Moderate tracheobronchomalacia would be 25% of the normal trachea space constricting and a severe case would be if the walls touch each other. [ 10 ] Tracheobronchomalacia is thought to be underdiagnosed as mild cases may be asymptomatic and symptoms are often mistaken for more common respiratory conditions like Asthma and Chronic obstructive ...
A bronchus (/ ˈ b r ɒ ŋ k ə s / BRONG-kəs; pl.: bronchi, / ˈ b r ɒ ŋ k aɪ / BRONG-ky) is a passage or airway in the lower respiratory tract that conducts air into the lungs.The first or primary bronchi to branch from the trachea at the carina are the right main bronchus and the left main bronchus.
The trachea is the largest tube in the respiratory tract and consists of tracheal rings of hyaline cartilage. It branches off into two bronchial tubes, a left and a right main bronchus. The bronchi branch off into smaller sections inside the lungs, called bronchioles. These bronchioles give rise to the air sacs in the lungs called the alveoli. [10]
The trachea and bronchi form the tracheobronchial tree. The trachea is situated between the lower end of the larynx and the center of the chest, where it splits into the two bronchi at a ridge called the carina.
It helps to divide the trachea into two primary bronchi. The right bronchus makes an angle of 25°, while the left one makes an angle of 45°. The carina is a sensitive area. When the patient is made to lie on their left side, secretions from the right bronchial tree flow toward the Carina due to the effect of gravity.

The trachea (pl.: tracheae or tracheas), also known as the windpipe, is a cartilaginous tube that connects the larynx to the bronchi of the lungs, allowing the passage of air, and so is present in almost all animals lungs. The trachea extends from the larynx and branches into the two primary bronchi.
Bronchopulmonary nodes (hilar nodes) situate in the hilum of each lung. Pulmonary nodes are embedded the lung substance on the larger branches of the bronchi. The afferents of the tracheobronchial glands drain the lungs and bronchi, the thoracic part of the trachea and the heart ; some of the efferents of the posterior mediastinal glands also ...
