capillaries
the blood vessel which allows gas exchange to occur is the capillaries
capillaries
gases exchange .to release heat.
Across the alveoli and capillaries.
diffusion across their body surface (cell surface membrane)
they are not
They EXCHANGES GASES The Same Way As We Do. OXYGENEnters Their LUNGS And Exits Out As CARBON DIOXIDE.
All blood vessels allow gases, such as oxygen and nitrogen, as well as liquids, enzymes, etc, to pass through them. Food particles, once absorbed by the small intestines, become part of this process.
The exchange of oxygen and carbon dioxide occurs through the mechanism of diffusion. The gases diffuse across the thin walls of the capillaries, both in the body tissues and in the capillaries surround the alveoli in the lungs.
No, only water molecules move by osmosis. Gases are normally exchanged by the process of diffusion.
The Alveoli in the lungs have a very good capillary network because this is where gas exchange occurs. There needs to be sufficient area to allow the red blood cells to expel their carbon dioxide and to receive oxygen across the capillary and alveoli walls.
