Summary Introduction

To determine:

The artery through which the middle cardiac vein runs.

Introduction:

Circulation of blood in the heart is not the source of heart nutrition because the wall of the heart is very thick and nutrition cannot diffuse in it by circulation of blood. The heart walls get nutrition with the help of coronary arteries that generally supply blood to the heart muscles. The veins carry deoxygenated blood while the arteries carry oxygenated blood.
