The heart is responsible for pumping blood through your body. The heart is a muscle and is connected to the circulatory system as a means by which blood can flow through your body. The heart has four chambers, two atria and two ventricles. The atrias are receiving chambers and ventricles are discharging chambers. When blood enters into the left side of the heart, the first atria receives the deoxygenated blood from the body and takes the blood into the lungs where blood can then be oxygenised. The blood then comes back to the right side of the heart, which then takes the blood and pumps it out to your body through the body’s circulatory system.  The blood can then provide oxygen to your whole body. Blood also contains vital nutrients such as water and proteins, needed for your body to function and work properly. The repeated contraction of your heart (or ‘beating’) is the process by which the heart pumps blood. Blood then flows through your body like a current, eventually ending up back at the heart, which recycles the blood, re-oxygenating it, before sending it back out to provide sustenance to your body. Without a heart it would be impossible for humans to live. A human heart is roughly the size of an adult human fist and is located behind the rib cage, anterior to the vertebral column and posterior to the sternum. Advances in medicine have made it possible to maintain defective hearts with the use of a pacemaker. Pacemakers are artificial, manmade, electrical devices that use electrical impulses to mimic the beating of a heart, helping the heart to beat correctly to regulate blood flowing through a body. It is now possible for humans with defective hearts to live much longer with the use of a pacemaker.

Heart is actually a muscular organ. It is present in all vertebrates. It is made up of an involuntary muscle tissue that is found only in the heart. The human heart beats at a rate of 72 beats per minute and beats for around 2.5 million times during an average life time.

The main function of the heart is to pump blood through the blood vessels by repeated contractions. It collects de-oxygenated blood from the body and pumps it into the lungs. Here the carbon dioxide is cleaned off and oxygen is taken through diffusion. The heart is also responsible for collecting oxygenated blood from the lungs and pumping it to the entire body.

The heart can be defined as a pump whose sole purpose is to act as the driving force behind the circulation of blood throughout the human body. The heart is made up of cardiac muscles. These muscles are a kind of tissue unique to the heart and they are also what are known as involuntary muscles. The contraction and expansion of these muscles helps the heart pump oxygen rich blood throughout the body. At an average the human heart beats nearly a hundred thousand times every single day.

In one day it pumps around four thousand three hundred gallons of blood. In every human being the heart starts pumping when they are born and stops doing so only when they die, unless of course they have had a near death experience where the heart stopped.
