Explanation The coronary sinus is the major vein of the heart, which is formed when different veins join together. It is found on the posterior aspect of heart inside the coronary sulcus. It opens into the heart's right atrium across the orifice of tricuspid valve and IVC. Its main tributaries are a middle cardiac vein, small cardiac vein, as well as a great cardiac vein. Great cardiac vein: It starts from the apex of heart as well as extends to the base of ventricle along with anterior interventricular sulcus...

Chapter 21, Problem 30CP

Summary Introduction

To review:

The three tributaries of the coronary sinus.

Introduction:

In the systemic circulatory system, the superior vena cava, as well as inferior vena cava (IVC), transports deoxygenated blood to the heart's right atrium. After filling the right atrium, the tricuspid valve opens as well as allows blood to enter into the right ventricle, from which blood is transferred to the lung to convert it into the oxygenated blood. Coronary sinus also transfers deoxygenated blood to the right auricle from the myocardium (heart muscle).
