101 Diagrams of Heart

Learning about human’s body anatomy is always exciting and amazing. One of the most important organ of human’s body is the heart. It is a muscular organ about the size of a closed fist that functions as the body’s circulatory pump. It takes in deoxygenated blood through the veins and delivers it to the lungs for oxygenation before pumping it into the various arteries (which provide oxygen and nutrients to body tissues by transporting the blood throughout the body). The heart is located in the thoracic cavity medial to the lungs and posterior to the sternum. And when you’re talking about anatomy of human body, we can’t leave out the function of a diagram, and here it is for a handy of diagram of heart for you to print!

Cited from www.webmd.com,the heart has four chambers: the right atrium receives blood from the veins and pumps it to the right ventricle; the right ventricle receives blood from the right atrium and pumps it to the lungs, where it is loaded with oxygen; the left atrium receives oxygenated blood from the lungs and pumps it to the left ventricle; the left ventricle (the strongest chamber) pumps oxygen-rich blood to the rest of the body. The left ventricle’s vigorous contractions create our blood pressure.

Seeing this, now you know why your heart, blood vessels and blood itself are three essential components the body needs to survive. The circulatory system consists of two circuits that blood travels through; pulmonary and systemic. Exercise affects these systems, causing the heart to pump blood faster around the body, which in turn allows you to exercise for longer! You know to what extent you can exercise for the sake of your heart’s health!
