Introduction to heart
The heart is a muscle, which performs the job to pump blood around the body through a network of arteries and veins. Arteries carry oxygenated blood and distribute it to different parts of the body, while the veins receive deoxygenated blood from the parts of the body and take it back to the heart.
The heart contains both the oxygenated and deoxygenated blood. The right chamber of the heart receives deoxygenated blood through veins, which then goes to the lungs to become oxygenated. This oxygenated blood comes back to the heart from where it is distributed to all the parts of the body through the arteries. In this manner, every cell of the body is able to get oxygen.
