Expert Solution
Lungs are composed of two distinct components. One system is totally composed of tubes to conduct air in and out of lungs. The other is alveoli, site for exchange of oxygen and carbon dioxide between air and pulmonary capillaries. The alveoli are lined by flat squamous cells and large secretory cells that produce a lipid compound called surfactant to reduce surface tension in lungs. The role of surfactant is to prevent the alveoli from collapsing. Option d is correct.
The pulmonary alveoli filled with the fluid or exudate or mucus accumulated due to inflammation do not allow the inspired air to enter and thus, pulmonary gas exchange is obstructed.

At the surface, the average total lung capacity of human lungs
is about 6 liters of air (~0.21 ft3). Free divers
typically fill their lungs with air and hold their breath while
they dive. Assuming that Boyle’s Law accurately reflects changes in
the air volume in a free divers’ lungs, calculate the change in
volume that would occur in a free diver’s lungs at the following
depths below the surface of the ocean: 10m, 20m, 35m, 45m. Finally,
the world...
