By Sabine Walter, Pierre A. Knowing how a penis functions can provide useful insight into sex and the human body — whether you want to understand the penis and male anatomy better or learning about it for the first time. Basically, a penis is composed of three structures, which are made of a spongelike material that can fill with blood:. The two corpus cavernosa contain the central arteries and lie on the top half of the penis. They are cylindrical tubes and are larger than the other spongy structure. The corpus spongiosum , which is under the two corpus cavernosa and surrounds the urethra, is the pipeline for both urine and sperm. When a man becomes sexually excited , the nerves surrounding his penis become active, causing the muscles around the arteries to relax and more blood to flow into the penis.

The human penis is an external male intromittent organ that additionally serves as the urinal duct. The main parts are the root radix ; the body corpus ; and the epithelium of the penis including the shaft skin and the foreskin prepuce covering the glans penis. The body of the penis is made up of three columns of tissue : two corpora cavernosa on the dorsal side and corpus spongiosum between them on the ventral side. The human male urethra passes through the prostate gland , where it is joined by the ejaculatory duct , and then through the penis. It is a passage both for urination and ejaculation of semen.
