Begin by identifying the primary function of each organ system listed in the problem.
Consider the role of the respiratory system: it is primarily responsible for gas exchange, bringing oxygen into the body and removing carbon dioxide.
Examine the nervous system: it is responsible for transmitting signals throughout the body to coordinate actions and responses.
Look at the digestive system: it is responsible for breaking down food and absorbing nutrients.
Finally, analyze the circulatory system: it is responsible for transporting nutrients, gases, and waste products throughout the body, which matches the primary function described in the problem.
