Physiological buffers | respiratory mechanisms and urinary mechanisms |
Blood colloid osmotic pressure | Force of osmosis that draws water into the plasma (from the presence of colloid particles in plasma) |
Blood hydrostatic pressure | Force of the blood pushing outward on blood vessel walls; blood pressure |
extracellular fluid | Any fluid outside cells, such as interstitial fluid (IF) or blood plasma |
Intracellular fluid | Fluid inside the cell (cytosol) |
Interstitial fluid | Fluid between tissue cells |
Interstitial fluid colloid osmotic pressure | Force that draws water out of the blood and into tissue spaces (from the presence of colloid particles in IF) |
