Which heart chamber receives blood from the left atrium?

The left ventricle is the chamber of the heart that receives oxygen-rich blood from the left atrium. This process is essential for proper blood circulation throughout the body.

After oxygenated blood is collected in the left atrium from the pulmonary veins, it flows through the mitral valve into the left ventricle. The left ventricle then contracts, pumping this oxygenated blood into the aorta, which distributes it to the rest of the body. This functionality highlights the critical role of the left ventricle in maintaining efficient blood flow and supplying tissues with the oxygen they need for metabolic processes.

The other options do not appropriately describe the chamber that receives blood from the left atrium. The right ventricle receives deoxygenated blood from the right atrium, the right atrium receives blood from the body (deoxygenated), and the aorta is the large blood vessel that distributes oxygenated blood away from the heart, not a chamber that receives blood directly from the atrium.
