Why gas exchange surface like the alveoli in your lung are always moist in youtube?
The alveoli in the lungs are always moist to facilitate efficient gas exchange. This moisture helps dissolve oxygen and carbon dioxide, allowing them to diffuse more easily across the thin alveolar membrane. Additionally, the presence of a liquid film reduces surface tension, preventing the alveoli from collapsing and ensuring they can expand fully with each breath. Overall, moisture is crucial for maintaining optimal respiratory function.

Why gas exchange surface like the alveoli in your lung are always moist?
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 keep the alveoli from collapsing?
Alveoli does not collapse because lungs always have a residual volume which prevents the alveoli to collapse.
Why the concentration of oxygen is always higher in the alveoli than in the blood?
The concentration of oxygen is higher in the alveoli than in the blood due to the process of gas exchange that occurs in the lungs. When air is inhaled, oxygen diffuses into the alveoli, creating a higher partial pressure of oxygen there. This difference in partial pressure drives oxygen from the alveoli into the blood, where it binds to hemoglobin in red blood cells. As a result, the oxygen concentration in the blood increases until equilibrium is reached, but it remains lower than in the alveoli to facilitate continuous diffusion.
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.
Why is water always lost from the gas exchange surface?
Water is lost from the gas exchange surface of terrestrial organisms because gases must be exchanged with air. Terrestrial organisms have a high water potential, therefore when the gas exchange occurs water will be lost.
Do you watch youtube poop?
Always.
Are YouTube fans always 18?
no
In the lungs is carbon dioxide more concentrated in the alveoli or in the blood?
In the lungs, carbon dioxide is concentrated more in the blood. The alveoli keeps the carbon dioxide at a lower level than in the blood.
