The human heart is made of mesoderm. It is made up of four chambers upper part is right and left atrium and the lower are the right and left ventricles. The right atrium collects the deoxygenated from the body parts and passes it to right ventricles from there the blood moves to lunges and gets oxygenated. The oxygenated blood moves to the left atrium and from their passes to left ventricle from were the blood is distributed to the whole body through arota , arteries , veins and capillaries ..there are many valves present in the chambers , trunks to guide the direction of blood.
