capillaries are the site of exchange of materials where the needed substances in the tissue diffuse into them from the capillary through diffusion.while the metabolic wa
ste from tissues diffuse into the capillary and taken away.the capillaries have a big surface area and their cells is one cell thick to enable diffusion to take place fast.
it is because the epithelial cells that make up capillaries are extremely thin allowing substances to pass in and out easily through the gaps of where the epithelial cells are joined.
Blood capillaries are especially adapted to facilitated the exchange of oxygen between the blood and tissues.
They exchange water, oxygen and carbon dioxide, as well as nutrient and waste chemical substances between blood and surrounding tissues.
In the lungs - specifically, the alveoli.
Blood releases its oxygen into the tissues at the capillary level.
To bring about the exchange of oxygen and carbon dioxides between the blood, the air, and tissues.
respiratory system
Exchange of carbon-di-oxide for oxygen takes place between capillaries and tissues.The exchange of gases occur through diffusion.In Lungs, oxygen from inhaled air in the alveolar space moves into the RBCs in the capillaries and the carbon-di-oxide moves form the RBCs in the capillaries to the alveolar space which is exhaled during respiration.In other tissues, the Oxygen is given to the tissues and carbon-di-oxide is taken from the tissues into the blood.Many gases can be exchanged across the capillaries but the exchange of oxygen and carbon-di-oxide occurs normally in the body.

Oxygen and Carbon Dioxide.
the air sacks
Respiration is a process of gas exchange. Respiration is necessary to supply cells with oxygen for metabolism and to remove the waste by product carbon dioxide.
Yes, they do. Just as humans do.
All arteries carry blood to the arterioles, which in turn carry blood to the capillaries, where oxygen exchange in the tissues takes place.
