- Significance of proteins in urine and the various methods for measurement of urinary total protein.arrow_forwardWhich glomerular arteriole is larger, and why? the efferent, because it increases hydrostatic pressure in the glomerulus the efferent, because it increases colloid oncotic pressure in the glomerulus the afferent, because it increases hydrostatic pressure in the glomerulus the afferent, because it increases colloid oncotic pressure in the glomerulusarrow_forwardGiven: Inulin is freely filtered in the glomerulus and not secreted nor reabsorbed in any appreciable amount at the nephron. If the concentration of inulin in the urine is 20 mg/mL, the concentration in blood plasma is 0.2 mg/mL plasma, and the rate of urine flow is 1 mL/min. a. What is GFR for this person? (Answer part a)arrow_forward
- The presence of either protein or glucose in a urinalysis is abnormal but they end up in the urine for different reasons. For each of these molecules, briefly describe where in the urine production process (i.e., glomerular filtration, tubular reabsorption or tubular secretion) the problem occurs, and why it might happen. please helparrow_forwardGlomerular colloid osmotic pressure is greater in the afferent end than in the efferent end of the glomerular capillary regardless of the change in filtration fraction. True or false and why.arrow_forwardThe normal glomerular filtration rate in the following results is: 1) 2 ml/min, 2) 125 ml/min 3) 800 ml/min 4) 1,200 ml/minarrow_forward
