Difficulty: EasyHuman Anatomy and Body Systems

Blood exiting the right ventricle of the human heart must travel to the respiratory system to release carbon dioxide and absorb oxygen. Which blood vessel carries this deoxygenated blood directly to the lungs?

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

Answer

Pulmonary artery
The pulmonary artery is the anatomical vessel responsible for transporting deoxygenated blood from the right ventricle of the heart directly to the lungs for gas exchange. While most arteries carry oxygen-rich blood, the pulmonary artery is an exception because arteries are defined by carrying blood away from the heart regardless of oxygen saturation.

Step-by-Step Solution

1
Identify the origin and destination of the blood pathway
Blood is traveling from the right ventricle of the heart to the lungs.
The right side of the heart manages pulmonary circulation to oxygenate depleted blood.
2
Determine the specific vessel that carries blood away from the right ventricle to the lungs
The pulmonary artery is the vessel that transports blood from the right ventricle to the pulmonary capillaries.
All vessels leading away from the heart are classified anatomically as arteries, even when transporting deoxygenated blood.
