The branching tubes within the lungs end at small alveoli.
Fmd
Yes, in the Lungs at the base of the multi-branching tracheal tubes within the Alveoli.
Bonchioles
They are called the bronchiThe smallest [air] tubes in the lungs are the broncioles they terminate the larger bronchi.Inside your lungs the two bronchi tubes divide into small bronchial tubes. The bronchial tubes then divide into bronchioles, which are even smaller air passages. Tiny air sacs, called alveoli, are on the ends of the bronchioles.The small tubes located within the lungs are known as the bronchial tubes. The bronchial tubes function is to purify the air that is going into the lungs, when the bronchial tubes become inflamed and swell, Asthma attacks can occur.
Because branching into smaller and smaller tubes increases the surface area that the lings have to enable them to absorb oxygen.
Brachea
The bronchial tubes (or bronchi) are the large tubular structures within the lungs. These carry air into the lungs from the trachea. They branch into smaller tubes called bronchioles, and then to the smallest tubes that contain the alveoli (air sacs) of the lungs.
Bronchi
Bronchi
The two branching tubes in the respiratory system are the bronchi. They are branches of the trachea.
The bronchial tubes connect the trachea and the lungs. Air moves through these tubes into and out of the lungs.
The Primary Bronchi.
