  1. Reproduction

  2. Reproduction - All living things Reproduce - Unlike other body systems it's not essential to sustaining the individual’s life - Two sex cells, from two different people, meet to combine genetic material and create a new life

  3. Function - of any reproductive system - Procreation (Making babies)

  4. Puberty - The changing and developing of the body So what causes this change? Hormones

  5. Hormones - Chemical Messengers (Endocrine System) Functions: - Formation of primary sexual characteristics (During Development) - Activates and promotes secondary sexual characteristics (During Puberty)

  6. TheMale(XY) Reproductive System

  7. Function - Male - Procreation (Making babies)

  8. Hormones - Male - Chemical Messengers The primary Male hormone is: Testosterone What does it do: 1. During development – Primary sexual traits 2. During puberty – Secondary sexual traits

  9. Secondary Sexual Characteristics - Male Facial, pubic, & underarm hair 1. Shoulders broaden 2. Deepened voice 3. Muscle development 4. Sperm production 5.

  10. Structuresof the Male Reproductive System

  11. Diagramof the Male Reproductive System

  12. Name:________________ Word Bank: Bladder Epididymis Penis Prostate Scrotum Seminal Vesicle Testicle Urethra Vas Deferens

  13. Structures - Male Testes - (Testicles) Male sex glands that produce sperm and testosterone 1. Scrotum - Sack of skin that holds testes outside of the body 2. • This helps maintain optimal temperature

  14. Structures - Male Epididymis 3. - Located on the outer surface of each testicle - Temporarily stores Sperm; so that they can mature

  15. Structures - Male Vas Deferens 4. - Tube that extends from each Epididymis, around the bladder, until it. . . - Connects with the Urethra - It is about 18 inches Long

  16. Structures - Male Seminal Vesicles 5. - Two glands at the Base of Bladder - Attached to the Vas Deferens - Makes the fluid component of Semen – Like the part of blood Plasma

  17. Structures - Male Prostate 6. - A small gland - Surrounds a section of the Urethra - Produces a secretion to help sperm travel/survive

  18. Structures - Male Cowper’s Gland 7. - A small gland - Below the Prostate Gland - Produces a secretion to help sperm travel/survive

  19. Structures - Male Urethra 8. - A small tube that carries Urine and Semen - Extends from the Bladder through the Penis to the outside of the body

  20. Structures - Male Penis 9. - The external organ – for delivery - Composed of spongy tissue and blood vessels - Increased blood flow causes an Erection

  21. Structures - Male Foreskin 10. - Skin covering the tip of the penis - Circumcision - The surgical removal of the foreskin

  22. Semen A mixture of fluids/components: Sperm (spermatozoa) - The male sex cell that contains the genetic information Seminal Vesicle Fluid - Fluid that makes up about 70% of semen - Like the part of blood Plasma Prostate Fluid - 30-35% of the semen. Alkaline to counter the Vagina’s acidity Cowper’s Fluid - 5% of semen. Makes the environment of the urethra more hospitable

  23. A Sperm

  24. Problems of the Male Reproductive System

  25. Problems - Male Hernia - Abnormal exit of a tissue or organ through the wall of the cavity in which it normally resides - Most common in the abdomen - Abdominal muscle tears

  26. Problems - Male Inguinal Hernia 1. - Weak spot in the abdominal wall - Located just above the scrotum - Abdominal muscle tears - Intestines push into the scrotum

  27. Problems - Male - Condition in which a person is unable to reproduce Sterility 2. Causes: Just write down a couple - - STD’s Low sperm count - - Smoking/Drugs Temperature change - - Malfunctioning of reproductive structures Exposure to chemicals - Certain illnesses

  28. Problems - Male Enlarged Prostate 3. - Difficulty urinating, inability to completely empty the bladder, and chances of a UTI increase. Causes: - Old age - Infection - Tumors/Cancer

  29. Problems - Male Prostate Cancer 4. - Usually in older men - Highest type of Cancer in Males - Early Detection (by a Doctor) is Important Treatments: - Radiation - Surgical Removal of Prostate

  30. Problems - Male Testicular Cancer 5. - Usually males Ages 15 - 34 Could present as: Treatments: - Slight Enlargement - - Radiation Painless Lump - - Surgery/Removal Hardening of Testes - Pain in Testicle

  31. Care of the Male Reproductive System

  32. Care - Male Cleanliness 1. Protection 2. Practice Safe-Sex 3. - When the time comes Avoid contaminants 4. - Unhealthy food, pollutants, drugs Self-examination 5.

  33. TheFemale(XX)Reproductive System

  34. Function - Female - Procreation (Making babies) - Nourishment and protection (of the baby)

  35. Hormones - Female - Chemical Messengers The primary Female hormone is: Estrogen What does it do: 1. During development – Primary sexual traits 2. During puberty – Secondary sexual traits

  36. Secondary Sexual Characteristics - Female Breast development 1. Pubic and underarm hair 2. Hips widen 3. Menstruation begins 4.

  37. Structures of the FeMale Reproductive System

  38. Diagram of the FeMale Reproductive System

  39. Word Bank: Cervix Fallopian Tube Ovary Uterus Vagina

  40. Structures - Female Ovaries 1. - Female sex gland - Produce and house the Ova (Egg) - Produce Estrogen & Progesterone - Almond sized - Located on each side of the lower abdomen.

  41. Structures - Female Ova (Egg) 2. - Females are BORN with about 1 million ovum (No more eggs are made) - Females releases 1 ova/month - Ovulation

  42. Structures - Female Fallopian Tube 3. 1 3 __ - 4” Long & ” diameter - Ova move through Fallopian Tube to the Uterus - Waving motion draws the Ovum into the Fallopian Tube

  43. Structures - Female Uterus 4. - Small muscular organ - Vast supply of capillaries - If fertilization has occurred. . . - The Zygote attaches to the wall - Zygote = the joined egg/sperm

  44. Structures - Female Cervix 5. - Bottom of the Uterus - A doorway to the Vagina - Dilates during child birth - To allow passage of the baby

  45. Structures - Female Vagina 6. - The Birth Canal 1 2 __ - A muscular tube about 3 ” long - Connection of the Uterus to the outside of the body

  46. Structures - Female Vulva 7. - Encompassing name for all of the external parts - Folds of the vaginal entrance - Labia Minora – Inner Folds - Labia Majora – Outer Folds

  47. Fertilization

  48. Fertilization (Your notes are a little off for this section) - A Sperm is present while Ovum is in the Fallopian Tube - One Sperm unites with one Ova (egg) to form a Zygote - Cell Division begins and perpetuates - After 3-4 days, the Zygote moves to Uterus

  49. Menstruation
