Pulmonary artery (to the lungs) Aorta (to the rest of the body.)
The ventricles are the lower chambers of the heart. The atria are the upper chambers.
The lower chambers of the heart have a different function than the upper chambers. The lower chambers pump the blood out of the heart into the body and lungs.

A pulmonary artery is an artery in the pulmonary circulation that carries deoxygenated blood from the right side of the heart to the lungs. The largest pulmonary artery is the main pulmonary artery or pulmonary trunk from the heart, and the smallest ones are the arterioles, which lead to the capillaries that surround the pulmonary alveoli.
The heart has 4 chambers. The "collecting chamber of the heart", or the atria , is the two chambers that are located above the other two chambers. It carries the responsibility in helping to pump the blood out of the chambers and making sure no blood pumps back in.
