उत्तर
- Pulmonary vein carries the maximum content of oxygen.
- Pulmonary circulation moves deoxygenated blood from the heart to the lungs for oxygenation and it returns to the heart as oxygenated blood. Systemic circulation pushes the oxygenated blood from the heart towards various body parts (except lungs) and returns back to the heart as deoxygenated blood.
- Pulmonary vein is the only blood vessel that carries freshly oxygenated blood from the lungs to the heart for distribution to the body.
