What are the Only Arteries That Carry Oxygen-Poor Blood in the Body

Question

What are the only arteries that carry oxygen-poor blood in the body?
A) circumflex artery
B) posterior interventricular artery
C) coronary arteries
D) pulmonary arteries

Accepted Answer

Pulmonary arteries are the only arteries in the body that carry oxygen-poor blood. They carry blood from the right ventricle of the heart to the lungs, where oxygen is added and carbon dioxide is removed. Once oxygenated, the blood returns to the heart through the pulmonary veins. The other answer choices (circumflex artery, posterior interventricular artery, and coronary arteries) are all part of the systemic circulation and carry oxygen-rich blood.
