It is caused by pressure exerted on the chest wall at the outset of systole by the rounded and hardened ventricular wall. During atrial systole, blood not only empties from the atria to the ventricles, but continues to flow uninterrupted from the veins right through the atria into the ventricles. The two atria are thin-walled chambers that receive blood from the veins. 17.1D: Chambers of the Heart is shared under a CC BY-SA license and was authored, remixed, and/or curated by LibreTexts.

The right atrium receives deoxygenated blood from systemic circulation and the left atrium receives oxygenated blood from pulmonary circulation. The four heart chambers and four valves work together to separate the oxygen-rich blood from the oxygen-poor blood. Teamwork, again, is key. The blood in the pulmonary artery branches is low in oxygen but relatively high in carbon dioxide. The right atrium receives deoxygenated blood from systemic circulation through the superior vena cava and inferior venae cavae. Table of Contents Introduction Position Functions of the Human Heart Types of Circulation Best Answer. The lower chambers, the more muscular right and left ventricles, pump blood out of the heart.
