Three processes are essential for the transfer of oxygen from the outside air to the blood flowing through the lungs: ventilation, diffusion, and perfusion. Ventilation is the process by which air moves in and out of the lungs.

- Overview of The Respiratory System
Gas exchange allows oxygen to travel into your cells for respiration whilst also removing carbon dioxide, which is a waste substance made by the process of respiration.
Gas exchange is the process by which oxygen and carbon dioxide move between the bloodstream and the lungs. This is the primary function of the respiratory system and is essential for ensuring a constant supply of oxygen to tissues.
Learn how oxygen and carbon dioxide move across the respiratory membrane in the alveoli, and how ventilation and perfusion affect gas exchange. Understand the gas laws, solubility, and partial pressures that govern the process of gas exchange.
10 Απρ 2022 · Learn how oxygen and carbon dioxide move between the bloodstream and the lungs, and the factors that affect the rate of diffusion. Explore the physics of gas diffusion, the diffusion barrier, and the clinical relevance of emphysema.
30 Ιουλ 2022 · Gas exchange occurs at two sites in the body: in the lungs, where oxygen is picked up and carbon dioxide is released at the respiratory membrane, and at the tissues, where oxygen is released and carbon dioxide is picked up.
The gas exchange system is responsible for getting oxygen into the blood and removing carbon dioxide as a person breathes. Breathing is also called 'ventilation' and is the movement of...
