One of a pair of small chambers of the heart that receive blood from the veins and expel it into the ventricles, the pumping chambers of the heart.<\/p>\n

\n

One of the upper chambers of the heart. The right atrium receives venous blood from the systems of the body while the left atrium receives oxygenated blood from the lungs.<\/p>\n

\n

One of the two upper chambers in the heart.<\/p>\n

\n

A cavity in the ear behind the eardrum.<\/p>\n

\n

Either of the two upper chambers of the heart. The right atrium receives deoxygenated blood from the vena cava and then passes it into the right ventricle, which pumps it to the lungs, where it gives off waste products and receives oxygen. The freshly oxygenated blood then passes through the pulmonary vein to the left atrium and from there to the left ventricle and then the rest of the body.<\/p>\n

\n

Two upper heart chambers directly above the ventricles, called right and left atrium, respectively.<\/p>\n

\n

Either of the two upper chambers of the heart. The right atrium receives oxygen-depleted blood from the body and moves it into the right ventricle, where the blood is pumped into the lungs to dispose of waste products (carbon dioxide) and receive oxygen. The oxygen-rich blood then returns to the left atrium, passes into the left ventricle, and is pumped through the aorta into the rest of the body. The tricuspid valve divides the right atrium from the right ventricle, letting blood flow from the one into the other and preventing backwash. The mitral valve performs the same function between the left atrium and the left ventricle.<\/p>\n

\n

Either of the two upper chambers of the heart. Their muscular walls are thinner than those of the ventricles; the left atrium receives oxygenated blood from the lungs via the pulmonary vein; the right atrium receives venous blood from the venae cavae.<\/p>\n

\n

The two upper cavities of the heart. These used to be known as the auricles. The term is also applied to that part of the ear immediately internal to the drum.<\/p>\n

\n

A chamber or cavity communicating with another chamber or passageway.<\/p>\n

\n

A chamber of the heart that receives blood that is returning to the heart.<\/p>\n

\n

Thin-walled, upper chamber of the heart through which blood is pumped to the ventricles. There is a right atrium and a left atrium.<\/p>\n

\n

The atria, also known as auricles, refer to the two upper chambers of the heart, namely the right atrium and the left atrium. These chambers directly connect to the ventricles, which are the lower chambers of the heart. The right atrium receives deoxygenated blood from the body through the venae cavae, while the left atrium receives oxygenated blood from the lungs via the pulmonary veins. The atria play a vital role in facilitating the flow of blood through the heart, ensuring effective oxygenation and circulation.<\/p>\n

\n

One of the heart’s two upper chambers that receives blood and pumps it into the corresponding lower chamber, or ventricle. The right atrium takes in deoxygenated blood from the body, sending it to the right ventricle and onward to the lungs for oxygenation. Oxygen-rich blood from the lungs moves into the left atrium, which pumps it into the left ventricle. The left ventricle then propels the blood into the aorta. The term “atrium” is also used to describe a part of the middle ear cavity situated below the head of the malleus, as well as the front area of the nasal cavity.<\/p>\n
