Explanation The left ventricle receives blood through two branches of the left coronary artery (LCA). This artery originates from the left region of the aorta and then gives rise to two branches called anterior interventricular artery and circumflex arteries. The anterior interventricular artery is also known as left anterior descending artery and it supplies blood into the interventricular septum and the anterior walls of the ventricles...

Chapter 19, Problem 12CYU

Summary Introduction

To review:

The vessel that supplies blood to the left ventricle.

Introduction:

The structure of the heart consists of four chambers out of which two are auricles or atria and the other two are ventricles. The ventricles collect and expel blood which they receive from the atria of the heart. The atrium which is the upper heart chamber is smaller than the ventricles. The ventricles of the heart function in pumping blood to the lungs and the entire body.
