Air passages that are so small they can be seen only through a microscope. They serve the same purpose as the bronchi.
Smaller branches of air passages leading from the bronchi to the alveoli (the small air sacs within the lungs, through the walls of which gas exchange between the blood and air occurs).
Tiny air passages (too small to be seen except through a microscope) that serve the same purpose as the bronchi.
the branches formed from the bronchi.
One of approximately six sets of increasingly smaller airways branching from the bronchi.
The small tubes forming the airways that travel deep into the lungs. They extend from the two bronchi (branches of the windpipe) and they end in small air sacs called alveoli.
smaller respiratory passages in the lungs branching from the bronchi
The smaller air passages in the lungs that branch off of the bronchi.
are the tiniest bronchial tubes. Each lung has about 30,000 bronchioles that are about the same thickness as a hair.
The smaller airways located within the lungs branching off from the Bronchi.
Little tubes that branch off from the larger bronchial tubes.
The smaller airways that take air from the bronchi to the lungs. About 24 bronchioles branch off each bronchi and go deep into the lungs, delivering air to the alveoli
The smallest airways in the lungs.
Small tubes in the lungs that are formed by the branching of the bronchi; terminate in the alveoli.
a subdivision of the bronchial tubes.
are smaller tubes that connect the bronchi and carry air to the alveoli.
Smaller air passages of the lungs.
bronchi are the larger tubes that carry air in the lungs. Bronchioles are the tiny tubes that carry air to the outer parts of the lungs.
One of the millions small end-branches of the bronchi, which transports oxygen.
the tiniest branches of the bronchial tree, they lead into the alveoli.
These smaller tubes branch off from your baby's bronchial tubes.
The smallest subdivisions of the airways within the lungs.
the many small, branching tubules into which the bronchi subdivide Humans as organisms
The tiny branches of air tubes in the lungs.
The tiniest brochial tubes in the lungs; there are about 30,000 of them in each lung; each one is about the thickness of a hair
