Notes

The term "Broch" is not commonly used in medical terminology. However, it may be a typographical error or a misinterpretation of the term "Bronchus". The bronchus is a major air passage of the lungs that diverges from the windpipe. In this article, we will explore the anatomy, function, and clinical significance of the bronchus.

Anatomy

The bronchus is part of the respiratory system and serves as a passageway for air to move from the trachea into the lungs. The trachea divides into two main bronchi: the right main bronchus and the left main bronchus. Each main bronchus then branches into smaller bronchi and bronchioles within the lungs.

Right Main Bronchus

The right main bronchus is wider, shorter, and more vertical than the left main bronchus. It divides into three secondary bronchi, each supplying a lobe of the right lung.

Left Main Bronchus

The left main bronchus is narrower, longer, and more horizontal than the right. It divides into two secondary bronchi, each supplying a lobe of the left lung.

Function

The primary function of the bronchi is to conduct air from the trachea into the lungs. The bronchi also play a role in filtering, warming, and humidifying the air before it reaches the delicate tissues of the lungs.

Clinical Significance

Diseases affecting the bronchi include bronchitis, asthma, and bronchiectasis. These conditions can lead to symptoms such as coughing, wheezing, and difficulty breathing.

Bronchitis

Bronchitis is an inflammation of the bronchi, often caused by infection or exposure to irritants such as tobacco smoke.

Asthma

Asthma is a chronic condition characterized by inflammation and narrowing of the airways, including the bronchi, leading to episodes of wheezing and shortness of breath.

Bronchiectasis

Bronchiectasis is a condition where the bronchi are permanently dilated, often due to chronic infection or inflammation.
