Detailed explanation-1: -The coronary sinus empties directly into the right atrium near the conjunction of the interventricular and coronary grooves (also known as the crux cordis area) [7], located on the inferior region of the right atrial septum between the inferior vena cava and tricuspid valve [8].
Detailed explanation-2: -The deoxygenated blood of the body returns to the right atrium of the heart via the superior vena cava and inferior vena cava. The coronary sinus delivers deoxygenated blood from the heart muscle directly into the right atrium.
Detailed explanation-3: -Coronary sinus drains the blood from most of the heart muscle and empties in the right atrium posteriorly, close to the opening of the tricuspid valve.
Detailed explanation-4: -Coronary veins are responsible for draining deoxygenated blood from the myocardium into the cardiac chambers.
