The heart is comprised of two atria and two ventricles. It pumps this blood through the right atrioventricular orifice (guarded by the tricuspid valve) into the right ventricle.
Atria) is one of the four chambers of the human heart, and is the first chamber to receive deoxygenated blood returning from the body, via the two venae cavae. The right atrium, like its left counterpart, can be divided into four anatomical regions, the septal component, the right atrial appendage, the venous component, the vestibule of the tricuspid valve.

The main utility of this projection is. The coronary sinus is located on the heart’s posterior (behind) surface and is positioned between the left ventricle and the left atrium. The right atrium forms the entire right border of the human heart.
It Gives A Slightly Oblique Four Chamber View That Provides Information About The Right Ventricular Inlet.
The raa is very muscular, and is lined with small muscles on its surface. The right atrium forms the right border of the heart. Deoxygenated blood entering the heart through veins from the tissues of the body first enters the heart through the right atrium before being pumped into the right ventricle.
Internally, This Corresponds To The Crista Terminalis.
It pumps this blood through the right atrioventricular orifice (guarded by the tricuspid valve) into the right ventricle. The right atrium is one of the four hollow chambers of the interior of the heart. Posteriorly, it supports the coronary sinus, positioned in the atrioventricular.
