Atria of the Heart: The atria of the heart are the upper two chambers of the heart. They include the left atrium and the right atrium and are a part of the cardiovascular system. The right atrium receives deoxygenated blood from the body via the superior vena cave and the inferior vena cava. Blood flows through the right atrium into the right ventricle, where it is pumped to the lungs. The left atrium receives freshly oxygenated blood from the lungs via the pulmonary veins. Blood flows through the left atrium into the left ventricle, where it is pumped to the other organs and areas of the body.
In a healthy person, the atria work with the ventricles of the heart to transport blood in a regular, strong rhythm that is activated by an electrical conduction system. The atria of the heart are supplied with blood by the coronary arteries.
Conditions that afflict the atria of the heart include myocardial infarction, infection, heart disease, cardiac arrhythmias, angina, trauma, birth defects, cardiac arrest, and atherosclerosis.
