The function of the Immune System is to respond when pathogens enter the body.  The Immune System is not responsible for exchanging oxygen and carbon dioxide, that is the job of the Respiratory System.  It also does not provide structure for the body, that is the role of the Skeletal System.  And finally, the Excretory System is responsible for the removal of waste.

Darina [25.2K]

Smoking have life-threatening effects on a smoker's lungs. A smoker is at a high risk of lung cancer and chronic obstructive pulmonary disease. In order for a coach to explain the destructive effects of smoking on the performance of the athletes, it is best to show a diagram of the flow of the oxygen-rich blood in a non-smoker's body and then the flow of blood with less-oxygen in smoker's body. This will show the difference between the two situations clearly, and show how the airway resistance effects the performance of a person.

Hence, the answer is 'option C - Diagram the flow of oxygen-rich blood in non-smoker's body and the, diagram of flow of blood with less oxygen in smoker's body'.
