Definition
Erectile tissue is a specialized type of tissue capable of swelling with blood, causing an organ to become erect. Think of it like a sponge that fills with water. It's found in the penis, clitoris, and nipples. This tissue contains numerous blood vessels and sinuses that can expand when filled with blood. The expansion is controlled by the nervous system. Erectile tissue allows for sexual arousal and nipple sensitivity. Imagine it as the body's way of preparing for intimacy and pleasure.
