Document Summary
Is the only system that is not essential to the life of the individual. The male and female reproductive organs produce and store specialized reproductive cells that combine to form new individuals. Reproductive organs also secrete hormones that play major roles in the maintenance of normal sexual function. Gonads- are organs that produce gametes and hormones. Includes all chambers and passageways that connect ducts to the exterior of the body. Male produces large quantities of gametes: produces billion sperm per day. Female produces one gamete per month: retains and nurtures zygote. Release one immature gamete (oocyte) per month. Carry oocytes to uterus- if sperm reaches oocyte, fertilization is initiated and oocyte matures into ovum. Testes form inside body cavity adjacent to kidneys. Locks testes in position (near anterior abdominal wall) as fetus grows. Circulating hormones: stimulate contraction of gubernaculum testis. Form body of spermatic cord: ductus deferens, testicular blood vessels, nerves, and lymphatic vessels.
