   The heart is a muscular organ situated in the mediastinum.It consists of four chambers, four valves, two main arteries (the coronary arteries), and the conduction system. The left and right sides of the heart have different functions: the right side receives de-oxygenated blood through the superior and inferior venae cavae and pumps blood to the lungs through the pulmonary artery, and the left ...

   Diagram of the human heart showing blood oxygenation to the pulmonary and systemic circulation. The heart pumps blood to all parts of the body providing nutrients and oxygen to every cell, and removing waste products. The left heart pumps oxygenated blood returned from the lungs to the rest of the body in the systemic circulation.

   The systemic circulation then transports oxygen to the body and returns carbon dioxide and relatively deoxygenated blood to the heart for transfer to the lungs. [8] The right heart collects deoxygenated blood from two large veins, the superior and inferior venae cavae. Blood collects in the right and left atrium continuously. [8]

7. Lung - Wikipedia

   en.wikipedia.org/wiki/Lung

   The right lung is bigger than the left, and the left lung shares space in the chest with the heart. The lungs together weigh approximately 1.3 kilograms (2.9 lb), and the right is heavier. The lungs are part of the lower respiratory tract that begins at the trachea and branches into the bronchi and bronchioles , which receive air breathed in ...

8. Pulmonary circulation - Wikipedia

   en.wikipedia.org/wiki/Pulmonary_circulation

   De-oxygenated blood leaves the heart, goes to the lungs, and then enters back into the heart. [2] De-oxygenated blood leaves through the right ventricle through the pulmonary artery. [2] From the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve) into the right ventricle.
