What is BP
when you heart
beats it pumps out a bunch of blood
into your arteries like into a hose.
The pressure rises in your hose depending on how full your hose is, how fast your hose drains and how elastic your hose is and how fast your heart squeezes the blood into your hose,. The peak prrssure during the squeeze is called the systolic BP top #, lowest pressure when not squeezing is diastolic bottom #
