Question

Which of the following is the correct sequence of air passage during inhalation?

Options

• nasal passage → trachea → pharynx → larynx → alveoli

• larynx → nostrils → pharynx → lungs

• nostrils → pharynx → larynx → trachea → alevoli

Answer 1

nostrils → pharynx → larynx → trachea → alveoli

Explanation:

During inhalation, air enters through the nostrils, passes through the pharynx and larynx, and then travels down the trachea. From there, it moves through the bronchi and bronchioles to reach the alveoli, where gas exchange occurs.
