Detailed explanation-1: -All the venous blood from the heart arrives at the coronary sinus which is located in the atrioventricular groove. The coronary sinus is the biggest cardiac vein, and it empties directly into the right atrium at the conjunction of the coronary and the interventricular grooves.
Detailed explanation-2: -Aortic regurgitation occurs when blood flows retrograde (backwards) across the aortic valve from the aorta into the left ventricle during diastole. This abnormal backflow of blood leads to pathologic changes in the heart-remodeling-in order to maintain effective forward cardiac output.
Detailed explanation-3: -The primary physiological function of the coronary veins is to carry deoxygenated blood from the myocardium and empty them into the chambers of the heart.
