The alveoli.
The alveoli.
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.
The small sacs at the end of the Bronchial tubes are called the anus.PL77 * erm i think you have the wrong organ system, that is the end of the digestive system bronchial tubes are in the respiratory system and the small sacs attached to the bronchial tubes are called alveoli they are air sacs in the lungs*
The bronchial tubes in the lungs divide into smaller branches known as bronchioles, which further subdivide into tiny air sacs called alveoli. This branching pattern resembles the structure of a tree, with the bronchial tubes acting as the trunk and the alveoli as the leaves where gas exchange occurs.
When we breathe in, air travels down into our bodies through the trachea (windpipe) and into the bronchial tubes in our lungs. These tubes branch off into smaller airways called bronchioles, which lead to tiny air sacs called alveoli where oxygen is absorbed into the bloodstream and carbon dioxide is released.

Tubes in the kidney. I'm not sure what they are called, though.
Air enters the body through the nose or mouth, then travels down the windpipe (trachea) into the bronchial tubes in the lungs. The bronchial tubes divide into smaller airways called bronchioles, which lead to tiny air sacs called alveoli where gas exchange takes place. Oxygen from the air passes through the alveoli walls into the bloodstream, while carbon dioxide from the bloodstream passes out into the lungs to be exhaled.
Oxygen enters the body through inhalation, where it passes through the nasal passages or mouth into the trachea. It then travels down the bronchial tubes, reaching the alveoli in the lungs where it diffuses into the bloodstream through tiny blood vessels called capillaries.
Capillaries are the tiny tubes that carry blood. These tubes connect arteries and veins.
