The functions of the respiratory system include:

  • to deliver oxygen to the body.
  • to remove carbon dioxide from the body.

The other options, "to pump blood to the body" and "to absorb nutrients," are not functions of the respiratory system. The pumping of blood is the function of the circulatory system, and nutrient absorption primarily occurs in the digestive system.
