Study Notes
Sexual Reproduction
- Involves a male sperm fertilizing a female egg, creating offspring.
- Males produce sperm in the testicles.
- Females develop eggs in the ovaries.
- The union of sperm and egg is called a zygote.
- Internal fertilization occurs when sperm fertilizes the egg inside the female's body.
- External fertilization occurs when the sperm and egg unite outside the female's body (e.g., fish).
Asexual Reproduction
- Offspring are created without a male partner.
- Asexual reproduction creates a copy of the parent's DNA in a new cell.
- Budding: a new cell grows on the parent cell and detachs when fully developed.
- Splitting: an organism splits down the center to create two identical organisms.
- Pathogenesis: The organism reproduces with itself creating a clone if no mate is available.
Male Reproductive System
- Bladder: Stores urine.
- Seminal vesicles: Two pouches at the base of the bladder producing a fluid high in fructose and sugars to nourish sperm (and also protein and enzymes).
- Prostate gland: A small organ contributing to semen production during ejaculation.
- Epididymis: Stores sperm and transports it to the sperm duct.
- Sperm duct (vas deferens): Transports sperm from the epididymis to the urethra.
- Urethra: Tube that allows urine and semen to exit the body.
- Anus: Exit point for solid waste.
- Testicles: Produce sperm and testosterone.
Female Reproductive System
- Fallopian tubes: Transport eggs from the ovaries to the uterus.
- Ovaries: Produce eggs.
- Cervix: Narrow opening of the uterus; prevents bacteria entry but allows sperm passage.
- Vagina: Passageway for menstrual blood exit and sperm entry.
- Bladder: Stores urine.
- Urethra: Tube allowing urine to exit the body.
- Clitoris: A pleasure center.
- Vulva: External flaps protecting the vagina.
- Hymen: Membrane partially covering the vagina opening (variable).
Menstrual Cycle
- Day 1-6 (menstruation): Uterus lining sheds if egg is not fertilized. This lasts 2-5 days.
- Day 6-10 (lining regrowth): Uterus lining rebuilds in preparation for pregnancy.
- Day 10-14 (ovulation): Egg is released from the ovary.
- Day 15-28 (lining thickening): Uterus lining thickens to prepare for a possible pregnancy.
- Cycle starts again at day 1. If egg isn't fertilized, the uterine lining sheds again.
Additional Reproductive Terms
- Scrotum: Protective sac holding the testicles.
