The blood enters the capillaries in single file ( capillaries have very small diameter so blood flow through them as in single line) there by diffusion the food passes towards the cell and waste from the blood enter the blood stream
Organ exchanges take place in an operating theatre.
capillaries
capillaries is where the exchange of materials occur such as; gases,nutrients, hormones, and so on.between the blood and the interstitial fluid.
EF? (Extracellular fluid). i put a ? because i don't quite understand your question. Capillaries.
blood
the blood vessel which allows gas exchange to occur is the capillaries
At the proximal end of capillary, you get the fluid out in the tissue fluid due to blood pressure. At the distal end of the capillary, you get back the tissue fluid due to oncotic pressure of the blood proteins.
exchange of fluid that occurs across the capillary membrane between the blood and the interstitial fluid. This fluid movement is controlled by the capillary blood pressure, the interstitial fluid pressure and the colloid osmotic pressure of the plasma. Low blood pressure results in fluid moving from the interstitial space into the circulation helping to restore blood volume and blood pressure.

CAPILLARIES.
Exchange of wastes occur's in Capillaries.
Peritoneal dialysis.
When the partial pressure between the alveoli and the blood, or between the blood and the tissues, is different - i.e. when a concentration gradient exists.
