- The pigment responsible for the yellow color of urine is DLNY True or Fals&? Cloudy, turbid urine always indicates a pathological problem. 2 \ \ 3. The general term for proteins in the urineis __\Jeo A 4 \bimmnyre refers to the specific presence of albumin in the urine. This condition indicates increased permeability of the glomerular capillaries and is associated with many conditions, such as increased blood pressure, exercise, pregnancy, excess protein intake, heavy metal poisoning, bacterial toxins and glomerulonephritis. 5. Yyuy refers to the presence of WBCs in the urine. Itis { associated with inflammation of the urinary tract 6. N TNV Vg refers to the presence of ketone bodies in the urine and is assaciated with starvation and diabetes mellitus. T wioo oI v G is produced as a result of hemoglobin breakdown. In the liver, this compound is secreted into bile. 8. o\Wp Al refers to the presence of bilirubin in the urine and is associated with liver damage or bile duct obstruction. 9. Large amounts of urobilinogen in the urine may indicate ¢ 6 \nOoIS , o1\ ;o | ONSeoe 10. O\ LK refers to the presence of glucose in the urine and is associated with excess carbohydrate intake or diabetes mellitus. 11. e refers to the presence of RBCs in the urine and is associated with irritation of urinary tract organs or infections. 12, 2\ W refers to the presence of hemoglobin in the urine. Itis associated with hemolytic anemias, transfusion reactions or severe burns. 13. ¢ refers to the presence of nitrites in the urine. Nitrites In the urine are usually (but not always) produced by bacteria. \ p \ e 14.

Questions about Glomerular Filtration Rate (GFR) 15. What is GFR? . The rate of urine production per day b. The rate of fluid movement between the glomerulus and Bowman's capsule ¢.The rate of reabsorption from the convoluted tubules d. The rate of secretion of excess ions 16. Which force that affects GFR is normally zero? '5. Bowman's capsule osmotic pressure kb. Bowman's capsule hydrostatic pressure “c. glomerular capillary blood pressure d, plasma colloid osmotic pressure 17. Bowman’s capsule osmotic pressure a/favors filtration b. opposes filtration 18. Bowman'’s capsule hydrostatic pressure W \ a. favors filtration / B opposes filtration 19. Glomerular capillary blood pressure \ \i/ ( fa)favors filtration b: opposes filtration 20.
