capillaries
the blood vessel which allows gas exchange to occur is the capillaries
capillaries
capillaries, which are small blood vessels with thin walls that allow for the exchange of gases, nutrients, and waste products between the blood and tissue cells. This exchange is facilitated by diffusion across the thin capillary walls.
gases exchange .to release heat.
Across the alveoli and capillaries.
At the boundary between the capillaries and the alveoli, gas exchange occurs through a process called diffusion. Oxygen from the alveoli moves into the blood within the capillaries, while carbon dioxide from the blood is released into the alveoli to be exhaled. This exchange happens across the thin walls of the alveoli and capillaries, which are composed of single layers of cells, facilitating efficient transfer due to the concentration gradients of the gases.
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.
