Which of the four chambers of the human heart pumps deoxygenated blood to the lungs?

The human heart is a powerful organ—one of the most powerful in the entire body! As the heart beats, it delivers oxygen-rich blood to the entire body. There are four chambers in the heart that together function as a two-sided pump. The left side of the heart pumps blood out into the body through the arteries, while the right side of the heart collects blood through the veins. The top chambers of the heart are called the left atrium and right atrium. The bottom chambers of the heart are the left ventricle and right ventricle, which have thicker walls.

The right atrium receives blood from the veins that has already circulated through the body which is low in oxygen and pumps it over to the right ventricle.

The right ventricle passes the deoxygenated blood on to the pulmonary artery, which sends it to the lungs to pick up oxygen.

The left atrium receives the now oxygen-rich blood from the lungs and pumps it into the left ventricle.

The left ventricle pumps the oxygen-rich blood to the body through a large network of arteries. The contractions of the left ventricle, the strongest of the four chambers, are what create blood pressure in the body.
