What are the two large veins that bring blood into the right atrium?
Superior and Inferior Vena Cava.
No, ventricles receive blood from the atria. The superior and inferior vena cava (large veins) both bring blood to the right atrium of the heart. Blood leaves the right atrium and enters the right ventricle. The right ventricle pumps blood to the lungs. The pulmonary veins return oxygenated blood from the lungs to the left atrium. Blood leaves the left atrium and enters the left ventricle. The left ventricle then pumps blood to the rest…
The blood in the right atrium comes from the large veins the superior vena cava and the inferior vena cava. It is impure blood or deoxygenated blood, and this is pumped down the right ventricle to the lungs for purification and oxygenation, and returned to the heart to be pumped out to supply the vital organs and tissues in the body.
You get deoxygenated or impure blood from the whole body. It enters the right atrium. Right atrium pumps the blood in right ventricle. From right ventricle blood goes to your lungs. Here the blood gets oxygenated or get purified. Then it enters your left atrium. Left atrium pumps the blood in left ventricle. Left ventricle pumps the blood to your whole body.
