For an erection, the most important part is the Corpora Cavernosa. These are two cavities that run the length of your penis and actually fill with blood to create an erection. Basically, the penis is a "hydraulic" machine.
The glans penis (or simply glans) is the sensitive bulbous part the end of the penis, opposite of the base. This is commonly referred to as the "head" of the penis. When the penis is flaccid, the glans is covered by the foreskin, unless the individual is circumcised.
The uretrha is a tube that connects the bladder to the outside of the body, allowing urine to exit the body. In males, the urethra also allows for semen to be passed.
The corpus spongiosumndis is the mass of spongy tissue surrounding the male urethra within the penis.
