They are the place where the capillaries are closest to the environment in order to exchange gases such as oxygen and carbon dioxide.
it absorbs all the poisonous gases in the environment so that supporting the environment from some toxic or harmful gases
yes of course gases such oxygen carbon dioxide methane carbon monoxide sulfur dioxide so and so forth ....
By smoking, the wall of alveolus becomes thin, so it will be damaged with continuous coughing that decreases the surface area of exchanging gases, by this way, the smoker suffers from shortage of oxygen.
Because a system is a group of organs and respiratory has organs.
Nuclear energy provides electricity which is good for humans, and for the environment it does not produce greenhouse gases, so that is good. However it has dangers too, so must be well controlled
the wind farm helps the environment by creating less pollution also it does not create toxic gases so it does not harm most habitats.
You didn't finish your question so we don't know what you're asking. Surround what?
i think so
there are allot of gases go to google
nutrients, carbon dioxide, and oxygen im not sure so you would have to go look it up but this is what i found!!!
there are so many gases
Two gases spread easily through each other because they have low intermolecular forces and high kinetic energy. This allows the gas particles to move freely and mix evenly with other gases in the surrounding environment.
