Answer:
The correct option is: C. pump blood with greater pressure
Explanation:
The human heart is a muscular organ, present between the middle compartment of the chest and the lungs. Heart is responsible for pumping blood through blood vessels of the circulatory system. It is divided in the following four chambers: the right atria, left atria, right ventricle and left ventricle.
The wall of the left ventricle is thicker as compared to the wall of the right ventricle. This is because greater force is required to pump the blood to the entire body.
