Contraction of veins would increase venous return to the right atrium. It would increase the efficiency of the heart pumping.
From the venous system, blood enters the right atrium, then goes to the right ventricle, then in to the pulmonary system, then to left atrium, then left ventricle then back out to the body.
The coronary system is comprised of arteries, arterioles, capillaries, venules and veins. From the innumerable cardiac capillaries, blood flows back to the cardiac chambers through venules, which in turn coalesce into the cardiac veins. Most cardiac veins collect and return blood to the right atrium through the coronary sinus; there may or not be a Thebesian valve covering the ostium of the coronary sinus. The major venous vessels of the human heart are: coronary sinus, the anterior interventricular veins, left marginal veins, posterior veins of the left ventricle, and the posterior interventricular veins (see also the Coronary System Tutorial).
the blood starts at the right ventricle then goes to the semi lunar valve to the lungs via the pulmonary artery then from the lungs back to the left atrium via the pulmonary vein then through the bicuspid/ av valve to the left ventricle to the semi lunar valve through the aorta back to the body through the vena cave then to the right atrium through the tricuspid valve back to the right ventricle
The code you are looking for is 33511.
No. Right atrium is collecting venous (low oxygen) blood from all over the body.
The great cardiac vein is one of the largest veins in the body. It is located in the heart, leading away from the coronary sinus. It's function is to lead blood that has had the oxygen removed from it away from the heart.

Blood flows from the venous system to the right atrium of the heart to the right ventricle of the heart through the pulmonary arteries, to the lungs (where the CO2/O2 exchange is done) through the pulmonary veins, and back to the left atrium of the heart, to the left ventricle of the heart, and out through the aorta and to the rest of the body. It then returns through the veins and repeats the process.
