Lungs are made up of air-filled sacs, the alveoli. They do not collaps...
The correct answer is option 'B', i.e., Residual volume.
Explanation:
The lungs are made up of air-filled sacs called alveoli. These alveoli are responsible for the exchange of gases between the body and the environment. During breathing, air enters the lungs through the trachea and bronchi and reaches the alveoli. The oxygen from the air diffuses into the bloodstream, and the carbon dioxide from the bloodstream diffuses into the alveoli to be expelled out of the body during exhalation.
The alveoli are surrounded by a network of elastic fibers and a thin layer of fluid. These elastic fibers help in keeping the alveoli inflated, and the fluid helps in reducing the surface tension. This combination of elastic fibers and fluid prevents the alveoli from collapsing during exhalation.
However, there is always some air left in the lungs, even after forceful exhalation. This residual air is called the residual volume. The residual volume is the amount of air that remains in the lungs after the maximum expiration. This volume of air helps to keep the lungs partially inflated and prevents the collapse of the alveoli.
Therefore, the correct answer is option 'B', i.e., Residual volume.
