What is the Reproductive System? A combination of body structures and organs that allow humans to make babies.

Key Point #1: Function To produce another of your own kind Chickens lay little chicks. Lambs have baby lambs. Goats have kids. Dolphins have little dolphins. Big trees have little plants.

Key Point #2: Sex Cells  Males: Sperm  Females: Eggs Female have a certain amount of eggs stored in the ovaries since birth!Female have a certain amount of eggs stored in the ovaries since birth! There are about 3,000 eggs!!!There are about 3,000 eggs!!! Men continue to produce new spermMen continue to produce new sperm cells throughout their entire life

Swimming for your life  A sperm is a tiny package with a big responsibility –  Key Point #3: sperm fertilize the egg and create human life  It takes ONE sperm to fertilize an egg  So that tiny package is loaded with “gear” for its important journey.  How many sperm does it take to fertilize an egg? A few facts:  Daily sperm production by a healthy man: 10 million to 50 million  Contents of average ejaculation: 200 million sperm; 120 million moving; 80 million deformed  Maturation: 72 days  Survival time in a woman: 2 to 7 days

Male Reproductive System 1. Scrotum 4. Prostate 5 Basic Parts 5. Urethra 6. Penis 2. Testicles (testes) 3. Vans Deferens

Male Reproductive System – Scrotum 1. Scrotum Contains the testesContains the testes Controls temperature for sperm productionControls temperature for sperm production

Male Reproductive System – Testes (testicles) 2. Testicles Produces spermProduces sperm

Male Reproductive System – Vans Deferens 3.Vans Deferens-3.Vans Deferens- Tube from testes to prostateTube from testes to prostate

Male Reproductive System – Prostate gland 4.Prostate gland -4.Prostate gland - makes semen that help sperm movemakes semen that help sperm move

Male Reproductive System – Urethra 5. Urethra -Connects bladder AND the vas deferens to the penis - carries urine OR sperm

Male Reproductive System – Penis 6. Penis Organ with muscleOrgan with muscle Pushes urine OR semen out of bodyPushes urine OR semen out of body

 What is a vasectomy?  The cutting of the Vans Deferens so sperm cannot travel to the prostate and out of the body. “Permenant” birth control. Quick Freeze

Female Reproductive System 5 Basic Parts

Female Reproductive System - Ovary 1.Ovary Stores and releases eggs There are two ovaries Female get a certain amount of eggs stored in the ovaries since birth!Female get a certain amount of eggs stored in the ovaries since birth! There are about 3,000 eggs!!!There are about 3,000 eggs!!!

Female Reproductive System – Fallopian Tube 2. Fallopian tube Pathway from the ovaries to the uterus Key Point #4: Fertilization takes place in the fallopian tube. Joining of egg and sperm

Female Reproductive System - Uterus 3. Uterus Fertilized egg grows here

Female Reproductive System - Cervix Cervix The “doorway” to the uterus Made of strong muscles that the baby passes through during delivery

Female Reproductive System - Vagina 4. Vagina Muscular path from uterus to the outside

Tell me what ya know!

 What is the tube that eggs travel through in order to reach the uterus  Fallopian Tubes Female Body System

 Woman have 2 of these…  They store and release eggs  Ovaries Female Body System

 Males produce this sex cell  Sperm Male Body System

 This organ produces sperm  Testes Male Body System

 This organ (tube) is responsible for expelling both urine and semen  Urethra Male Body System

 Key Point #5: A chemical released by a gland in one part of the body that affects another part of the body. Hormones

 TESTOSTERONE:  Responsible for the production of “male” characteristics Increased muscle mass Body hair Deepening of the voice  Allows men to produce sperm Male Sex Hormones

Female Sex Hormones  ESTROGEN:  the hormone responsible for secondary sex characteristics  The “egg producing” hormone.  PROGESTERONE:  builds up the lining of the uterus to prepare it for the fertilized ovum; the “egg-setting” hormone.
