Why gas exchange surface like the alveoli in your lung are always moist?

In order for gas exchange to occur in the alveoli there must remain a constant supply of hemoglobin. Oxygen binds to hemoglobin and if these surfaces were dry then there wouldn't be any hemoglobin.

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.
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.
Why do mammals have large numbers of alveoli?
There are about 300 million alveoli in each of your lungs. These tiny air sacs provide an ideal site for the diffusion of gases into and out of the blood.The alveoli have a very large surface area. In fact if all of the alveoli in your lungs were spread out flat they would cover the area of a tennis court. This large surface area is the result of all the alveoli being small spheres. It is another example of the importance of the surface area: volume ratio.
How are alveoli adapted to maximise diffusion?
The key is surface area. The indentations make the surface area of the lungs inner surface to be many times the surface area of a similarly sized sphere. The greater surface area means that the diffusion distance from the air cavity in the lung to the vascular part of the lung is very short.
What is the effects of the exchange of oxygen and carbon dioxide between internal leaf cells and the external environment?
the surface of these cells are moist and the stomatas are open
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.
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.

what is something natural that is about 7 m high?
exchange gases through their moist body surface ?
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
What is the avioli?
Well, first of all they're called the 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.
