In mammals what will blood returning from the head pass through just before entering the right atrium?
The veins from some parts of the body converge into two major pathways, the superior and inferior venae cavae, which lead to the right atrium.
Name the vessel that brings blood back to the right atrium?
both the superior and inferior vena cava pump the blood into the right atrium. Then, the right atrium pumps the blood through a valve, and into the right ventricle.
Function right atrium?
receives deoxygenated blood from the superior and inferior vena cava and transports it into the right ventricle
What artery supplies blood to the right atrium and right ventricle?
The right side of the heart receives blood from the right coronary artery and the posterior descending artery.
Where does the posterior inferior portion of the right atrium receive blood from?
superior vena cava
Where is the SA node in the heart?
The sino-atrial node (or SA node) is located in the right atrium, just below the entrance of the superior vena cava in the upper right portion of the right atrium.
What heart chamber dos the superior and posterior vana cava open on a fetal pig?
The heart chamber that the superior and posterior vena cava opens to on a fetal pig is the right atrium. The opening to both vena cava's are valveless.
Is the AV node or the SA node closest to the center of the heart?

In what chamber of the heart do the superior and inferior vena cava open?

Returns blood to the right atrium of the heart?
Either through the Superior Vena Cava located at the superior aspect of the heart, through the Coronary Sinus located at the inferior aspect of the heart, or through the Inferior Vena Cava located at the inferior aspect of the heart. All of these drain into the right atrium.
Which heart chamber receives blood from the superior vena cava?
right atrium
What chamber receives blood for the inferior and superior vena cava?
right atrium
The superior vena cava empties what?
