  3. The Male Reproductive System Bladder Spine Pelvic Bone Lymph Nodes Seminal vesicle Prostate gland Rectum Urethra Penis Sperm duct Testes Scrotum

  4. The Male Reproductive Vocab • Penis • Main organ through which sperm is released during sex • Testes • Glands that produces male sex hormones (testosterone) and male gametes (sperm) • Spermatozoa • Full name of sperm (male gametes) • Scrotum • Elastic skin sac that holds and protects the testes; keeps testes at 37oC • Spermduct • Tube that carries sperm to penis • Seminal vesicle and Prostrate gland • Release fluid and glucose to mix with sperm to create semen, which is released by the penis • Ejaculation • The release of semen from the penis during a male orgasm (feelings of pleasure during sex)

  5. The Female Reproductive System Spine Ovary Oviduct Endometrium Uterus Pelvic bone Cervix Bladder Rectum Urethra Vagina Clitoris

  6. The Female Reproductive Vocab • Vagina • Main organ through which the penis enters during sex • Ovary • Glands that produces male sex hormones (estrogen and progesterone) and female gametes (egg) • Ova • Actual name for egg (female gamete) • Oviduct • Tube that carries ova to uterus; site of fertilization • Endometrium • Lining of tissue and blood vessels on the walls of the uterus; site where fertilized eggs binds to uterus • Uterus • Womb; area where fertilized eggs (zygotes) develop into a fetus (unborn baby) • Cervix • Where the uterus meets the vagina; small opening to allow the uptake of sperm into the uterus • Clitoris • External node of nerve cells that helps with sex when stimulated

  7. The Female Reproductive System Oviducts Ovary Uterus Endometrium Cervix Vagina

  8. Male vs. Female Gametes • How are gametes produced? • meiosis • Where are sperm produced? • In the testes • Where are eggs produced? • In the ovaries • Sperm: • Head Nucleus (DNA) and enzyme (acrosome) which helps sperm enter egg • Middle full of mitochondria • Tail flagella to push forward • Egg: • Large round cell of cytoplasm, nucleus, and cell membrane • Jelly layer slows sperm entering egg
