chamber of the heart that receives oxygenated blood from the lungs and delivers it to the left ventricle in preparation for systemic circulation
Receives oxygen-rich blood from the lungs and passes it to the left ventricle.
The upper right chamber of the heart. The left atrium receives oxygenated blood from the lungs and pumps it down into the left ventricle which delivers it to the body.
The upper left-hand chamber of the heart. It receives oxygen-rich (red) blood from the lungs, and then sends this blood to the left ventricle.
The upper (or "priming") pumping chamber on the left side of the heart. The left atrium sits above the mitral valve and gently forces blood across the mitral valve into the left ventricle. This actions "primes" the lower pumping chamber to improve efficiency. At the same time, the left atrium provides a temporary storage site for blood returning from the lungs during the time that the left ventricle is actually squeezing.
One of the four chambers of the heart which oxygen-rich blood enters after leaving the lungs. Reference: H1
The left upper chamber of the heart that receives oxygenated blood from the lungs via the pulmonary veins.
the left upper chamber of the heart. It receives oxygen-rich blood from the lungs via the pulmonary vein.
Blood from the lungs that is high in oxygen flows through the pulmonary veins and into the left atrium.
The heart has four chambers. The right atrium is best developed and receives the sinus venosus. A partial septum separates right and left atria.
The left atrium is one of the four chambers in the human heart. It receives oxygenated blood from the four pulmonary veins, and pumps it into the left ventricle.
