Male and Female Reproductive Systems: Parts and Processes

Learn about the male and female reproductive systems, including the parts involved and the process of reproduction. Understand the functions of sex cells, fertilization, chromosomes, and the organs involved in reproduction. Discover the roles of hormones and the structures responsible for producing and releasing eggs.

Presentation Transcript

  1. TOPIC: ReproductionAIM: What are the parts of the male and female reproductive systems?

  2. Reproduction Process through which living things produce new individuals of the same kind

  3. What are sex cells? Gametes Sperm = male sex cells

  4. Eggs = female sex cells

  5. Fertilization Joining of a sperm cell with an egg to form a fertilized egg (ZYGOTE)

  6. Chromosomes Rod-like structures found in every cell Hereditary/genetic information 46 in each cell except in sex cells which have 23

  7. EGG + SPERM  ZYGOTE • 23 23 46 (NORMAL #) 23 + 46 23

  8. MALE REPRODUCTIVE SYSTEM

  9. Testes Male gonads Produces sperm & testosterone

  10. Scrotum = Sac of skin which holds testes • Keeps temp slightly cooler for sperm production

  11. Vas deferens Sperm duct Tube that carries sperm from testes to urethra

  12. Glands produce fluids that make up SEMEN (used to transport sperm)

  13. Penis Urethra male organ that transfers sperm into female tube that carries SPERM and URINE out of the body

  14. 9. Urinary bladder 4. Seminal vesicles 5. Prostate gland 10. rectum 6. Cowper’s gland 3. Vas deferens 7. urethra 8. penis 2. scrotum 1. testes

  15. REVIEW 1. In human males, sperm cells are suspended in a fluid medium. The main advantage gained from this adaptation is that the fluid  (1.) activates the egg nucleus so that it begins to divide  (2.) provides currents that propel the egg down the oviduct  (3.) removes polar bodies from the surface of the sperm  (4.) acts as a transport medium for sperm

  16. 2. In the human male, sperm leave the body through the ________________. 3. In the human male, gametes are produced in the ______________.

  17. FEMALE REPRODUCTIVE SYSTEM

  18. Ovaries Female gonads Produces eggs, estrogen & progesterone

  19. Follicles Tiny egg sacs in ovaries Each holds an immature egg Immature egg follicle

  20. Oviduct Fallopian tubes Carry egg to uterus Where FERTILIZATION occurs

  21. Uterus muscular organ where fetus develops CERVIX – lower end

  22. Vagina Birth canal Muscular tube that receives sperm from the male

  23. Ovulation Egg is released from the ovary & moves into oviduct

  24. 1. ovary 2. Oviduct / fallopian tube 8. rectum 3. uterus 4. cervix 7. Urinary bladder 6. Urethra 5. vagina

  25. Identify all labeled structures in the diagram. • In which structure will an embryo develop? • In which structure can an egg be fertilized? • Which structure produces and releases eggs? • What hormones does structure A secrete?
