FEMALE REPRODUCTIVE SYSTEM The female reproductive system enables a woman to: produce eggs (ova) have sexual intercourse protect and nourish the fertilized egg until it is fully developed give birth

FEMALE REPRODUCTIVE SYSTEM Ovaries: 2 ovaries – produce, store, and release eggs—produce estrogen Fallopian tubes: go from the ovaries to the uterus – “highway” Uterus: a hollow, pear shaped organ with a muscular wall – where a fetus, or baby, grows Cervix: the lower part of the uterus that opens into the vagina Vagina: a tube that connects the uterus to the outside of the body. The entrance to the vagina is on the outside of the body.

FEMALE REPRODUCTIVE SYSTEM Ovulation: when an egg is released from an ovary into the fallopian tube – occurs once a month Fertilization: when an egg and a sperm unite Menstruation: "period" -- 2 to 7 days -- blood and tissue leave the body through the vagina Why? Each month, blood and tissue build up in the uterus to prepare for a fertilized egg in case a woman becomes pregnant. If the egg isn't fertilized, that lining leaves the body through the vagina and the girl has her period.

MALE REPRODUCTIVE SYSTEM Unlike the female, whose sex organs are located entirely within the pelvis, the male has reproductive organs that are both inside and outside the pelvis. The male genitals include: the testicles the duct system, which is made up of the epididymis and the vas deferens the accessory glands, which include the seminal vesicles and prostate gland the penis

MALE REPRODUCTIVE SYSTEM Testicles or testes: 2 testicles – produce sperm—produce testosterone Epididymis: where sperm is stored Vas deferens: transports the sperm from the epididymis to the urethra – “highway”

MALE REPRODUCTIVE SYSTEM Urethra: the tube that carries semen and urine out of the penis Semen is a thick fluid that contains sperm Seminal vesicles: secrete a thick fluid that nourishes the sperm Prostate gland: walnut‑sized gland -- produces some of the fluid in semen

MALE REPRODUCTIVE SYSTEM Scrotum: hangs under the penis and contains the testicles and epididymis – regulates the temperature of the sperm Penis: made of two parts -- the shaft (the main part) and the glans (the tip, sometimes called the head).
