Problems with the right atrium can occur from birth or due to problems with the heart valves or muscles.
17 sie 2023 · The right atrium and ventricle make up most of the sternocostal surface of the heart, while the diaphragmatic surface is made up by the right and left ventricles. The left atrium contributes to the anatomical base.
The right atrium (RA) is situated in the superior right corner of the heart above the right ventricle (RV). The systemic circulation ends in the right atrium, as deoxygenated blood from the tissues of the body enters it through the superior and inferior vena cava, and the coronary sinus (collects venous blood from the heart itself).
The right atrium sits anterior, inferior and to the right of the left atrium. It forms a portion of the upper anterior (sternocostal) surface and a portion of the right pulmonary surface of the heart. The right atrium has thin muscular walls as it functions under low pressure.
Right atrium. The right atrium receives and holds deoxygenated blood from the superior vena cava, inferior vena cava, anterior cardiac veins, smallest cardiac veins and the coronary sinus, which it then sends down to the right ventricle through the tricuspid valve, which in turn sends it to the pulmonary artery for pulmonary circulation.
The right atrium is responsible for receiving deoxygenated blood from the body through the vena cava and pumping it into the right ventricle, to be sent to the lungs, where it becomes oxygenated.
