Document Summary
Explain their functions in regulating water balance: briefly explain the regulation of na+, k+, and ca++ levels in the body, define ph, list and describe the mechanisms that regulate the ph of the body. Fluid compartments of the body: intracellular fluid, extracellular fluid. 27. 2 regulation of body fluid concentration and volume. Fluid balance: water intake = water output: maintained as long as water intake is equal to water loss, similarly, electrolytes and ph balance is maintained through equal gains and losses, all changes happen in the extracellular fluids. Hormones involved in regulating fluid and electrolyte balance: adh. Do not want to produce as much urine. Does affect water conservation too; as you reabsorb sodium, water will follow: natriuretic hormones increase filtration rate getting rid of more water. Metabolism (not enough to keep homeostatic which is why we have to drink fluids: losses: 27. 4 regulation of specific electrolytes in the extracellular fluid.
