Alveoli

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

Bronchioles

Small airways in the lungs that lead from the bronchi to the alveolar sacs, responsible for carrying air in and out of the lungs during respiration.

Intubation

The procedure of inserting a tube into the body, typically into the trachea for ventilation purposes.
