The circulatory system is the correct answer because it is specifically designed to pump blood throughout the entire body. This system includes the heart, which acts as the pump, and a vast network of blood vessels (arteries, veins, and capillaries) that transport blood to and from different organs and tissues. The vital functions of the circulatory system include supplying oxygen and nutrients to cells, removing waste products, and playing a crucial role in temperature regulation and immune system functions.

The other options focus on different bodily functions: the nervous system controls and coordinates voluntary and involuntary actions, the respiratory system is responsible for the exchange of gases (oxygen and carbon dioxide) in the lungs, and the digestive system is involved in the breakdown and absorption of food. Each of these systems has its own distinct role, separate from the function of blood circulation, which is exclusively managed by the circulatory system.
