There are three processes involved in the formation of urine namely filtration, tubular reabsorption, and tubular secretion. The filtration process occurs in the Bowman’s capsule where the blood is filtered through the ball of capillaries called as the glomerulus. The tubular reabsorption occurs in the proximal and distal convoluted tubules where the essential substance like amino acids, vitamins, and glucose are reabsorbed. The tubular secretion involves the secretion of drugs and toxins in the lumen for its removal.

Which one of the following statements is false?a. Blood pressure in the glomerular capillaries is greater than the osmotic pressure exerted by proteins in the plasma within the glomerular capillaries.b. If the osmotic pressure exerted by solutes in the peritubular capillaries is greater than the blood pressure in those capillaries, then water will be reabsorbed.c. Endothelial cells in glomerular capillaries are highly permeable, facilitating filtration of fluid into Bowman’s capsule.d. Constriction of the afferent arteriole is likely to reduce the volume of filtrate appearing in Bowman’s capsule.e. The efferent arteriole carries blood from the glomerular capillaries directly to the renal vein.0.5 pointsQuestion 2Your doctor calls with the results of your urinalysis and tells you that they found proteinuria, the presence of abnormal amounts of protein in your urine sample.

Water moves out of the filtrate of the descending limb of the nephronloop becausea. there is a high concentration of solutes in the surrounding fluid.b. the cells of the descending limb are permeable to ions.c. the difference in the diameter of the arterioles creates a pressuregradient.d. there is a high concentration of solutes in the descending limb.

Which of the following is true about the filtrate as it travels through the tubule? A. as the permeability to water of the collecting duct increases, the osmolarity of the filtrate increases B. it decreases in osmolarity as it travels through the proximal tubule C. the increasing concentration of the medullary interstitium results in more water being reabsorbed in the ascending limb D. the volume of the filtrate decreases the most in the distal convoluted tubule and collecting duct
