Complete Anatomy of the Bronchi of a person
What is the Bronchi?
Bronchis (bronchus) are called the branches of the respiratory throat (the so-called bronchial tree).
In the area of bifurcation, a protrusion of the wall – the spur (keel) , directed to the left to the left, protrudes from the bottom of the trachea .
The left bronchus departs from the bifurcation point almost at right angles, and the right bronchus is more oblique downward. Accidentally falling into the trachea foreign bodies due to this usually appear in the right bronchus, where they are found during the fluoroscopic examination.
What does the bronchi look like?
Below is the image of Bronchial tree of the right lung (roentgenogram) (according to Kraev, 1978):
1 – trachea;
2 – the main bronchus;
3 – intermediate bronchus;
4 – upper lobe bronchus;
5 – lower lobe bronchus;
6 – segmental bronchus of the upper lobe;
7 – segmental bronchi of the middle lobe;
8 – segmental bronchi of the lower lobe
The main bronchus (first order), entering the gates of the lungs, is divided into the bronchi of the second, third and other orders, which, all decreasing in calibre, form a bronchial tree.
The right bronchus forms three branches, and the left bronchus – two. Each of the branches goes to the lobe of the lung. In the gates of the lungs, the main bronchus and its branches closely touch the arteries that enter the lungs, and with the veins emerging from them. All these tubular formations are surrounded by a dense connective tissue and form the root of the lung.
The bronchial tree includes the main bronchi – right and left, the lobar bronchi (1st order), zonal (2nd order), segmental and subsegmental (3, 4, 5 orders of magnitude), small (from 6th to 15th, th order) and finally, terminal bronchioles, followed by the respiratory departments of the lungs (whose purpose is to perform the gas exchange function).
The structure of the bronchi is not the same throughout the entire bronchial tree, although it has common features.
What is the function of the bronchi and bronchioles?
Bronchi provide air from the trachea to the alveoli and back, and also contribute to the purification of air from foreign impurities and their removal from the body. Large foreign bodies are removed from the bronchi with the help of a cough. And smaller (dust particles) or microorganisms trapped in the respiratory tract are removed with the help of oscillations of the cilia of epithelial cells, which ensure the advance of the bronchial secretion towards the trachea.
In a live patient with bronchoscopy (ie, when examining the trachea and bronchi with the aid of a bronchoscope through the larynx and trachea), the mucosa is greyish in colour; well visible cartilaginous rings. The angle at the place of division of the trachea into the bronchi, having the appearance of a ridge protruding between them, carina, should normally be located along the median line and freely move during respiration.
