Document Summary
50- 70% of healthy adult"s body is composed of fluids intracellular fluid 2/3 of our body fluid that is within the cells. Extracellular fluid- the 1/3 that"s outside our body cells. Tissue type: lean tissue have higher fluid content than fat tissue. Gender: males have more lean tissue , so more body fluid. Age: lean tissue is lost with age and so is body fluid. Electrolytes mineral salts: +ve charged :sodium, potassium, ve charged: chloride and phosphorus fluid has an overall neutral charge due to charges balancing out from electrolytes, intracellular fluid: potassium and (hpo4)2, extracellular: sodium and chloride (cid:1) (cid:1) Fluids dissolve and transpot substances: water is a universal solvent and solutes include sugars, amino acids, vitamins and minerals. Blood volume amount of fluid in the blood: increased bv causes high bp, decreased blood volume causes low bp. Temperature: water"s high heat capacity leads to our body"s stable temperature, sweat releases heat from our skin and blood.
