11. Which part of human body maintains the body temperature? [M.P.P.C.S. (Pre) 1991]

Correct Answer: (b) Lungs
Note:

The lungs are the main respiratory organ, which maintains the body temperature through breathing, inhaling oxygen-rich air and exhaling air filled with carbon dioxide which is a waste gas. In this process, energy is produced in tissues by oxidation of foods and the water of the body is vaporised, which maintains the body temperature.
