Why right side of bronchus is more susceptible to foreign body dislodging?

There are several reasons why the right side of the bronchus is more susceptible to foreign body dislodging:

1. Anatomic Factors: The right bronchus is wider and straighter compared to the left bronchus. This makes it easier for foreign objects to enter and become lodged in the right bronchus.

2. Gravity: Due to the gravitational pull, foreign objects tend to fall or drift towards the right side of the body, including the right bronchus.

3. Cough Reflex: The cough reflex is an essential protective mechanism that helps expel foreign objects from the respiratory tract. However, the right bronchus has a weaker cough reflex compared to the left bronchus. This reduced reflex activity may result in a decreased ability to expel foreign bodies from the right bronchus.

4. Bronchial Anatomy: The branching pattern of the right bronchus is more complex compared to the left bronchus, with several smaller branches originating from it. This increased complexity creates more opportunities for foreign objects to become trapped and lodged within the right bronchus.

5. Respiratory Patterns: During normal breathing, the right lung receives a slightly greater volume of air compared to the left lung. This increased airflow can carry foreign objects deeper into the right bronchus, making it more susceptible to foreign body aspiration.

6. Frequency of Food Particles Entering Right Bronchus: The right bronchus is located closer to the esophagus than the left bronchus. When people eat or drink, food particles can accidentally enter the trachea and be directed towards the right bronchus due to its proximity, leading to a higher risk of right-sided foreign body aspiration.

It's important to note that foreign body dislodging can occur in both the right and left bronchi. However, the factors mentioned above contribute to the increased susceptibility of the right side to foreign body aspiration and subsequent dislodging.
