[|heart animation]


 * Four chambers of the heart
 * 2 atrium
 * 2 ventricle
 * Blue side is right red side is left
 * Atriums on top
 * Ventricle on bottom
 * Veins bring blood to the heart
 * Arteries take blood away
 * Blue blood does not have oxygen
 * first blue blood goes to the right atrium...when heart is relaxed it goes into the ventricle when heart relaxes it goes out of the ventricle
 * from right atrium to left ventricle
 * Then that blood goes to collect oxygen in the lungs when the heart contracts
 * then blood that had been in the lungs goes into the left atrium then it goes into the left ventricle when it contracts it is sent back into the body
 * Pulse is feeling an artery every time the heart contracts
 * Lub dub is hearing the valves open and close dub is louder because it is pushing blood out to go through the entire body
 * Blood pressure how much pressure is in your blood..systole pressure of blood after heart contracts...diastole-how much pressure is in the blood when it relaxes
