Definitions:

Alveoli

Tiny air sacs in the lungs where the exchange of oxygen and carbon dioxide takes place, crucial for the respiratory process.

Gas Exchange

The biological process through which gases (such as oxygen and carbon dioxide) move between the environment and the bloodstream, typically through the lungs or gills.

Bronchioles

Small passages in the lungs that lead from the bronchi to the alveoli, facilitating the movement of air in and out of the lungs.

Hypoventilates

To breathe at an abnormally slow rate, leading to increased carbon dioxide levels in the blood, potentially causing respiratory acidosis.
