The heart is the most important muscle in the human body. It is located in the circulatory system and it pumps blood along with other nutrients all through the body, which in turn keeps us alive. But, what is actually happening when it beats? Simultaneously, the heart is receiving deoxygenated blood and returning oxygenated blood to the body. It is made up of four chambers called the left and right atria, located on top, and the left and right ventricles, located on the bottom. The right atrium fills with blood from the veins and then contracts to send the blood to the right ventricle, which then sends oxygen rich blood to the lungs through arteries. At the same time, the left atrium fills with blood from the veins and then contracts sending blood to the left ventricle, which then sends blood to the rest of the body through arteries (Silverthorn). A pulse happens every time the heart contracts. Pulse in counted by the number of times an artery expands and contracts as a result of the heart beating. It is measured in number of beats per minute and is commonly written as bpm. There are seven arteries in the body used to measure pulse, here are a few: the radial artery, located on the thumb-side of the wrist; the brachial artery, located on the inside of the arm at the elbow; and the carotid artery, located on the side of the neck (Silverthorn).
