Penis

Penis is another name for the penis and, together with the scrotum, is one of the external male sex organs. The penis consists of the shaft and the glans. The glans is the most sensitive part of the male body and is covered by a foreskin, unless the person is circumcised. The urethra runs through the penis, through which not only urine but also seminal fluid passes. Three cavernous bodies in the penis can fill with blood during sexual arousal, making it firmer, larger and erect (see erection).
