Relate the Pulse to Heartbeat

AIM

The purpose of this project is to take your pulse at mutliple sites. Relate the pulse to heartbeat. The pulse represents the beating of the heart, specifically the ejection of blood from the left ventricle to the general circulation of the body. The ventricles (right and left) have two phases: diastole or the time when the ventricles 'rest' so they can fill with blood, and systole, the time when the ventricles contract to send blood either to the lungs (from the right side of the heart), or to the rest of the body (from the left side of the heart). Blood from the left side of the heart first enters the aorta, the largest artery in the body. The aorta branches into smaller arteries which carry blood to all part of the body.
