  1. Reproductive Anatomy

  2. Meet 'The Question Box'

  3. Female Anatomy: External • The external organs are contained in an area called the Vulva: • Outer labia • Inner labia • Hymen • Opening to the vagina • Clitoris

  4. Female Anatomy: Internal • Vagina: • Stretchable passage between the vulva, cervix, and uterus • About 4 to 5 inches in length • Also known as the: • birth canal • organ of intercourse

  5. Female Anatomy: Internal • Cervix: • Opening to the uterus • The cervix plays a very important role in reproduction. Without a “strong” cervix, a female would not be able to naturally hold a fetus • Uterus: • Also known as the womb • Lined by a thick blood filled blanket called the endometrium • The uterus is a very strong muscular organ. The function is to house and support the developing fetus

  6. Female Anatomy: Internal • Endometrium: • Develops throughout the menstrualcycle • Shed if fertilization and implantation do not occur. This is called menstruation • Fallopian Tubes: • Extend from the top of each side of the uterus each tube ends near an ovary • Outer edge of the tubes has fimbria that sweep the mature eggs from the ovary into the tube

  7. Female Anatomy: Internal • Ovaries: • Attached by ligaments to each side of the uterus and to the walls of the pelvis • Each ovary has thousands of follicles • Each follicle has an immature egg • Egg (Ovum): • Female reproductive cell • The largest human cell (about the side of a grain of salt)

  9. Male Anatomy • Penis: • Formed of spongy tissue that fills with blood and becomes erect during sexual excitement • Ejaculation: • Occurs from the penis • Not all erections end in ejaculations!

  10. Male Anatomy • Glan: • Soft top of the penis foreskin covers the glans in uncircumcised men. • Foreskin: • Retractable tube of skin that covers and protects the glans of the penis • Circumcision removes the foreskin

  11. Male Anatomy • Scrotum: • Sac of skin which holds the testes, Epididymidesand vas deferens • Keeps testes up to 5 degrees cooler than normal body temperature; to allow for sperm production • Also protects testes from injury to some degree

  12. Male Anatomy • Testes: • Two ball like glands • Produce sperm • Produce testosterone • Urethra: • Tube that runs from the bladder to the opening in the glans of the penis • Carriers urine from the bladder and semen from the vas deferens

  13. Male Anatomy • Epididymis: • Each is a tube tightly coiled over the top and behind each testes • Where the sperm matures • Vas Deferens: • Two long narrow tubes that carry the sperm from each epididymis to the seminal vesicles

  14. Male Anatomy • Prostate Gland: • Located below the bladder • Produces a thin fluid to help sperm move • Fertilizes sperm • Cowpers Gland: • Secrete fluids that male the seminal fluid sticky

  15. Male Anatomy • Seminal Vesicle: • Located beneath the bladder • Produce seminal fluid in which sperm move and are nourished • This fluid, along with secretions from the Prostate Gland and Cowper’s Gland is called semen • Semen: • Thick white fluid containing spermatozoa that is ejaculated by the male genital tract. • Semen does not consist of only sperm

  16. Activity: vocab matching With a partner, attempt to match the vocabulary with it's description. http://www.youtube.com/watch?v=dpWCd_i9pJs&list=PLYkDg7ymNvkiqmsBBehqh89DTEFaRurK

  17. Exit Ticket Question: What is the path traveled by a sperm cell? Journal:Was most of this new information to you or had you learned it before?
