Document Summary

Polar: + one end and charge the other end. Osmosis: diffusion of water (area of high concentration to low. Ion: group of atoms that carry an electrical charge. Its an ideal solvent: polarity allows it to surround solvents and disperse them. Water un urine helps remove waste (urea and ketones) Wash away dirt, synovial fluid, saliva, spinal fluid: regulates body temperatures. Water hold on to heat changing temp slowly. Action of blood vessels (hot skin vessels dilate, cold constrict) Hydrolysis adds water, condensation takes away water. Ph= 1-14; 1= acidic; 14 = basic. Most occur at 7. 4 (but all are dif) Water= medium for chem rxns that prevents change in ph: also needed as a transport to allow respiratory tract and kidneys to regulate acid-base balance. Inside cells: highest [protein, high [k], low [na, cl] Extracellular fluid: 1/3 of body fluid, outside of cell, 2 types: Intravascular fluid: fluid in vessels: 2nd highest [protein, high [na, cl], low [k]
