the elderly and the very young | are more likely to experience severe consequences with even minor changes in the fluid balance |
the four main functions of water in the body | vehicle for transportation of substances to and from the cells`/ aids in heat regulation/ maintain hydrogen balance/ serves as a medium for the enzymatic action of digestion |
intracellular fluid | fluid within the cell is considered to be in one compartment |
extracellular fluid (ECF) | fluid outside the cell. |
the kidneys | fluid is mainly excreted by this organ |
Avenues of intake of water in 24 HRS | oral fluids 1500ml/ food 800ml/ metabolism 200ml to total 2500ml |
Avenues of Output of water in 24 hours | urine 1500ml/ perspiration 400ml/ feces 200ml/ expired air 400ml to total 2500ml |
control of fluid balance is managed by: | the thirst mechanism/ anti diuretic hormones (ADH)/ aldosterone and atrial natriuretic peptide (ANP) and baroreceptors in the carotid sinus and aortic arch |
Extracellular Fluid | approximately 1/2 of total body water. transports water, nutrients, oxygen, waste. to and from cells. regulated by renal, metabolic, and neurological factors. High Sodium content |
Intravascular Fluid | fluid within the blood vessels. consists of plasma and fluid within blood cells. contains large amounts of protein and electrolytes. |
Interstitial Fluid | fluid in the spaces surrounding the cells. high in Sodium content |
Transcellular Fluid |
