Water movement between ICF compartment and ECF compartment is primarily a function of what? Osmotic Forces In addition to osmosis, what force is involved in the movement of water between the plasma and interstitial fluid spaces? Hydrostatic pressure At the arterial end of capillaries, why does fluid move from the intravascular space into the interstitial space? Capillary hydrostatic pressure is higher than the capillary oncotic pressure Low plasma albumin causes edema as a resu...

minimum urine output for adult 0.5mL/kg/hr ADH (antidiuretic hormone) - water retainer - vasoconstrictor (also called Vasopressin) - produced by hypothalamus - store and released from posterior pituitary ADH pathway - hypothalamus senses low blood volumed and increased serum osmolality - signal pituitary to release ADH - ADH causes kidney to retain water - water retention increases blood volume and decreases serum osmolality ANP (atrial natriuretic peptide) -...

example problem using indicator dilution technique, 5 grams is given and then the concentration is measured and it is 1.0 grams %, what is the volume - V= Q/[x] 500ml = 5/1% = 5/.01 find the osmolarity using the sodium concentration of 140 mEq/L, glucose concentration of 70 mg/dl and concentration of BUN of 12 mg/dl - osm = 2[Na+] + [glucose]/18 + [BUN]/2.8 osm = 2(140) + 70/18 + 4.3/2.8 osm = 288.2 mOsm/l inulin and tritiated water (THO) are infused intravenously into an individual. the ...

Increased Plasma Osmolality - Describes the increased solute concentration Decreased Plasma Osmolality - Means a decrease in solute concentration. Primary Level of Prevention - Alters susceptibility by reducing exposure for susceptible persons to prevent them from getting the disease. e.g., immunizations, dental sealants, condoms, skin cancer prevention via education. Secondary Level of Prevention - early detection and screening. e.g., skin cancer screening, DRE, PSA, PAP smears, self bre...
