Function of the Atria
The atria of the heart receive blood returning to the heart from other areas of the body.
Right Atrium: Receives blood returning to the heart from the superior and inferior venae cavae. The superior vena cava returns de-oxygenated blood from the head, neck, arm and chest regions of the body to the right atrium. The inferior vena cava returns de-oxygenated blood from the lower body regions (legs, back, abdomen and pelvis) to the right atrium.
Left Atrium: Receives blood returning to the heart from the pulmonary veins. The pulmonary veins extend from the left atrium to the lungs and bring oxygen-rich blood back to the heart.

∙ 7y agoThe atria act as a supercharger for the ventricles (pushes a little bit more blood into them). The ventricles are the actual blood pumps ( that push blood around the body ( or the lungs).

What is the plural form of atria?
Atria is the plural for of atrium. Not the other way around.
Structure that carries the heart electrical impulse into the ventricle?
The atrioventricular (AV) node sends the signal to the AV bundle, where the wave of contraction travels from the atria to the ventricles.
What do the atria do at the same time?
Both atria open and close simultaneously.
What are the atria?
They are the two upper chambers of the heart
What valve is between the R atria and the R ventricle?
there is a tricuspid valve in between the right atria and ventricle.
Function of atria?
ventricles
What is the main function of the right atria left atria?
to force blood to the ventricles
What is the function of the Atria in a vertebrates heart?

What is the function of the atria in the vertebrate heart?
The atria are chambers that receive blood that returns to the heart.
What are the ear-like structure that extend from the atria?
The ear-like structures that extend from the atria are the Auricles.
What chambers of the heart function to receive blood from veins?
Atria receive blood from the veins.
What structure completely separates the atria from the ventricles?
septum
What chamber of the heart function receive blood from the vein?
atria
What is the function of the chords attached to the valve flaps between the atria and the ventricle?
These chords are called the Chordea Tendinae. Their function is to stop the valves from invertung back into the atria. If they weeken and stretch they start to allow the valves to be pushed back into the atria, this is called floppy valve syndrome.
In longitudinal section how do the walls of the atria and ventricles differ?
In longitudinal section, the walls of the atria are thinner, and lined with pestinate muscles. The walls of the ventricles, meanwhile, are thick and muscular.
Is the function of the atria?
Its main function is to receive the blood that will then be pumped throughout the ventricles as well as the rest of the body.
What is the function of left?
The function of the left atria is to collect oxygenated blood from the pulmonary arteries and push it into the left ventricle.
