10. • Tube thatpasses through the penis to the outside of the body, which carries urine and semen. Urethra The Male Reproductive System
- 11. • About 18inches (45 cm) long and loops over the bladder Vas deferens The Glands and Ducts of the Male Reproductive Organ • The valve within the urethra prevents the mixing of urine and sperm. Urethra • The two seminal vesicles at the base of the bladder secrete a thick fluid that nourishes the sperm. Seminal Vesicles • The tubes that are lined with muscles which contract to force semen out of the body during ejaculation. Ejaculatory Ducts
- 12. • Produced bythe testes to fertilize the egg to become a matured ovum. • Semen – mixture of sperm and the nutrient secretion from the prostate gland and seminal vesicle. The Sperm Cell
- 13. The Female ReproductiveSystem
- 14. • Small andalmond-shaped organs that secrete hormones called estrogen and progesterone to produce mature egg cells • Ovulation – the ovaries produce and release one ripened egg every 28 days Ovaries The Female Reproductive System
- 15. • Two veryfine tubes that extend from each ovary into the uterus. • Contain the egg until fertilization takes place and to provide a passageway leading the sperm to the egg and the fertilized egg to the uterus Fallopian tubes The Female Reproductive System
- 16. • Hollow, muscular,pear- shaped organ located between the two ovaries. • Location where the fertilized egg develops and grows into a baby. • Sheds if the egg remains unfertilized then leaves the body as menstrual discharge. Uterus or Womb The Female Reproductive System
- 17. • Narrow structurewithin an inch-long canal connecting the lower end of the uterus to the upper portion of the vagina. Cervix The Female Reproductive System
- 18. • Hollow tubeleading from the cervix to the outside of the body. • The wall is elastic, which allows it to expand during childbirth and sexual intercourse. Vagina or Birth canal The Female Reproductive System
- 19. • External genitaliathat includes: • Mons veneris/pubis • Labia minora • Labia majora • Clitoris • Vaginal orifice Vulva The Female Reproductive System

- 22. • composed ofglands that secrete different types of hormones • essential in regulating growth and development, metabolism, as well as reproductive processes, and mood The Endocrine System
- 23. • Endocrine glandssecrete chemicals known as hormones into the bloodstream, which carries them throughout the body. • Hormones are chemical messengers, carrying instructions to cells to change their activities. The Endocrine System
- 24. • A glandis an organ in which cells secrete materials to be brought to the different regions of the body, sometimes via tube-like structures called ducts. The Endocrine System
- 25. • Endocrine glands(endo mean “within,” krinein means “separate,” i.e., to secrete) The Endocrine System
- 26. • The pituitarygland is a part of your endocrine system. Its main function is to secrete hormones into your bloodstream. • The pituitary gland is sometimes called the master gland because it’s involved in so many processes. The Pituitary Gland
- 27. Major Hormones Involvedin the Female and Male Reproductive Systems
- 28. Major Hormones Involvedin the Female and Male Reproductive Systems
- 29. Hormones of thepituitary gland • follicle-stimulating hormone (FSH) - seminiferous tubules of the testes become active and start producing sperms • interstitial cell-stimulating hormone (ICSH) - stimulates a group of cells called the interstitial cell, surrounding the seminiferous tubules to produce hormone testosterone The Role of Hormones in Male and Female Reproductive Systems Male Reproductive System
- 30. Hormones of thepituitary gland • follicle-stimulating hormone (FSH) - controls the growth and release of eggs from the ovaries The Role of Hormones in Male and Female Reproductive Systems Female Reproductive System
- 31. • Estrogen isthe reproductive hormone in females that assists in endometrial re-growth, ovulation, and calcium absorption; it is also responsible for females' secondary sexual characteristics. • Progesterone assists in endometrial re-growth and inhibition of follicle-stimulating hormone and luteinizing hormone release. While other hormones prepare the uterus so a baby can grow in it, other hormones still control the stretching of the uterus during pregnancy.
