After the trachea, the bronchial tree begins, branching 23 times over the distance to the alveoli, forming the branches of the bronchial tree. The bronchial tree is a special ventilation system in humans, which becomes smaller and narrower as it reaches the lungs, and the respiratory bronchioles connect to the alveoli. The narrowing of these tree-like structures to this extent ensures that air reaches the alveoli easily and completely during breathing. Respiratory laws are provided by tissue structures on the wall of the bronchi: the covering epithelium and their secretions clean and warm the air from the foreign bodies, the glands in the mucous membrane synthesize a mucus substance, absorb the foreign bodies contained in the air, the smooth muscle layer ensures that the amount of air entering the bronchial cavity, its level of penetration into the alveoli The cartilaginous rings of the trachea ensure that the bronchial tubes maintain a tubular structure and do not stick together during exhalation. These physiological processes take place from the birth of a child to the age of one year to ensure the growth of the body, the speed of breathing, the amount of air entering the lungs, the content of which regularly develops and evolves to carry out purification from foreign bodies.
