Begin by identifying the primary function of each organ system listed in the problem.
Consider the Respiratory system: Its main role is to facilitate the exchange of gases, primarily oxygen and carbon dioxide, between the body and the environment.
Examine the Digestive system: This system is responsible for breaking down food into nutrients, which are then absorbed into the bloodstream.
Analyze the Nervous system: It is responsible for transmitting signals throughout the body to coordinate actions and responses.
Focus on the Circulatory system: This system is primarily responsible for transporting nutrients, gases, and waste products throughout the body via blood vessels, making it the correct answer.
