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.
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.
Primary broncioles.

tracheal system
The tubes in the lungs primarily refer to the bronchial tree, which consists of the bronchial tubes branching from the trachea into the lungs. These tubes facilitate the passage of air to and from the alveoli, where gas exchange occurs. The bronchial tree includes the primary bronchi, secondary bronchi, and tertiary bronchi, each progressively branching into smaller bronchioles. Proper function of these tubes is essential for effective respiration and oxygen delivery to the body.
