Chest wall blood sup: The ima [internal mammary artery] supplies blood to the anterior chest wall. It's branches supply the chest wall and muscles as well as the breasts. It is paired with one on each side of the sternum. It is rarely affected by atherosclerisis making it a perfect blood supply for the coronary vessels during cardiac bypass surgery. It connects to the upper blood supply of the abdomen.

Blood to chest wall: The internal mammary artery which supplies blood to the chest wall is often used in coronary artery bypass grafting as it has proven to be more durable than veins which are often taken from the legs.
