What is blood pressure?

ANSWER

Blood pressure is the measure of the force of blood pushing against blood vessel walls. The heart pumps blood into the arteries, which carry the blood throughout the body. High blood pressure, also called hypertension, is dangerous because it makes the heart work harder to pump blood out to the body and contributes to hardening of the arteries (atherosclerosis), stroke, kidney disease, and the development of heart failure.
