Which of the following statements is/are true?
The proximal convoluted tube has cuboidal cells
The descending limb of henle has cuboidal cells
The ureter has transitional cells
The bladder has transitional cells
The distal convoluted tubule has simple squamous cells
The descending limb of Henle is impermeable to water but highly permeable to sodum and chloride ions. The ascending limb of Henle is highly permeable to water, reducing 60L to 36.

The lumen of the proximal convoluted tube is always cloudy because it is rich in salts, sugar, and protein. The brush border is on the basal side of the cell.
Diabetic nephropathy is an abnormal proliferation due to growth factors. These growth factors are released by what?
Podocytes
Mesangial cells
cells of the macula densa
juxtaglomerular cells
intercalated cells
Which of the following cell types are correctly matched to function?
Podocyte- filtration barrier cell
mesangial cell- eat old cells and proteins which may clog the small blood vessels
cells of macula densa- smooth muscle cells which secrete renin
intercalated cells- cells that repopulate the filtration barrier cells
juxtaglomerular cell- has the brush border for uptake of sodium, chloride, and glucose
A type intercalated cells secrete H+. B type intercalated cells resorb H+ and secrete bicarbonate
