The low levels of surfactant produced by alveolar epithelium causes:
Correct answer: B. Respiratory distress syndrome
- A. Emphysema
- B. Respiratory distress syndrome
- C. Bronchitis
- D. Asthma
Explanation
Respiratory distress syndrome (RDS) occurs primarily in premature infants who have not yet produced enough surfactant in their lungs. As a result, their lungs have higher surface tension, making it difficult for them to expand and fill with air properly. This leads to respiratory difficulty, shallow breathing, and can result in severe breathing problems and insufficient oxygenation of the blood.

About Digestion
The human digestive system covers the organs from mouth to anus, the movement of food, and the mechanical and chemical breakdown of carbohydrates, proteins and fats. It also includes the roles of digestive enzymes, bile, absorption through intestinal villi, and the assimilation of nutrients by body cells.
