alveoli
I believe the smallest are the alveoli (air sacs), since there are millions of them in the lungs.
there are millions of air sacs in your lungs
alveoli
Because it contains, millions of tiny shards of glass, which can get into your lungs. Is so it can shred your lungs to pieces.
It is to increase the surface area of the lungs so that more oxyen can be taken in.
Alveoli. Singular is alveolus. You have millions of alveoli in your lungs.
Lungs are made up of millions of alveoli and bronchial tubes.
Alveoli
That is not possible. The fluid is collected in millions of very small air spaces.
Alveoli are tiny sacs of air located in your lungs. There are millions of them in your lungs, and they fill up with oxygen when you inhale. They greatly increase the surface area of the lungs so that more oxygen can enter your bloodstream.
They absorb oxygen, then release carbon dioxide. Like a sponge, it absorbs water, and releases the soap and water mixture.
Lungs are made up of millions of alveoli to maximize surface area for gas exchange. Alveoli are tiny, balloon-like structures that facilitate the diffusion of oxygen into the bloodstream and the removal of carbon dioxide. This large surface area, combined with their thin walls, allows for efficient oxygen uptake and carbon dioxide release, which is essential for effective respiration. The vast number of alveoli ensures that the lungs can meet the body’s oxygen demands during various activities.
