How an Erection Works72
When aroused, the nerves surrounding the penis become active. The muscles around the arteries relax and more blood flows into the penis.
This additional blood makes the penis stiff and hard, or erect. The erection tightens the veins so the blood can’t leave the penis, enabling the penis to remain erect.
