Question

List down the pathway of inhaled air through the respiratory system in the correct order.​

Answer 1

• Respiratory system starts with the nose.
• The inhaled air enters our body through the nose, which has two tiny openings known as the nostril.
• The air then reaches the nasal cavity, which has slimy mucus and a lining of hair, which traps the unwanted dust and foreign particles.
• The air then passes through the common opening for food and air known as the pharynx.
• It then reaches the windpipe/ trachea.
• At the end, the trachea is divided into two to reach the lungs.
