Blood vessel carrying blood from lung to heart through_______.

The pulmonary artery carries deoxygenated blood from the right ventricle to the lungs.

The pulmonary vein carries oxygen-rich blood from the lungs to the left auricle. The blood picks up oxygen in the lungs, and the pulmonary veins return it to the heart, where it is then pumped to the rest of the body. This continuous loop ensures that the body's tissues receive the oxygen and nutrients they need to function properly.

The coronary artery delivers oxygenated blood to the cardiac muscles.

The coronary veins are blood vessels that drain blood from the heart muscle. They return deoxygenated blood from the heart to the right atrium, which then pumps it to the lungs for oxygenation. The coronary veins play an important role in the circulatory system by helping to regulate blood flow to the heart.
