Correct answer: B. Coronary artery
- A. Pulmonary artery
- B. Coronary artery
- C. Hepatic artery
- D. Iliac arteries
Explanation
Option B is correct.The first artery that arises from the base of the aorta is the coronary artery. There are two main coronary arteries: the right coronary artery and the left main coronary artery (LMCA). The LMCA bifurcates into the left anterior descending artery (LAD) and the left circumflex artery (LCx). The LAD supplies blood to the front and bottom of the heart, while the LCx supplies blood to the back and sides of the heart. The coronary arteries are responsible for supplying blood to the heart muscle. The heart muscle needs a constant supply of oxygen-rich blood in order to function properly. If a coronary artery becomes blocked, it can lead to a heart attack.
