Document Summary
Water is a polar solvent: solvent: a fluid in which in one or more substances dissolve, polar: molecules that has positive and negative charges at polar. Blood 90% water = oxygen transportation and nutrients while removing co2 and waste. Body 60% water (intracellular fluid) = lubricant and cleanser spinal fluid, saliva, tears, synovial fluid (join lube) Water helps regulate temperature by holding heat and changing temperature slowly. Condensation: taking out h20 to form bond. Hydrolysis: taking in water by molecule to break bond. Blood ph 7. 35-4. 5: acidosis (to much acid) 6. 8 lower is death: akylosis (to much base) When you drink (intake): blood volume high and solute concentration low (osmosis) Regulation of output: adh: antidiuretic hormone kidneys increase water reabsorption body water conserved: when blood volume, solution concentration, vice versa. Electrolytes: sodium, potassium and chloride: distribution of electrolytes affects the distribution of water in body. The concentration of na+ is higher outside cells.
