Question 10

COPD (Chronic Obstructive Pulmonary Disease) is a group of progressive lung diseases. The two main conditions that make up COPD are chronic bronchitis and emphysema. Pleurisy is inflammation of the pleura, bronchiectasis is a different lung condition involving abnormal widening of bronchial tubes, and asthma is a separate respiratory condition (not part of COPD's main components).

Parietal cells are located in the stomach lining. Their main function is to secrete hydrochloric acid (HCl) and intrinsic factor. Gastrin is secreted by G cells, mucus by goblet cells and mucus neck cells, and pepsinogen by chief cells.

The pharynx is divided into three parts: nasopharynx (for air from nose), oropharynx (receives both food from mouth and air from nose/mouth), and laryngopharynx (for food and air going to larynx/esophagus). "Internal pharynx" is not a standard term. So the oropharynx is the part that receives both food and air.

A. emphysema
