Hydraulics

4. A) The heart isn't an actual hydraulic system. It utilizes blood under pressure, valves, and acts like a pump. These are all parts of a hydraulic system. B) Diastole is when your heart expands and systole is when it contracts. C) A normal blood pressure is between 70 and 80 D) when you have high blood pressure for long periods of time you could have a heart attack or arrhythmia(irregular heart beat). You could also get a blood clot. E) Blood moves up your leg because of the blood pushing it from behind (get it?) The heart puping more blood through moves the blood up your leg.
