You go for a long run on an extremely hot, humid day, and assuch, you sweat way more than you typically would. Describe what isoccurring to the water balance in your body, including:
a. An overview of the differences between the intracellularfluid and the extracellular fluid compartments
b. Movement of water/fluids between the compartments
c. The role of sodium in water balance, how it is regulated, andhow sodium contributes to the bodyâ€™s homeostatic equilibrium
d. Your bodyâ€™s response to the disruption in water balance andhow it is compensated for

1 Intracellular fluid Intracellular fluid is a fluid inside the cell membrane containing dissolved ions and other components Found inside the cell Comprises the cytosol The concentration of sodium ions is low and the concentration of potassium ions is high Comprises 55 of body water Comprises 33 of total body weight Comprises 19 L of total body fluids Extracelluar fluid Extracellular fluid is the fluid found outside of the cell aiding the functioning of a particular tissue Found outside the cell Comprises plasma tissue fluid and transcellular fluid The concentration of sodium ions is high and the concentration of potassium ions is low Comprises about 45 of body water Comprises 27 of total body weight Comprises 23 L of total body fluids 2 Hydrostatic pressure the force exerted by a fluid against a wall causes movement of fluid between compartments The hydrostatic pressure of blood is the pressure exerted by blood against the walls of the blood vessels by the pumping action of the heart In capillaries hydrostatic pressure also known as capillary blood pressure is higher than the opposing colloid osmotic pressure in blooda constant pressure primarily produced by circulating albuminat the arteriolar end of the capillary This pressure forces plasma and nutrients out of the capillaries and into surrounding tissues Fluid and the cellular wastes in the tissues enter the capillaries at the venule end where the hydrostatic pressure is less than the osmotic pressure in the vessel Filtration pressure squeezes fluid from the plasma in the blood to the IF surrounding the tissue cells The surplus fluid in the interstitial space that is not returned directly back to the capillaries is drained from tissues by the lymphatic system and then reenters the vascular system at the subclavian veinsNet filtration occurs near the arterial end of the capillary since capillary hydrostatic pressure CHP is greater than blood colloidal osmotic pressure BCOP There is no net movement of fluid near the midpoint of the capillary since CHP BCOP Net reabsorption occurs near the venous end of the capillary since BCOP is greater than CHP Hydrostatic pressure is especially important in governing the movement of water in the nephrons of the kidneys to ensure proper filtering of the blood to form urine As hydrostatic pressure in the kidneys increases the amount of water leaving the capillaries also increases and more urine filtrate is formed If hydrostatic pressure in the kidneys drops too low as can happen in dehydration the functions of the kidneys will be See Answer
