Bronchitis is inflammation of the bronchi (large and medium-sized airways) in the lungs that causes coughing. Bronchitis usually begins as an infection in the nose, ears, throat, or sinuses. The infection then makes its way down to the bronchi. Symptoms include coughing up sputum, wheezing, shortness of breath, and chest pain.
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.

It is an inflammation of the bronchial tubes. There are two forms of this infection: acute bronchitis, which is treatable and can go away without treatment, or chronic bronchitis, which comes and goes, but will always affect one's lungs. Bronchitis increases the amount of mucus that is natural in your respiratory tract.
Acute bronchitis can be defined as acute bacterial or viral infection of the larger airways in healthy patients with no history of recurrent disease. [8] It affects over 40 adults per 1000 each year and consists of transient inflammation of the major bronchi and trachea. [ 9 ]
An oblique fissure was found to be incomplete in 21% to 47% of left lungs. [48] In some cases a fissure is absent, or extra, resulting in a right lung with only two lobes, or a left lung with three lobes. [46] A variation in the airway branching structure has been found specifically in the central airway branching.
Perfusion is the delivery of oxygen-rich blood to the body tissues through the lymphatic system or circulatory system. [6] The primary function of perfusion is the efficient removal of cellular waste and nutrition supply during gas exchange. Perfusion occurs during heart contraction when the oxygenated blood is pumped into the arteries.
Bronchitis: Bronchitis occurs due to inflammation of the bronchial tubes, often triggered by viral infections or irritants like smoke, leading to excessive mucus production and airway obstruction. Common symptoms include a productive cough, wheezing, mild chest discomfort, and fatigue.
