Cartilage rings are gradually replaced by regular plates of cartilage!
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 large tubes in the respiratory system are called bronchi. The trachea branches into two primary bronchi, which then divide into smaller bronchioles that lead to the lungs. These tubes are essential for conducting air to and from the lungs during the process of respiration.
smaller
Respiratory bronchioles, alveolar ducts, and alveoli.
When the diaphragm expands, causes the lungs to become smaller forcing all the air in the lungs to be pushed out since there is more pressure. When the diaphragm contracts, it makes more room for the lungs to expand, forcing air in the lungs since there is more space.
no
These are called alveoli.The bronchi (or air passages) continually divide into smaller and smaller bronchi in the lungs, until they become bronchioles. The very smallest of the bronchioles end in a tiny sac or 'balloon' called alveoli.The alveoli are surrounded by a dense network of capillaries which allows the exchange of gases between the lungs and the bloodstream.alveoli
A bronchus is a passage of airway in the respiratory tract that conducts air into the lungs. The bronchus branches into smaller tubes, which in turn become bronchioles.
In anatomy, doctors refer to the tree-like branches of the lungs as the bronchial tree. This structure includes the main bronchi that branch from the trachea, which further subdivide into smaller bronchi and bronchioles, eventually leading to the alveoli where gas exchange occurs. The bronchial tree plays a crucial role in conducting air to the lungs and facilitating ventilation.

The diaphragm, below the lungs, contracts causing a lower pressure in the lungs, and pulls the air in. To exhale, the diaphragm relaxes, and the chest muscles contract, forcing the lungs to be smaller and the air to be pushed out.
