Lung Anatomy and Function Assessment

The video explains the process of respiration, detailing how air enters through the nose, travels down the trachea, and reaches the bronchi and bronchioles before ending in the alveoli. It describes the gas exchange process where oxygen is absorbed and carbon dioxide is expelled. The oxygen-rich blood then circulates to the heart and is pumped throughout the body.

What is the correct order of air passage from the nose to the alveoli?

• Nose, trachea, bronchi, bronchioles, alveoli

• Nose, bronchi, trachea, bronchioles, alveoli

• Nose, trachea, bronchioles, bronchi, alveoli

• Nose, alveoli, bronchi, trachea, bronchioles
