Which of the Following is Not Considered a "Great" Vessel

Question

Which of the following is not considered a "great" vessel?
A) Left anterior descending artery
B) Aorta
C) Venae cavae
D) Pulmonary artery

Accepted Answer

The left anterior descending artery is not considered a "great" vessel as it is a small branch of the coronary artery system that supplies blood to the heart muscle. The other vessels listed are all major blood vessels that play significant roles in circulation. The aorta is the largest artery in the body and carries oxygenated blood from the heart to the rest of the body. The venae cavae are the two largest veins in the body that return deoxygenated blood from the body to the heart. The pulmonary artery carries deoxygenated blood from the heart to the lungs where it is oxygenated.
