Because alveoli have to be able to exchange gases freely like oxygen and get rid of carbon dioxide. Also, oxygen must have moisture to benefit breathing.

How does exchange of gases takes place in unicellular organisms?
Gas exchange takes place at a respiratory surface-a boundary between the external environment and the interior of the organism. For unicellular organisms the respiratory surface is governed by Fick's law, which determines that respiratory surfaces must have:a large surface areaa thin permeable surfacea moist exchange surface.Read more: How_does_gas_exchange_take_place
What is required in all living things in order for gas exchange to occur?
In any living organism that needs to breath, the only thing consistently required for life is the presence of moist membranes. The movement of oxygen and carbon dioxide across the membranes between the environment and the respiratory surface occurs by diffusion. Respiratory surfaces are generally thin and, since living animal cells must be wet in order to maintain their plasma membranes, these respiratory surfaces must be moist.
Why do amphibians need moist skin?
Amphibians need moist skin to be able to easily adapt to dry land or the water. This is because an amphibian's respiratory system must be able to adapt to either condition and thin, moist skin makes this easier.
Which of the major plant divisions contains that must live in a moist environment because they do not have a system for conducting water throughout the organism?
mosses/ Bryophyta
What would grow in a mossy area?
To grow moss you need a cool, dark surface and environment (shady) and it also must be moist

Describe all the ways the earthworms are like humans?
Earthworm are like human cause they have a complete losed circulatory system. The earthworm has red blood that contains respiratory pigment similar to hemocfokin. External respiration in human must be moist and an earthworm keep its body surface.

What Must Happen to Cause A Response in an Organism?
Something must change in the internal or external environment of the organism. This change can be physical or chemical and will result in a response from the organism. The scientific name for these changes are stimuli (singular = stimulus), examples of which are touching a hot surface, being scared, exercising and drugs. Hope this helps
What are the advantages of water as respiratory media to aquatic animals?
If an animal lives in the water, it is an advantage to be able to get oxygen from the water. If the animal must breathe air, then it has to surface frequently. If it is unable to surface for some reason, it will drown.
How do you dress the exposed intestines or organ?
You must cover it with moist saline dressings.
In order for clouds to form the air must be what?
The air must be moist.
Why must fern live in moist environment?
Ferns live in moist environments to transport water to cells.
