The left atrium collects oxygen-rich blood from the lungs, and upon contraction, transfers it to the left ventricle. The left ventricle then pumps the oxygenated blood to the rest of the body.
What is the role of the left atrium and left ventricle in the oxygen-rich blood circulation process?

The left atrium and ventricle play a crucial tandem role in your oxygen-rich blood highway. Think of the atrium as a receiving station, welcoming oxygen-rich blood from the lungs through the pulmonary veins. It then gently passes it onward to the powerful left ventricle, the pumping station. This muscular chamber contracts forcefully, sending the oxygen-rich blood through the aortic valve and out to fuel your entire body. The left atrium and ventricle work together, ensuring a steady flow of vital oxygen to keep you going!
