Bronchial tree

Definition

The bronchial tree is a system of air passages that branch off from the trachea into increasingly smaller tubes, leading air in and out of the lungs. It plays a crucial role in the respiratory system by facilitating the movement of air for gas exchange.

The trachea is a large tube reinforced by rings of cartilage, extending from the larynx to the bronchial tubes and conveying air to and from the lungs.

Alveoli:

Alveoli are tiny sac-like structures found at the end of bronchioles in the lungs, where gas exchange between air and blood takes place.

Gas Exchange:

Gas exchange is the biological process through which gases like oxygen and carbon dioxide are transferred between the bloodstream and the lungs' alveoli during respiration
