The amount of blood in the penis increases sixfold during an erection. The blood filling the corpora cavernosa compresses and then closes off the openings to the veins that normally drain blood away from the penis (see Figure 4). In essence, the blood becomes trapped, maintaining the erection.
Erectile tissue exists in places such as the corpora cavernosa of the penis, and in the clitoris or in the bulbs of vestibule. During erection, the corpora cavernosa will become engorged with arterial blood, a process called tumescence.
