yes, the hearts atria is bigger because its leads out the body from the lungs.
The atria and the ventricles
The Ventricles are bigger and rougher than the AtriumsThe Ventricles are bigger and rougher than the Atriums.sizeshapewall thickness
ventricles are the pumping chambers of the heart, so they have to be thicker and bigger to exert enough force to perform their function.
When relaxed, the atria expand, and then the ventricles contract.
Yes, atria contracts before the ventricles.
the difference between the ventricles and the atria is that the ventricles are thicker
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.
The human heart has four chambers.The upper two chambers are called Atria and the lower two are called Ventricles
A three chambered heart has two atria and one ventricle. Only amphibians and reptiles have three chambered hearts.
to force blood to the ventricles
There are no valves between the atria. The valves between the atria and ventricles close when the ventricles contract.
