What drains blood from myocardium?

Coronary veins are responsible for draining deoxygenated blood from the myocardium into the cardiac chambers. Comprised of two venous systems, coronary veins classify into either the greater cardiac venous system or the smaller cardiac venous system.

What vessels drain into right atrium?

The Heart and Blood Vessels Large blue vessel (vena cava) _(includes the superior and inferior vena cava) – _Large vein that empties blood into the right atrium of the heart.

Which blood vessel is responsible for drainage of blood from heart?

Hepatic vein, any of a group of veins that transports blood from the liver to the inferior vena cava, which carries the blood to the right atrium of the heart. In its ascent to the heart, the inferior vena cava passes along a groove in the posterior side of the liver, and it is there that the hepatic veins join it.

What are the only arteries that carry oxygen-poor blood in the body?

The inferior and superior vena cava bring oxygen-poor blood from the body into the right atrium. The pulmonary artery carries oxygen-poor blood from the right ventricle into the lungs, where oxygen enters the bloodstream. The pulmonary veins bring oxygen-rich blood to the left atrium.

What blood vessels drain blood into right atrium?

The coronary sinus drains into the right atrium, at the coronary sinus orifice, an opening between the inferior vena cava and the right atrioventricular orifice or tricuspid valve. It returns blood from the heart muscle, and is protected by a semicircular fold of the lining membrane of the auricle,…

What blood vessel brings blood into the right atrium?

The inferior and superior vena cava bring oxygen-poor blood from the body into the right atrium. The pulmonary artery carries oxygen-poor blood from the right ventricle into the lungs, where oxygen enters the bloodstream. The pulmonary veins bring oxygen-rich blood to the left atrium.

Does the pulmonary vein carry blood into the right atrium?

In partial anomalous pulmonary venous return, some of the pulmonary veins carrying blood from the lungs to the heart flow into other blood vessels or into the heart’s right atrium , instead of correctly entering the heart’s left atrium. This causes some oxygen-rich blood from the lungs to mix with oxygen-poor blood before entering the right atrium. In a normal heart, as shown on the left, oxygen-rich blood from the pulmonary veins returns to the left atrium.

Does the blood reenter the heart at the right atrium?

Oxygen-poor blood returns from the body to the heart through the superior vena cava (SVC) and inferior vena cava (IVC), the two main veins that bring blood back to the heart. The oxygen-poor blood enters the right atrium (RA), or the right upper chamber of the heart.
