Question

Why does cold air need to be warmed by the nasal cavity and the sinuses? To make it easier to filter out pathogens. To increase the pressure of air in the lungs. To protect the alveoli from being damaged. To help prevent pain when breathing in the air.

Answer 1

The nasal cavity and sinuses warm the air before it reaches the lungs. This is because the air needs to be at the right temperature to prevent damage to the delicate tissues in the respiratory tract. The warming of the air also helps to increase the pressure of air in the lungs, which is necessary for proper lung function. This process does not directly help to filter out pathogens, protect the alveoli from being damaged, or prevent pain when breathing in the air. Therefore, the correct answer is "To increase the pressure of air in the lungs."
