Document Summary
Ace: angiotensin converting enzyme, converts angiotensin 1 into angiotensin 2 (active form) Acidosis: blood ph lower than 7. 35, high co2 and low o2. Adh: antidiuretic hormone, acts in the kidney tubules by reabsorbing water in the kidneys to increase blood volume to reduce serum osmolality. Ascites: fluid that collects in the peritoneal cavity (third spacing) Bun: blood urea nitrogen, amount of nitrogen in your blood that comes from the waste product urea. Urea is made when protein is broken down in your body. Capillary permeability: the capacity of a blood vessel wall to allow for the flow of small molecules and liquid in and out of the vessel. Colloid osmotic pressure: particles like glucose and electrolytes move from vessel to interstitial space and create osmotic pressure, pulling a small amount of liquid into the interstitial space. Edema: interstitial fluid accumulation, readily available for exchange when the underlying issue is resolved extracellular fluid: usually denotes all body fluid outside the cells.
