artiteacher The gas exchange highway
Breathe it in, breathe it out / A tennis court is inside you / Breathe it in, breathe it out
artiteacher A specialized protein in red blood cells carries oxygen throughout your body.
artiteacher Steer a breath through the branching airways to learn how your lungs absorb oxygen.
Lung surface area: The total surface area of both human lungs is roughly equal to the size of a standard tennis court.
A tiny air sac in the lungs where the exchange of oxygen and carbon dioxide takes place. The human lungs contain roughly 300 million of these microscopic structures to facilitate respiration.
How long does a single red blood cell typically spend inside a lung capillary to exchange gases?
In what form is most carbon dioxide transported through the human bloodstream back to the lungs?
By what physical process do oxygen and carbon dioxide pass through the alveolar membrane?
What is the main chemical trigger that tells the human brain it is time to breathe?
What is the approximate total surface area of all the alveoli in a pair of human lungs?
