Human reproduction powerpoint

  1. 1. Human Reproductive System
  2. 2. Male Reproductive Organs
  3. 3. Male External Reproductive Organs 1. Penis The organ used to transfer urine, sperm and semen. Also contains the Urethra. 2. Scrotum The sac around the testicles. A muscular tissue that holds the testes to suspend them away from the body.
  4. 4. Male Internal Reproductive Organs 1. Testicles Two sex glands that produce the male reproductive cells called sperm and the male hormone testosterone. Composed of hundreds of tiny tubes. Called “seminiferous tubules” 2. Epididymis The place where sperm are stored until they ripen and mature. Connects seminiferous tubules in the testes to the vas deferens.
  5. 5. Male Internal Reproductive Organs 3. Vas deferens The passageway carrying the sperm from the epididymis to the seminal vesicles. 4. Seminal Vesicles Produces a sticky, sugary fluid to nourish the sperm. 5. Prostate Gland A donut shaped gland that surrounds the urethra and produces liquid that adds to the semen and hormones. (protects and enriches sperm)
  6. 6. Male Internal Reproductive Organs 6. Cowper’s Gland Two small glands that secrete a clear sticky fluid to help neutralize the acidity of the urethra. 7. Urethra The passageway to transfer urine or semen outside the body.

  9. 9. Female Reproductive Organs
  10. 10. Female External Reproductive Organs 1. Labia Outer and inner lips protecting against germ entry through the vagina. 2. Vulva All sexual parts located outside the body.
  11. 11. Female Internal Reproductive Organs 1. Vagina Passageway from outside the body to the cervix for sperm, menstrual fluid, and birth canal. 2. Cervix The lower end of the uterus, a neck like part attached to the vagina.
  12. 12. Female Internal Reproductive Organs 3. Uterus Also called the womb. Hollow, expandable muscle where the baby grows.
  13. 13. Female Internal Reproductive Organs 4. Endometrium Inner lining of the uterus
  14. 14. Female Internal Reproductive Organs 5. Menstruation Sloughing off of the endometrium (blood & tissue). Occurs when ovum is not fertilized.
  15. 15. Female Internal Reproductive Organs 6. Fallopian Tubes On both sides of the uterus, connects ovaries to uterus. Fertilization takes place here. 7. Fimbrae Fingerlike structures meant to sweep the ovum into the fallopian tube.
  16. 16. Female Internal Reproductive Organs 8. Ovaries Two almond shaped sex glands located on each side of the uterus. The ovum matures here, and the sex hormones estrogen is produced here.
  17. 17. Non Reproductive Parts In Pelvic Area 1. Perineum Area between the rectum and the vagina.

  20. 20. Male Reproductive System 
  21. 21. Female Reproductive System 
  22. 22. Caring for the Male System      Practice good Hygiene  Bathe regularly and thoroughly clean the penis and scrotum. (Under the foreskin) Wear protective equipment  Cup or other support Practice Abstinence to avoid STD’s Regular Self Exams  Check Get Regular Check ups every 12-18 months
  23. 23. Testicular Self Exam    1. Stand in front of a mirror and look for swelling. Roll the testicle between thumb and forefingers. 2. Cancerous lumps are usually found on the side but can be found on the front. Find the epididymis so you don’t mistake it for a lump (a soft tube like structure behind the testicle.) 3. Most lumps are not cancerous, but if you do find one see a health care professional.
  24. 24. Caring for the Female System  Bathe Regularly  Change tampons and pads every few hours  Get regular medical Exams  Practice Abstinence to avoid STD’s  Perform Self Exams
  25. 25. Breast Self Exam 1. 2. 3. 4. Lie down with a pillow under your right shoulder. Put your right shoulder under your head. Place the three middle fingers of your left hand on your right breast. Rub in a circular motion with light, medium, and then firm pressure. Go in a zig zag motion up and down. Repeat on the other side. Look in a mirror for changes, rashes, dimpling, scaliness or discharge from the nipple. Raise your arms, palms together and look for changes. Examine your underarms.
  26. 26. 4 Stages of The Menstrual Cycle Days 1-5 Menstruation Lining of uterus is shed Days 6-9 Lining of the uterus is very thin
  27. 27. 4 Stages of The Menstrual Cycle Days 10-14 Lining of uterus thickens Days 15-28 Lining of the uterus is ready to receive a fertilized egg.
  28. 28. Conception 1. Ovulation The ovum is released from the ovary.
  29. 29. Conception 2. After being released, the ovum travels through the fallopian tube and enters the uterus.
  30. 30. Conception 3. Fertilization takes place when the sperm penetrates the ovum.
  31. 31. Conception 4. Fertilization normally takes place in the fallopian tube. 5. Only one sperm can penetrate an ovum.
  32. 32. Conception 6. If more than one ovum is present, both may be fertilized.
  33. 33. Conception 7. The fertilized cell implants in the uterine lining.
