The atria
The right side of the heart receives oxygen-poor blood from the body and pumps it to your lungs. The left side receives oxygen-rich blood and from the lungs and pumps it into the body.
The left side of the heart receives blood from the lungs which is rich in oxygen. The heart then pumps throughout the body.
Blood
The left atrium receives blood from the lungs. This blood moves into the left ventricle to be sent out to the body.
Oxygen poor blood is returned to the heart, which pumps it to the lungs where it gets oxygenated, and then it goes back to the heart, and then back out to the body.
The heart receives blood from the lungs on the left side through the Pulmonary Veins.
The left side of the heart receives the oxygen-rich blood from the lungs and pumps it to the body.
It's the side that receives blood from your body and sends blood to the lungs to pick up oxygen.
maybe your question goes this way..."how does oxygen enter the blood from the lungs?"Two types of blood vessels carry blood throughout our bodies: The arteries carry oxygenated blood (blood that has received oxygen from the lungs) from the heart to the rest of the body. The blood then travels through the veins back to the heart and lungs, where it receives more oxygen.
When your heart receives oxygen-rich blood from your lungs, it pumps it out through your arteries. They carry blood away with a good deal of pressure.
The left atrium of the heart receives oxygented blood from the pulmonary veins returning oxygenated blood to the heart.
The left atrium receives blood returning to the heart from the lungs.
