the function what is divided into four Chambers of the left side contains the pure blood where is the right side contains the impure blood pure blood means oxygenated blood which is rich in oxygen and NP of blood which is the oxygenated blood rich in carbon dioxide and Nitrogen Oxygen so there are four Chambers is left Atrium and left ventricle light right Atrium and right ventricle

the main function of the heart stroke pump blood through the outer to all the parts of the body and to the power to take the deoxygenated blood from the lungs with the lungs and and then the process of oxygen it takes place in the heart and then prove the outer the oxygenated blood is transferred to all the parts of the body and the heart is responsible for the pumping of the blood

Arterial blood (red,O2 rich blood) flows from heart to each part of the body to provide oxygen and nutrients. Venus blood (blue, O2poor blood) returns from the body to the heart. The blood then travels through the lungs to exchange carbon dioxide for new oxygen. The heart is a pump which moves the blood. Hope it helps

The Heart is a pumping organ that receives blood from veins and pumps it into arteries.

Functions of Heart are:

1. To pump blood across the body.

There is only one function of Heart but this one function is the most important one in our whole body

Heart is a conical muscular double pump structure that brings about circulation of blood in the body. There are four chambers.

Deoxygenated blood from the whole body enters right auricle through a superior vena cava (from upper parts of the body), inferior vena cava (from middle and lower parts of the body) and coronary sinus (from the walls of the heart). Oxygenated blood is carried by pulmonary veins into left auricle from lungs. On being filled, the two auricles contract simultaneously and pass their bloods into ventricles, deoxygenated in right ventricle and oxygenated in left ventricle. The distended ventricles now undergo contraction or systole forcefully. Right ventricle passes blood to pulmonary arch which divides to form pulmonary arteries. Pulmonary arteries take the deoxygenated blood to lungs. Left ventricle passes blood to aorta that supplies oxygenated blood to all parts of the body.
