Concept explainers
Interpretation:
The comparison of blood pressure with the interstitial fluid pressure in arterial capillaries and with the interstitial fluid pressure in venous capillaries has to be given.
Concept Introduction:
Body fluids: About
Intracellular fluid: The fluid inside the cells.
Extracellular fluid: The fluids outside the cells and it include mainly plasma and interstitial fluid.
Passive diffusion is the movement of solutes which can cross the membrane freely and move from regions of high solute concentration to the region of low solute concentration.
