The ventricles have to be firmer and more muscular because they have to pump blood much further than the atria.

Why do heartbeats occur?
Heart has to beat periodically. Atrial chambers of your heart receive blood from your body and lungs. This is pushed to your ventricles by contraction of the atrial chambers, leading to formation of beats. The ventricles also have to pump blood to your lungs and body by contraction of the ventricles. You need time to fill the ventricles and you need to contract the ventricles. This leads to formation of heart beats. Continuous flow, with out beats is not possible here. Although the blood flows continuously. Because, when the ventricles relax, the arterial system, contracts.
