Block 3.2 Review Know about influenza virus. Definition of cellular immunity. (T-Cells) Diabetes question – osmotic diuresis. Excess sugar is pissed out and water follows sugar. OSMOTIC DIURESIS : DEFINITION: OSMOTIC DIURESIS- greatly increased urination and dehydration caused when high levels of glucose CANNOT be reabsorbed into the blood (180mg/dL) from the kidney tubules and the osmotic pressure of the glucose in the tubules prevents water reabsorption dehydration. SO… - normally when the kidneys filter blood in the glomeruli- reabsorb useful materials (water, glucose…) -glucose is normally reabsorbed into the body through an active transport process -the body tries to regulate blood glucose between 80-140mg/dL (homeostasis body balanced and happy) -kidneys trying to excrete glucose when 180+ mg/dL (to prevent acidosis) – glucose pulls out fluids with it b’cuz it hypertonic when compared to blood increase in urine (polyuria) CAUSED BY: -if glucose levels are above 180mg/dL, glucose is excreted in the urine and pulls water out with it b’cuz osmotic pressure rises in the kidney and is hypertonic to blood- (osmotic pressure makes water follow glucose in urine). S/S: polyurea(urine, much- pee a lot) diuresis (formation and secretion of large amounts of urine)- glycosuria (glucose in urine, sweet urine – ‘mellitus’) -if this flow rate inside the kidney increases it may cause increased excretion of potassium hypokalemia, which may cause cardiac dysrhythmia’s -usually occurs in diabetes type I Rx: -fluids -insulin as indicated
