It defuses throught the respiratory membrane and binds to hemoglobin (in humans) following a hemoglobin type-specific binding affinity curve (depending on the Po2 of the local atmosphere.)
An alveolus is a single air-sac, and alveoli are multiple air-sacs.
Oxygen is needed for aerobic respiration.
Nowhere, animals do not produce oxygen.
Pure oxygen is a gas at 25 C, regardless of the pressure.
this is a good site
The process involved in the passage of gas between the alveolus and the blood is called gas exchange. This occurs through diffusion, where oxygen moves from the alveolus into the capillaries and carbon dioxide moves from the capillaries into the alveolus.
It is carbon dioxide which is collected from different organs of the body by blood
The process in which oxygen enters the bloodstream through the alveolus and carbon dioxide exits the bloodstream also through the same alveolus to be exhaled.
The bronchus of a lung is the tubes leading up to the alveolus of the lung. The alveolus of a lung is the small air sacs at the end of the bronchi (bronchus). The alveoli is where the gas exchange of oxygen and carbon dioxide takes place.
air will burst into flame in pure oxygen
The molecules of the gas will stop moving.
The alveolus is filled with air, which allows for the exchange of oxygen and carbon dioxide between the lungs and the bloodstream. The alveolar walls are lined with a thin layer of fluid that helps facilitate this gas exchange.
the alveolus
It turns into gas
it settles down
Each alveolus is surrounded by a network of capillaries, which are tiny blood vessels responsible for the exchange of oxygen and carbon dioxide with the surrounding tissues. This network allows efficient gas exchange to occur in the lungs.
It undergoes a phase change, and turns to liquid.
