Erectile tissue

Erectile tissue is tissue in the body with numerous vascular spaces, or cavernous tissue, that may become engorged with blood. Erectile tissue exists in places such as the corpora cavernosa of the penis, and in the clitoris. During erection, the corpora cavernosa will become engorged with arterial blood, a process called tumescence. This may result from any of various physiological stimuli, also known as sexual arousal.
