Answer:
Wet lung is a serious condition resulting from the body’s inability to receive enough oxygen to the lungs. If oxygen cannot get into the body’s organs, this can lead to infections, pneumonia, muscle weakness, kidney failure, and other serious and life-threatening complications.
A respiratory surface is covered with thin, moist epithelial cells that allow oxygen and carbon dioxide to exchange. Those gases can only cross cell membranes when they are dissolved in water or an aqueous solution, thus respiratory surfaces must be moist.
