Best Answer

The heart is a complex structure. It receives deoxygenated blood from the superior and inferior vena cavas who transfer it to the right auricle. The right auricle due to excessive receival of impure blood, swells up and transfers it to the right ventricle. Although the left auricle and ventricle too perform contraction, the receival by the right side is enormous. It thus, contracts more forcefully compared to the left side.
