Document Summary
50-70% of the health adult body is composed of water and other bodily fluids. (cid:1152) of the total water content is intracellular (inside the cells) (cid:1151) of the total water content is intercellular (outside the cells) Too much volume of water, can increase pressure (blood pressure) Tissue type: lean tissues have higher fluid content than fat tissue, and therefore lean individuals have a higher fluid-body content. Age: lean tissue is lost with age and body fluid is lost with it. Gender: males have more lean tissue and therefore more body fluid. Dissolves and transports nutrients and waste products (water soluble) Maintain structure of large molecules (eg. glycogen) Lubricant (eg. saliva, fluid around the heart and brain) Maintains blood volume, and inherently blood pressure. If we maintain a vessel at a certain size, ad we increase the volume of fluid in this vessel, the pressure increases.
