Question

Coronary blood supply involves which arteries?

Option 1: Right coronary artery (RCA)
Option 2: Left anterior descending artery
Option 3: Left circumflex artery
Option 4: Left main coronary artery

Answer 1

The coronary blood supply involves the right coronary artery, left anterior descending artery, left circumflex artery, and left main coronary artery.

Step-by-step explanation:

The coronary blood supply involves several arteries that distribute blood to different parts of the heart. The arteries involved in coronary blood supply include:

1. Right coronary artery (RCA): This artery supplies the right side of the heart, including the right atrium, portions of both ventricles, and the heart conduction system.
2. Left anterior descending artery (LAD): This artery is a major branch of the left coronary artery and supplies blood to the left side of the heart, including the left atrium and ventricle, and the interventricular septum.
3. Left circumflex artery: This artery also arises from the left coronary artery and follows the coronary sulcus to the left, eventually fusing with the small branches of the right coronary artery.
4. Left main coronary artery: This is the main branch of the left coronary artery and gives rise to the LAD and circumflex artery.
