Detailed explanation-1: -The coronary venous network drains deoxygenated blood from the myocardium into one of two systems: the greater cardiac venous system and the smaller cardiac venous system. These systems are comprised of many complementary veins, the majority of which coalesce to form the coronary sinus.
Detailed explanation-2: -Answer and Explanation: All cardiac veins empty into the coronary sinus, which then empties into the right atrium.
Detailed explanation-3: -What is the vena cava? The superior vena cava and inferior vena cava are very large veins that bring deoxygenated blood to your heart to get oxygen.
Detailed explanation-4: -The middle cardiac vein, also known as the posterior interventricular vein, is a vessel located on the posterior aspect of the heart. It arises at the cardiac apex and runs within the posterior interventricular groove. It ends by draining into the right atrium via the coronary sinus.
