Introduction to Lung Physiology definitions Flashcards

The process of moving air in and out of the lungs by changing the thoracic cavity volume.

The exchange of gases, specifically oxygen and carbon dioxide, between blood and tissues.

The act of inhaling air into the lungs, primarily using the diaphragm muscle.

The act of exhaling air out of the lungs, typically involving muscular relaxation.

Normal, restful breathing that occurs without conscious effort.

Deeper, more strenuous breathing using additional muscles for both inhalation and exhalation.

Gas exchange between air in the alveoli and blood, involving oxygen and carbon dioxide.

Gas exchange between blood and body tissues, delivering oxygen and removing carbon dioxide.

The metabolic process of breaking down molecules like sugar to produce ATP and carbon dioxide.

The primary muscle of respiration that contracts to increase thoracic cavity volume during inhalation.

The space within the rib cage that changes size to facilitate lung ventilation.

Tiny air sacs in the lungs where external respiration occurs, exchanging gases with the blood.

A blood molecule that increases oxygen and carbon dioxide transport capacity.

The property of the lungs that allows them to expand and recoil naturally.

Refers to the lungs' lack of muscle, relying on external muscles to change size.
