How Does Viagra Work In the Body?

Viagra is the erectile dysfunction pill that helps the male taking obtain an erection when they become aroused, not the entire time the medication is in the system and working. This medication is able to do this by relaxing the smooth muscle of the penis and opening the arteries to allow blood flow when the man become aroused, just as it would occur naturally.

The first reaction is the brain sends a signal to certain nerve fiber, this fiber ends in the NANC nerve cell, which is in an artery in the area where blood needs to flow. The NANC nerve endings then inject nitric oxide into the blood and surrounding cells, this stimulates an enzyme known as guanylate cyclase. This enzyme produces a chemical named cyclic guanosine nomophoshpate. This natural reaction that is caused by arousal carries the right amount of blood flow that is needed to obtain an erection just as it occurs for any male.

This is where Viagra is able to help by opening the arties that carry the blood flow when the male is aroused.
