the blood vessel which allows gas exchange to occur is the capillaries
Capillaries
gases exchange .to release heat.
capillaries and tissue cells
capillaries
capillaries
This process occurs through the capillaries. Nutrients and oxygen diffuse from the blood into the tissues, while waste products and carbon dioxide diffuse from the tissues into the blood. This exchange is facilitated by the thin walls of the capillaries and the high surface area for diffusion.
External respiration is the exchange of gases between each lung and blood. It involves inhaling gases from the organisms external environment, and then exhaling the gases back out.
Oxygen passes from the air sacs in the lungs to the blood in the capillaries, carbon dioxide passes the other way.
This body system that is responsible for the exchange of gases between the blood and the external environment.
The velocity of blood is slowest in the capillaries. This allows for maximum exchange of nutrients, gases, and wastes between the blood and the surrounding tissues.
To allow Oxygen to travel to every Cell in a living organism there is a gas exchange between nearby Capillaries and the cells of that organism.The same exchange works the other direction to take away waste products of cell living
