Cornary sinus
This statement is incorrect. Oxygenated blood is found in the left atrium of the heart, having been pumped from the lungs by the left ventricle. The right atrium receives deoxygenated blood from the body.
The blood pressure within the right atrium is called central venous pressure (CVP). It is a measure of the pressure in the large veins close to the heart and reflects the amount of blood returning to the heart.
The up right chamber of heart known as the right atrium receives the deoxygenated blood from all over the body. This blood is then passes to the right ventricle through a tricuspid valve which is then sent to the lungs for oxygenation.
Absorption at the arachnoid granulations returns cerebrospinal fluid (CSF) to the bloodstream by allowing CSF to enter the venous circulation. This process helps maintain the balance of CSF in the brain and spinal cord.
There is no system that actually does that, the closest thing to that process is the heart and veins that returns lymphatic fluid, which is basically interstitial fluid plus white blood cells. The Lymphatic system.
Coronary sinus
Coronary Sinus
The structure you are referring to is likely the coronary sinus. It is a collection of veins that drain deoxygenated blood from the heart muscle itself back into the right atrium of the heart. It serves as the main venous drainage for the heart.
i dont know im cedrick
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.
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.

The venous or deoxygenated blood flows into the right atrium. Then is goes to the right ventricle. From there it is pumped out to the lungs to get oxygenated and back into the left atrium then to the left ventricle and from there to the rest of the body.
