Hey mate ^_^

Answer:
=======

=> The heart pumps blood through the body.

=> Blood low in oxygen from the systemic circulation enters the right atrium from the superior and inferior venae cavae and passes to the right ventricle.

=> From here it is pumped into the pulmonary circulation, through the lungs where it receives oxygen and gives off carbon dioxide.

The strong muscular walls contract (squeeze),pumping blood to the rest of the body. on the surface of the heart,there are coronary arteries,which supply oxygen-rich blood to the heart muscles itself . .....The artria and ventricles work together ,contracting and relaxing to the pump blood out of the heart
