Summary Introduction

To discuss:

Why coronary artery blood flow is greater when the heart relaxes than when it contracts, in contrast to the arterialsystem almost everywhere else in the body

Introduction:

Coronary arteries supply oxygenated blood to the heart muscles. Like the other organs, the heart also needs oxygenated blood and nutrients for its functioning. These arteries supply blood to the anterior and posterior sides of the heart. Coronary blood flow is entirely reciprocal when compared to the other organ system blood flow, which is detailed here.
