What type of tissue becomes turgid when flooded with blood, causing an erection?

Erectile tissue is the correct answer because it is specifically designed to fill with blood, leading to an increase in size and rigidity, which results in an erection. This tissue is found in the penis and is composed of a network of blood vessels and spaces that can expand. When stimulated, the blood vessels dilate, allowing more blood to flow into the erectile tissue, thereby causing it to become turgid.

In contrast, while muscle tissue plays a role in various bodily functions, it does not specifically become turgid in response to blood flow. Similarly, connective tissue provides structural support but does not have the ability to fill with blood like erectile tissue. Nervous tissue is responsible for transmitting signals within the body but does not directly contribute to the physical process of erection. Therefore, erectile tissue is uniquely suited for this function due to its capacity to engorge with blood.
