  4. Secondary Gender Characteristics

  5. MALE REPRODUCTIVE SYSTEM Bladder 1 Seminal Vesicle Vas Deferens 2 10 Urethra 3 Prostate 9 Penis 4 Bulbo-urethral gland 8 Epididymis 5 Seminal Vesicle 10 Testicle 6 Prostate 9 Scrotum 7 Bulbo-urethral gland 8

  6. Functions of the structures: 1. The Bladder: - storage area for urine

  7. The Urethra: - passage for urine and semen to exit the body

  8. The Prostate Gland: • Produces a fluid that helps form semen • Helps control flow of urine out of body

  9. 4. The Penis: • The external male reproductive organ used for urination and reproduction

  10. 5. The Scrotum: • Helps protect the testicle • Helps maintain temperature in the testicle

  11. 6. The Testicle: • Produces testosterone • Produces sperm

  12. 7. The Epididymis: • Storage area for sperm

  13. 8. The Vas Deferens: • Passage for sperm to travel from epididymis to the seminal vesicle • Sight of a vasectomy

  14. 9. The Seminal Vesicle: • production of fluid that makes up a significant percentage of semen occurs here

  15. 7. The Seminal Vesicle: Is there a difference between sperm and semen? Seminal Vesicle

  16. To the Seminal Vesicle VASECTOMY Vas Deferens From Epididymis

  17. 10. The Bulbourethral Gland: • discharges a component of seminal fluid into the urethra • the purpose of this fluid is to help lubricate the reproductive organs before sexual intercourse • the male can not feel when this fluid is discharged • this fluid CAN CONTAIN SPERM!!!!!!!!!!!!

  18. FEMALE REPRODUCTIVE SYSTEM Fallopian Tubes 1 Ovum 2 Ovary 3 Uterus 4 Bladder 5 Cervix 6 Uterine Lining 9 Urethra 7 Vagina 8

  19. Functions of structures: • Ovaries: • Produce female hormones • Produce ovum(mature eggs)

  20. 2. Fallopian tubes: • Passage for released eggs to travel from ovary to the uterus • Sight of conception

  21. 3. Uterus: • Organ where developing fetus will be nourished

  22. 4. Uterine Lining: • Thickens every month in preparation for fertilized egg

  23. 5. Cervix: • Muscular opening to the uterus

  24. Vagina: • Female internal reproductive organ • Also known as the birth canal
