Correct:
A
Explanation
In the human circulatory system, veins generally carry deoxygenated blood from the body's tissues back toward the heart. The Pulmonary vein is a unique exception to this rule; it carries oxygen-rich (oxygenated) blood from the lungs to the left atrium of the heart.
- Cystic vein: Drains deoxygenated blood from the gallbladder.
- Cardiac vein: Returns deoxygenated blood from the heart muscle (myocardium) to the right atrium via the coronary sinus.
- Hepatic Portal vein: Transports deoxygenated but nutrient-rich blood from the gastrointestinal tract and spleen to the liver.
Similarly, the pulmonary artery is the only artery that carries deoxygenated blood (from the heart to the lungs). While the umbilical vein also carries oxygenated blood in fetal circulation, the pulmonary vein is the standard answer in general human anatomy.
