Option 2: Pulmonary artery
Option 3: Pulmonary vein
Option 4: Renal artery
Correct Answer: Pulmonary vein
Solution : The correct option is - Pulmonary vein
The blood vessels that carry oxygenated blood from the lungs to the heart are called pulmonary veins. There are typically four pulmonary veins in the human body, two from the right lung and two from the left lung, and they all converge to transport oxygen-rich blood back to the left atrium of the heart. From the left atrium, the oxygenated blood is pumped into the left ventricle and then sent out to the rest of the body through the aorta when the heart contracts. This circulation is part of the systemic circulation system, which delivers oxygen and nutrients to the body's tissues and organs.
