Cabg is a procedure used to improve the flow of bellod through what?

The correct answer is coronary arteries.

Coronary artery bypass grafting (CABG) is a surgical procedure that improves blood flow to the heart. It is used to treat coronary artery disease, which occurs when the arteries that supply blood to the heart become narrowed or blocked.

During CABG, the surgeon takes a healthy blood vessel from another part of the body, such as the leg or arm, and grafts it to the coronary artery that is blocked. This creates a new pathway for blood to flow to the heart.

CABG is a major surgery, but it is often successful in improving symptoms and preventing heart attacks.
