Question:

The primary function of which biological system is to move nutrients and chemicals through the body?

A Circulatory
Explaination

The circulatory system gets its name from the fact that it circulates blood and other substances throughout the body in the bloodstream. These chemicals include nutrients obtained from food, as well as oxygen, carbon dioxide and other chemicals and hormones. The digestive system breaks down food into proteins, fats and sugars that the body can use. The respiratory system exchanges oxygen and carbon dioxide between the air and the body tissues. The urinary system removes wastes from the body.
