Answer #1

Answer - c) Filtered - reabsorbed + secreted = excreted

The kidney excretes the filtrate received from nephron. through glomerulus, the electrolytes, water and other minerals, vitamins and carbohydrates can reach the nephron. hence the excreted material are from filtered. now, through various regions of nephron like PCT, henles loop and DCT many ions and water gets reabsorbed and some are got secreted into it. as reabsored substances are removed and secreted substances are added into the filtered filtrate, c is the correct answer.

Normally no glucose is present in the urine. But in patients suffering from "Diabetes Mellitus" urinary glucose levels are high. Which of the following explanations is most correct?: Glucose transporters in the proximal tubule do not work well in the kidney of diabetic patients. Glucose transporters in the proximal tubule are saturated and therefore not all of the filtered glucose is reabsorbed. Glucose is secreted in the collecting duct. Glucose is secreted in the collecting duct in the presence of...

Which of the following statements about blood acid/base balance is true? Select one: a. Carbonic anhydrase is a membrane protein that transports bicarbonate ion from the filtrate into the tubular epithelium b. The phosphate buffer system is the primary extracellular buffer c. Urinary excretion of hydrogen ion bound to phosphate buffers will increase plasma bicarbonate concentration d. Hydrogen ion binds to filtered bicarbonate in the tubular fluid, then both are excreted in the urine.
