Reproductive System Notes see transparancy
Male Reproductive System: produces sperm and hormone testosterone; consists of testes, scrotum, penis. Testes: organ that produces sperm and testosterone (which controls male physical characteristics). Scrotum: external pouch containing testes. Semen: mixture of sperm cells and fluids. Penis: male sex organ; contains end of urethra where urine/semen leave the body.

Female Reproductive System: produces eggs and hormones estrogen, progesterone; consists of the ovaries, fallopian tubes, uterus, vagina. Ovaries: produce egg cells and estrogen (which controls some female characteristics) and progesterone. Fallopian tube: connects ovary (egg) to uterus; where fertilization occurs. Each month, one of the ovaries releases an egg. Uterus (womb): hollow muscular organ; the zygote develops (embryo,fetus,newborn) in the uterus Vagina: opening between uterus and outside body.

Reproductive System Notes
Sexual Reproduction (= Meiosis). The gametes are: Egg: female sex cell (= 23 chromosomes) Sperm: male sex cell (= 23 chromosomes) Fertilization: joining of sperm and egg Zygote: fertilized egg (= 46 chromosomes) Note: zygote undergoes cell division (= Mitosis): zygote → embryo → fetus → newborn (birth). Chromosome: X-shaped structure in cell’s nucleus contains units called genes which carries genetic information (inherited traits).

Menstrual Cycle: monthly cycle of change consisting of egg development in ovary and uterus prepares for arrival of embryo. Beginning: development of mature egg; uterus thickens Midway: egg released from ovary into fallopian tube (= ovulation); where fertilization occurs. If no fertilization, menstruation (“period”) occurs. Menstruation: blood, unfertilized egg, uterus’s tissue lining leaves body through vagina.
