Orderly route air takes into the lungs: nasal cavity > pharynx > trachea > bronchi > bronchioles > alveoli.

Alveoli are the tiny air sacs where oxygen and carbon dioxide exchange occurs.

The two main phases are inspiration (breathing in) and expiration (breathing out).

Inspiration is the active process when muscles contract to draw air in.

Expiration is the passive process where air is expelled without muscular effort.

Units include respiratory bronchioles, alveolar ducts, alveolar sacs, and alveoli.

A test that assesses the status of the respiratory system, evaluating lung function.

Based on measuring the volume of air breathed in and out during quiet and forced breathing.

A spirometer is used to carry out the lung function test.

The total volume of air that can be breathed in by an individual.

Tidal volume, inspiratory reserve volume, expiratory reserve volume, residual volume.

The volume of air breathed in and out during quiet respiration, typically 0.5L.

The maximum amount of air you can forcefully breathe in after normal respiration, around 3.3L.

The maximum volume of air you can forcefully exhale after normal respiration, about 1L.

The volume of air remaining in the lungs after full exhalation, about 1.2L.

The sum of two or more lung volumes together.

Includes inspiratory capacity, vital capacity, functional residual capacity, and total lung capacity.

The maximum amount of air that can be inhaled, calculated as TV + IRV.

The total volume of air that the lungs can hold, around 6L.

The volume of air remaining in the lungs after normal respiration (RV + ERV), about 2.2L.
