Document Summary
Bladder: collects urine from the ureters for excretion. Ureters: carries urine by peristalsis from the kidneys to the bladder. Epididymis: a highly convoluted duct behind the testis, along which sperm passes to the vas deferens. Vas deferens: the duct that conveys sperm from the testicle to the urethra. Vasectomy: blocks or cuts each vas deferens tube, keeping sperm out of your semen. Penis: external male intromittent organ that additionally serves as the urinal duct. Scrotum: a pouch of skin containing the testicles. Os penis: a bone in the penis of carnivores and some other mammals. Urethra: the duct by which urine is conveyed out of the body from the bladder, and which in male vertebrates also conveys semen. Accessory sex glands: include the seminal vesicles, prostate, and bulbourethral glands. The secretion from each of these glands is added to the testicular fluid and forms a substantial part of the semen.
