   Sep 2, 2021 · Function of Heart Atria. The atria of the heart receive blood returning to the heart from other areas of the body. Right Atrium: Receives blood returning to the heart from the superior and inferior venae cavae. The superior vena cava returns de-oxygenated blood from the head, neck, arm and chest regions of the body to the right atrium.

8. People also ask

   Which atria receives blood into the heart?

   • The two atria receive blood into the heart and the two ventricles pump blood into circulation. The right and left atria are the top chambers of the heart and receive blood into the heart. The right atrium receives deoxygenated blood from systemic circulation and the left atrium receives oxygenated blood from pulmonary circulation.

   How does the left ventricle pump blood through the aorta?

   • The left ventricle receives oxygenated blood from the left atria and pumps it through the aorta into systemic circulation to supply the tissues of the body with oxygen. The walls of the ventricles are thicker and stronger than those of the atria.

   What is the function of the atria & ventricles?

   • Each of the upper chambers, the right atrium (plural = atria) and the left atrium, acts as a receiving chamber and contracts to push blood into the lower chambers, the right ventricle and the left ventricle. The ventricles serve as the primary pumping chambers of the heart, propelling blood to the lungs or to the rest of the body.

   The heart is the complex pump of the circulatory system, pumping blood throughout the body for the purposes of tissue oxygenation and gas exchange. The heart has four chambers through which blood flows: two sets of each type of chamber (atria and ventricles), one per side, each with distinct functions. The left side of the heart deals with ...
