Verified step by step guidance
1
Begin by identifying the primary function of each organ system listed in the options.
Consider the circulatory system: its main role is to transport blood, which carries nutrients, gases (such as oxygen and carbon dioxide), and waste products throughout the body.
Next, evaluate the respiratory system: its primary function is to facilitate the exchange of gases (oxygen and carbon dioxide) between the body and the environment, not to transport them throughout the body.
Examine the nervous system: it is responsible for transmitting signals throughout the body to coordinate actions, but it does not transport nutrients, gases, or waste products.
Finally, consider the digestive system: its main function is to break down food and absorb nutrients, but it does not transport these nutrients throughout the body. Based on these evaluations, the circulatory system is the correct answer.
