In this question, we will understand the air path from entering the nasal passages to reaching the alveoli, where gas exchange takes place.
<h3>What is the air's path to the lungs?</h3>
The air penetrates through the nasal passages, passes through the pharynx, larynx and trachea, bronchi, reaching the lungs where it travels through the bronchioles until reaching the alveoli, where gas exchange takes place. The difference between inspired and expired air is in the concentration of oxygen and carbon dioxide.
a) Blood leaving the air sacs is rich in oxygen gas.
b) When exhaling, the breath is rich in carbon dioxide.
c) If you trace the path of air moving through the respiratory system, it would enter through the mouth and nose. It continues through the pharynx, into the larynx, through the tubes and into the trachea and finally reaches the lungs.
