What is the difference between the atria and the ventricles of the heart?

The atria are the two upper chambers in the heart, and they receive blood entering from outside of the heart. The ventricles are the two lower chambers of the heart and they each receive blood from an atrium and then send it out of the heart.

What are the functions of the atria and the ventricles of the heart?
Atria is the receiving chamber and it is located at the top while ventricles are the one responsible for pumping blood out of the heart either to oxygenate the blood or to deliver it into our systems and it is located at the bottom part of the heart
What is the difference between an atrium and a ventricle in the mammal heart?
The atria are the two upper chambers and the ventricles are the two lower chambers.
Cardiac cycle when do you hear the first heart sound snd second?
when the ventricles closes and between the atria and the ventricles.
What part of the blood is atria and ventricles?
The Atria and Ventricles are parts of the heart not the blood. The Atria is the upper chambers of the heart and the Ventricles are the lower chambers of the heart.
Which chambers of the heart are the ventricles?
The ventricles are the lower chambers of the heart. The atria are the upper changes.
How would you say the structural difference reflects the relative functions of the two heart chambers?
Assuming you mean the atria and ventricles by "the two heart chambers", the fact that in all species the atria are smaller than the ventricles reflects the fact that the atria receive blood from either the body or the lungs and then pump it into the larger and much stronger ventricles. One-way valves between the atria and ventricles prevent backflow of blood from the ventricles to the atria. The ventricles then pump the blood received from the atria to either the oxygenating organ (i.e. gills or lungs) or the body. The much thicker walls of the ventricles reflect the fact that much greater force is needed to pump the blood throughout the body or to the lungs than is needed to pump the blood from the atria to the ventricles.
What do the AV valves in the heart do?
It means "atrioventricular". It refers to the valves between the atria and the ventricles.
Does the fibrous skeleton of the heart serves as electrical insulation between the atria and the ventricles?
Yesh.
How can you distinguish between an atrioventicular valve and a semivunar valve in the heart?
The atrioventricular valves are located between the atria and the ventricles. The semilunar valves are located between the ventricles and the arteries leaving the heart.
Are atria and ventricles organs?
No. They are in the organ of the heart
What major subdivision of the heart?
The atria and ventricles.
Are the atria are the lower chambers of the heart?
No. The lower chambers of the heart are called the ventricles. The atria are the top chambers of the heart.
