Where are the bronchi?

Human breathing is inseparable from the trachea. If the trachea is damaged, it will cause breathing difficulties and directly threaten the patient's life. Weather changes or some diseases will irritate the trachea, so everyone should do a good job of protecting the trachea to avoid symptoms of bronchitis. This disease will bring inconvenience to the patient's life. So where is the bronchi?

First, where are the bronchi? The segmentation of the left and right bronchi is determined according to the segmentation of the left and right lungs. Due to the asymmetry of the human lungs, the left and right segments are different, and the segmentation of the bronchi has the same name as the lung segments, such as the anterior bronchus of the left lung, the middle bronchus of the right lung, etc. The left lung is divided into upper and lower lobe bronchi. The left upper lobe bronchus first divides into upper and lower bronchi. The upper branch is then divided into the posterior apical segment and the anterior segment, and the lower segment is also called the lingual branch, which is divided into the upper lingual segment and the lower lingual segment. The left lower lobe bronchus is divided into three basal branches: internal anterior, external, and posterior. That is to say, the left lung does not have a middle bronchus, only the right lung has one, which is the bronchus located in the middle section of the right lung.

Second, what is the cause of bronchitis? Lack of vitamins. Vitamin C is not only good for beauty but also very important for enhancing body's resistance. Vitamin C deficiency will reduce body's resistance. Vitamin A deficiency will weaken the repair function of columnar epithelial cells and mucosa of bronchial mucosa, making it easy to suffer from chronic bronchitis. Long-term smoking. It is common knowledge that smoking is harmful to health, but there are still many people like this in life. Cigarettes contain chemicals such as tar, nicotine and hydrogen cyanide, which can damage airway epithelial cells, reduce ciliary movement and macrophage phagocytic function, leading to decreased airway purification function and a high possibility of chronic bronchitis.

Where are the bronchi? The above content introduces them. Other causes of bronchitis include poor nutritional conditions. Poor nutritional conditions are also a cause of bronchitis. Insufficient protein intake leads to low protein levels in the blood, resulting in less formation of antibodies against microorganisms and low resistance to microorganisms. Immunity will be reduced, making you more susceptible to chronic bronchitis. Living environment. Generally, the incidence of chronic bronchitis is very high in crowded places with poor heating conditions and poor ventilation. Because the air is not circulating, some bacteria or microorganisms will reside there for a long time, increasing the chance of getting sick.
