Difficulty: EasyHuman Anatomy and Body Systems

Which vessel transports oxygen-poor blood directly from the heart into the lungs for reoxygenation?

  1. A
    Aorta
  2. B
    Pulmonary vein
  3. Pulmonary arteryAnswer
  4. D
    Inferior vena cava

Answer

Pulmonary artery
The pulmonary artery is the primary blood vessel responsible for transporting deoxygenated blood from the right ventricle of the heart directly to the pulmonary capillaries in the lungs for oxygen replenishment.

Step-by-Step Solution

1
Identify the direction of blood flow described in the problem
Blood is traveling away from the heart toward the lungs
Vessels carrying blood away from the heart chambers are classified as arteries.
2
Determine the oxygenation state and destination organ
The pulmonary artery moves oxygen-depleted blood from the right ventricle to pulmonary capillaries
In pulmonary circulation, the pulmonary artery is the primary vessel that carries deoxygenated blood to the lungs for gas exchange.
