The heart, as a vital component of the circulatory system, is primarily in charge of pumping blood and distributing oxygen and nutrients throughout the body. Because of this function, the heart is one of the most important and complex organs in the body, with even minor dysfunctions or abnormalities causing drastic changes or effects in the human organism.
The heart is a muscle, and its operation is made possible by the many parts that work together. The organ is divided into chambers that take in and distribute either oxygen-depleted or oxygen-rich blood. These chambers are accompanied by veins and arteries, which serve the same purpose. The heart successfully pumps blood with ease because all of its parts work together toward the same goal.
A healthy adult heart can normally go through three cardiac cycles or 72 beats per minute; however, this rate changes for children, whose heart rates are normally and relatively faster.
The heart's structure
The heart is located in the center of the chest, beneath the sternum in a thoracic compartment.
It is made up of four chambers and several valves that control the normal flow of blood throughout the body.
The upper portion of the heart is divided into two chambers called atria, with the left atrium receiving oxygen-rich blood and the right atrium receiving oxygen-free blood.
The valves that separate these chambers are called atrioventricular valves, composed of the tricuspid valve on the left and the mitral valve on the right.
