The waste product of respiration that leaves the alveoli is carbon dioxide, which is produced during the process of cellular respiration. This gas is expelled from the body when we exhale. Other products, such as water and energy, are not considered waste materials. ;
The waste product of respiration that leaves the alveoli is carbon dioxide, produced during cellular respiration. This process converts glucose and oxygen into energy while generating carbon dioxide, which is expelled during exhalation. Hence, the correct answer is C. carbon dioxide .
