Term | Definition |
---|---|
acidosis | a decrease in the pH of the blood due to an accumulation of acids; may result from respiratory or metabolic disturbances |
alkalosis | an increase in the pH of the blood due to a loss of acid; may result from respiratory or metabolic disturbances |
anion | ion with negative charge |
buffers | mechanisms employed by the body to keep acids and bases in balance |
cation | ion with a positive charge |
dehydration | a fluid deficiency resulting form the loss of more water than sodium |
edema | accumulation of fluid in interstitial spaces |
electrolytes | substances that break up electrically charged particles called ions when dissolved in water |
extracellular fluid | body fluid residing outside of cells |
hypercalcemia | an excessive concentration of calcium in the blood |
hyperkalemia | an excessive concentration of potassium in the blood |
hypernatremia | an excessive concentration of sodium in the blood |
hypocalcemia | abnormally low blood calcium |
hypokalemia | abnormally low blood potassium |
hyponatremia | abnormally low blood sodium |
