Questions & Answers

Q: Why are lungs important and widely studied?

Lungs are essential because they form the core of the respiratory system, which ensures our survival. They are studied extensively to understand respiratory diseases and develop treatments.

Q: What is the function of the nasal cavity?

The nasal cavity warms, moistens, and filters inhaled air. It also contains sensitive cells responsible for the sense of smell.

Q: What is the purpose of the pharynx?

The pharynx acts as a common passage for air and food, ensuring that food enters the digestive tract and not the respiratory tract. It also helps in swallowing.
