Document Summary
The reproductive system does not take part in homeostasis. Epididymis sperm storage & site of maturation (i. e. increase i metabolic function. Holds the testes, and there are muscles which moves the testes up or down to adjust the temperature. Has smooth muscle contractions during ejaculation to facilitate movement of sperm towards and out of urethra. Seminal vesicles, prostate gland, and bulbourethral glands (accessory glands) give out 90% of secretions contributing to the make-up of semen. Sperm only makes up 10% of semen: urethra a common passage for sperm and urine. Semenogelin coagulation to keep sperm together when travelling through the uterus. Prostaglandins smooth muscle contraction in female reproductive tract to propel sperm. Clot disruption for when the sperm gets close to the cervix (must enter one at a time) Testes are comprised of epididymis & seminiferous tubules (site of spermatogenesis) Seminiferous tubules walls contain sertoli cells and spermatogonia (spermatogenesis)
