Explanation:

The nose in the respiratory system has several functions. One of its key roles is to filter out large particles from the inhaled air. This is done by the nasal hairs and mucus present in the nasal cavity.

• The nose does not release oxygen into inhaled air as oxygen is already present in the air we breathe.
• It moistens inhaled air, not exhaled air.
• It warms inhaled air, not cools it.
• Absorbing oxygen from inhaled air is mainly the function of the lungs, specifically the alveoli.

Answer:

Filter out large particles
