Detailed explanation-1: -Generally, atria are the smaller upper chambers while ventricles are the larger lower chambers of the heart. The main difference between atria and ventricles is that atria receive blood into the heart whereas ventricles pump blood outside the heart.
Detailed explanation-2: -The ventricles are the bottom two chambers of the heart, one on the left and one on the right side. They are larger, thicker and contain more myocardium than the atria.
Detailed explanation-3: -Ventricles have thicker walls than atria because they have to do more work. Both atria act as receiving chambers for incoming blood and then pump the blood directly into the ventricles.
Detailed explanation-4: -The right part of our heart has an atrium and one ventricle, while the case is the same for the left side too. The walls of the ventricles are thicker, while that of the atria are thinner.
