Verified step by step guidance

Understand the anatomy of the clitoris and penis: Both organs are part of the external genitalia and play a role in sexual arousal and pleasure.

Learn about erectile tissue: Erectile tissue is a specialized type of tissue found in both the clitoris and penis. It contains vascular spaces that can fill with blood during arousal, leading to erection.

Explore the physiological mechanism of erection: During sexual arousal, signals from the nervous system cause blood vessels in the erectile tissue to dilate, increasing blood flow and trapping blood within the tissue. This process leads to the swelling and firmness characteristic of an erection.

Compare the structures: Both the clitoris and penis contain similar types of erectile tissue, such as the corpus cavernosum, which is responsible for the engorgement during arousal.

Clarify the incorrect options: The clitoris and penis are not directly connected to the ovaries, are not composed of cartilage, and do not secrete hormones to trigger erection. The correct answer is based on the presence of erectile tissue in both organs.
