vena cava
Superior Vena Cava
The two upper chambers are called the atria. A single atria is an atrium.
The major vein that leads into the right atrium is the vena cava. The superior vena cava carries deoxygenated blood from the upper part of the body into the right atrium. The inferior vena cava carries deoxygenated blood from the lower part of the body into the right atrium.
the upper chambers of the heart are called the atria. (or atrium singular)
The right atrium and left atrium (plural atria) are the upper chambers of the heart. They are superior to the right and left ventricles, respectively.
The right atrium is the upper chamber of the right side of the heart. It is located superior to the left ventricle.
The superior vena cava supplies the deoxygenated blood from the upper half of the body into the right atrium
Right atrium: The right upper chamber of the heart. The right atrium receives deoxygenated blood from the body through the vena cava and pumps it into the right ventricle which then sends it to the lungs to be oxygenated.
The interatrial septum separates the left atrium from the right atrium (the atria are the upper chambers of the heart).
The left and right atrium (or atria).
The upper chamber on the right side of the heart.
The upper right chamber of the heart is known as the right atrium. It is located in the upper portion of the heart, receiving deoxygenated blood from the body through the superior and inferior vena cavae. The right atrium then pumps this blood into the right ventricle, which sends it to the lungs for oxygenation.
