Danni & Caasi The Reproductive System
Overall function of system:
· For males – produce and maintain sperm cells. Components of the male reproductive system transfer sperm cells into the female reproductive system.
· For females – organs produce and maintain female sex cells, receive sperm cells, and transport the sperm cells and oocytes within the female system. Also supports the development of embryos and fetuses, and provides the passageway by which the fetus leaves the prenatal environment.
List of all Organs:
· Male –
o Penis = copulatory organ
o Bladder = collects urine execreted by the kidneys
o Vas deferens = sperm duct
o Prostate = secretes slightly acidic fluid that contains 20-30% of semen.
o Corpus cavernosum = one of a pair of sponge-like regions that that contains most of the blood in the penis during penile erections.
o Corpus spongiosum = prevents the urethra from pinching closed, maintaining the urethra as the exit path.
o Urethra = exit path for both urine and semen
o Seminal vesicle = secretes fluid that becomes the semen.
o Bulbourethral gland = glands produce a clear, slippery fluid that empties directly into the urethra. It produces substances related to nourishment of sperm
o Scrotum = pouch-like structure behind the penis that holds and protects the testes.
o Epididymis = coiled tubules found within the scrotum that store sperm. Also the site of their final maturation.
o Testis = produce sperm cells and secretes the testosterone
o Prepuce = foreskin; covers and protects the penis
· Female –
o Fallpoian tube = two thin tubes leading from the ovaries to uterus. Track for released egg.
o Ovary = the primary female reproductive organ; produces oocytes
o uterus = holds fetus
o endometrium = lining for the uterus
o cervix = opening to allow sperm and menstrual fluid to flow through
o bladder = collects urine execreted by the kidneys
o urethra = exit path for urine
o clitoris = pleasure
o labia minora = inner skin of the genitals
o labia majora = outer skin of the genitals
o vagina = tubular organ that leads from the uterus to the vestibule of the reproductive tract
Disorders & Diseases
· Endometriosis - condition where cells from the lining of the uterus appear outside of the uterine cavity
· Ovarian Cancer – cancer in the ovaries
· Premature Birth – baby comes early
· Testicular Cancer – cancer in the testicles
