Gas exchange surfaces like the alveoli need to be moist because gases, such as oxygen and carbon dioxide, dissolve in water. The thin layer of moisture in the alveoli allows for efficient exchange of gases between the air in the lungs and the bloodstream. This ensures that oxygen can be absorbed into the blood and carbon dioxide can be released from the blood.

What has thin walls moist surface and good blood supply?
The alveoli in the lungs have thin walls, moist surfaces, and a rich blood supply. This anatomy helps facilitate the exchange of oxygen and carbon dioxide during the process of respiration.
Why respiratory surface of all organism must be moist?
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.
Why do mammals have large numbers of alveoli?
Mammals have large numbers of alveoli in their lungs to increase the surface area available for gas exchange. This allows for efficient exchange of oxygen and carbon dioxide between the lungs and the bloodstream. The more alveoli present, the more oxygen can be absorbed into the bloodstream and the more carbon dioxide can be expelled from the body.
What structure is adapted for the diffusion of gases?
The lungs have been adapted especially for making gas exchange more efficient. They are made up of clusters of alveoli, which are tiny air sacs with large surface areas, and are kept moist. They also have a rich blood supply, which maintains a concentration gradient in both directions. Carbon dioxide constantly being removed from the blood and oxygen constantly entering the lungs means that gas exchange happens at the highest concentration gradients to make it rapid and effective.
What is the function of the moisture layer inside an alveolus?
The moisture layer inside an alveolus helps to keep the surface moist, facilitating the exchange of gases (oxygen and carbon dioxide) between the alveoli and the blood vessels. This layer also helps to prevent the alveoli from collapsing by reducing surface tension.
Why do gas exchange surfaces need to be moist?
The gases are to dissolve and diffuse through.
The thin moist membrane through which humans exchange gases is found in the what?
alveoli

Adaptive feature of trachea and alveoli?
Trachea have cartillage rings which support it. And the Alveoli has large surface area for diffusion and its moist and thin.
How does gas exchange take place?
Gas exchange takes place in the lungs, where oxygen from inhaled air diffuses into the bloodstream and carbon dioxide from the bloodstream diffuses into the alveoli to be exhaled. This exchange occurs through the process of diffusion across the thin walls of the alveoli and capillaries.
What are the functions of alveoli?
Alveoli are tiny sacs in the lungs that perform gas exchange. That is the main process of respiration where the body gets rid of carbon dioxide and picks up oxygen which is used in metabolism. They have supply of oxygenated and de-oxygenated blood surrounding their surface giving them a high blood supply. They also have thin walls and a moist surface. This is all required for them to work correctly.

Why is the lung squishy?
The lung has to constantly expand and contract during the exchange of gases. Besides, the alveoli of the lung has to be moist and spongy in order to maximize the surface area to effect the maximum transfer of gases.
How do alveoli and capillaries help to get oxygen?
The alveoli is the point where the waste product of respiration (carbon dioxide) and oxygen are diffused into or out of the blood. Oxygen diffuses into the blood stream and are carried to the heart and carbon dioxide is diffused out of the lungs and expired. The alveoli have moist walls and are close to the capillaries which speeds up the process.
Explain the relationship between structure and function.use alveoli as an explain.Be sure to include more that one level of organization?
alveoli are arranged in grape like groups to increase surface area in which gas exchange takes place, the walls are very thin just big enough for on cell to pass so that there is an increase in rate of diffusion, walls of alveoli are moist so it also increases the rate of diffusion and the alveoli can stretch so that it prevents the alveoli form over filling with air and damaging the thin walls
