Bronchi
The branching tubes within the lungs end at small alveoli.
The respiratory system of insects is called the tracheal system. It consists of a network of branching tubes called tracheae that deliver oxygen directly to the cells and remove waste gases. These tubes have openings called spiracles on the surface of the insect's body.
Bronchoscope.
They are called Fallopian tubes
Lungs have branching structures called bronchial tubes that resemble the branches of a tree. The bronchial tubes divide and become smaller, similar to how tree branches branch out into smaller twigs. This branching network in the lungs allows for efficient air distribution and gas exchange.
The Primary Bronchi.
Primary broncioles.
The two branching tubes in the respiratory system are the bronchi. They are branches of the trachea.
there are no 'tubes' as such in your heart; they are called chambers. the two chambers at the top are called atria and the two at the bottom are called ventricles. :D
