In human cardiovascular circulation, blood vessels are functionally classified by the direction in which they transport blood relative to the heart. Which blood vessel carries deoxygenated blood away from the right ventricle toward the lungs?

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

Cevap

The pulmonary artery carries deoxygenated blood away from the right ventricle to the lungs.
Arteries are defined as vessels that carry blood away from the heart. While systemic arteries carry oxygenated blood, the pulmonary artery carries deoxygenated blood away from the right ventricle directly into the lungs for reoxygenation and carbon dioxide elimination.

Adım Adım Çözüm

1
Identify the anatomical definition of arteries versus veins in the cardiovascular system.
Arteries always transport blood away from the heart ventricles, while veins transport blood toward the heart atria.
Blood vessel classification is fundamentally based on flow direction relative to the heart, not solely on oxygen saturation levels.
2
Trace the pathway of deoxygenated blood leaving the right side of the heart.
The right ventricle pumps deoxygenated blood into the pulmonary trunk and pulmonary arteries to reach the pulmonary capillaries in the lungs.
In the pulmonary circuit, the pulmonary artery is the specific vessel carrying deoxygenated blood away from the heart for gas exchange.
