Body receives blood through arteries. Which one is out of place?

biology transport in mammals cardiac cycle heart, blood vessels and cardiac cycle human heart

  1. Aorta

  2. Renal artery

  3. Coronary artery

  4. Pulmonary artery

Show answer
Correct Option: D
Explanation:
A. Aorta is the largest artery in body which supplies blood from heart to rest of the body parts.
B. Renal arteries are blood vessels that branch from abdominal aorta and supply blood to the kidneys.
C. Coronary arteries supply the oxygenated blood to heart.
D. Pulmonary artery carries deoxygenated blood from right ventricle to the lungs. 
Hence, body receives blood through arteries except the lungs which receive deoxygenated blood through pulmonary artery.
So, the correct answer is 'Pulmonary artery'.
