Coronary artery

In medicine, the coronary arteries are the arteries that supply blood to the heart.

Left main coronary
 * Left anterior descending (LAD)
 * Branches are called the septals and diagonals
 * Ramus intermedius arises from the left main between the LAD and the circumflex in some people.
 * Circumflex
 * Branches are called the obtuse marginals
 * In a minority of people, the circumflex provides the posterior descending artery.

Right coronary
 * In most people, the right coronary provides the posterior descending artery.
