Explanation:
Detailed explanation-1: -After the blood gets oxygen in the lungs, it is called oxygen-rich blood. Oxygen-rich blood flows from the lungs back into the left atrium (LA), or the left upper chamber of the heart, through four pulmonary veins.
Detailed explanation-2: -The blood vessel that normally carries oxygen rich blood is known as veins.
Detailed explanation-3: -The right side of the heart pumps oxygen-poor blood from the body to the lungs, where it receives oxygen. The left side of the heart pumps oxygen-rich blood from the lungs to the body. Once the body’s organs and tissues have removed the oxygen from the blood, the blood returns to the heart.
