There are no vessels that drain the right atrium, except, perhaps the coronary veins. The right atrium moves blood through the tricuspid valve into the right ventricle of the heart.

What Right pulmonary veins does it do?
The right pulmonary vein brings oxygenated blood from the lungs to the left atrium of the heart.
Can blood go backwards from the right ventricle to the right atrium?
That is partly true, but thinking of atrial function only in this way is misleading. The right atrium has a job that is subtle and very important. The atria do not have valves at the 'intake' end, so there is not a push in the same way that ventricles push blood. When the right atrium is in systole, or contracting, the contraction is not strong; if it were it would cause back flow to the veins feeding the right heart. While the atrium contracts, the relaxing right ventricle is taking in blood from the atrium. But at the same time, blood is still flowing directly from the veins right into the right ventricle! Then when the ventricle is contracting and sending blood to the lungs, blood flow can continue unimpeded into the relaxing atrium. So the atrium's job is really to prevent inertia of blood during the beating cycle; it helps the blood to keep moving without coming to a jolting stop during each beat.
What structures empty into left atrium?
the pulmonary veins, the only veins to carry oxygenated blood empty into the left atrium.
Where does the blood flows to after the cappilaries?
From the capillaries blood flows to the venules to the veins to the vena cava to the heart (right atrium).
Do placentals have a four chambered heart?
All mammals (monotremes, marsupials, and placental mammals) have the same heart structure: a four chambered heart. The four chambers are the left atrium, the left ventricle, the right atrium, and the right ventricle. The right atrium receives deoxygenated blood from the veins. It pumps it into the right ventricle. The right ventricle pumps it into the pulmonary arteries, which go to the lungs. The lungs have received oxygen and give it to the blood coming through. The now oxygenated blood flows back to the heart by pulmonary veins, and is received by the left atrium. The left atrium pumps the oxygenated blood into the left ventricle. The left ventricle pumps the blood to all of the body through arteries.
What is the name of the structure receiving the coronary veins?
The coronary veins drain into the coronary sinus, which in turn drains into the right atrium.
Where is the mitral vein found?
The Mitral Vein is one of those osbcure little veins that you do not often hear about. The Heart itself requires a blood supply, which comes from the Coronary Arteries and a system called the Cardiac supply. The blood is, as usual, supplied by arteries and must be removed in veins. These veins drain (mostly) into the Coronary Sinus which drains directly into the Right Atrium (the veins that bypass the sinus also drain directly into the right atrium). The mitral vein drains the supply from the region around the Mitral Valve (the valve between the Left Atrium and the Levt Veintricle) and it in turn drains directly into the coronary sinus. In the left side of the heart, near the Mitral, or bicuspid, valve.
Which veins are directly connected to the right atrium?
pulmonary vein
Which veins directly connected to the right atrium?
pulmonary vein
Drians unoxygenated blood from the myocardium?
The coronary veins drains the unoxygenated blood and empty it into the coronary sinus, which empties into the right atrium.
Where does Lymph drains directly into blood at?
lymph is collected by the thoracic duct and right lymphatic duct and is directly drained into the blood at the right and left subclavian veins
How many veins does a human leg have?
Is'intthere two? the left gonadal vein drains into the leftrenal vein, and the right drains directly into theinferior vena cava.-sourceWikipedia.
The superior vena cava carries what?
The superior vena cava receives blood from the right and left brachiocephalic veins, which in turn receive blood from the right and left subclavian veins (upper limbs), and right and left internal jugular veins (head). It drains into the right atrium of the heart.
What part of the heart receives oxygen blood from the lungs?
The right atrium which passes it to the right ventricle
Vein that drains the ovaries or testes?
In either case there is a bed of veins called the pampiniform plexus which directly drain the organs blood supply. The plexus then drains into discreet veins; from the ovaries, the ovarian veins and from the testes, the testicular veins. These discreet veins connect directly to the inferior vena cava.
What type of blood vessel always leaves an atrium?
Veins, specifically the vena cava, enters the right atrium of the heart.
How many pulmonary veins empty into the right atrium?
none. there are 4 pulmonary veins and they all empty into the left atrium, except in cases of congenital heart disease with anomalous pulmonary venous return to the right atrium.
