   Capillaries join the arteries and veins. The circulatory system is a system of organs that includes the heart, blood vessels, and blood which is circulated throughout the entire body of a human or other vertebrate.

   The left anterior descending artery (also LAD, anterior interventricular branch of left coronary artery, or anterior descending branch) is a branch of the left coronary artery. It supplies the anterior portion of the left ventricle. [1] It provides about half of the arterial supply to the left ventricle and is thus considered the most important ...
