Alveoli
There like tree branches that branch off to the alveoli
the alveoli
it looks like a bunch of grapes ,only on a microscopic level.
the bronchiole
broncheoli are the branches carrying air from the bronchi to the alveoli..
Trachea> Bronchii> Bronchioles (smaller branches of bronchii) > Alveoli
alveoli are tiny branches of the lungs where blood travels to be oxygenated so it is useful to the rest of the body.
it sorta looks like two trees entwined together wit the branches fused together
The alveoli are small sacs within the lungs where gas exchange occurs. They are located at the ends of bronchiole branches.
it means it looks like the branches of a tree
The trachea splits into the left and right bronchi in the thoracic cavity(the chest). From there the bronchi continue to branch out and keep getting smaller. Kind of like the branches on a tree. At the end of the those branches (bronchioles) are the alveoli( tiny grape like structures). In the alveoli is where the exchange of oxygen and carbon dioxide occur.
