Question:
Response:
Fill in the correct number from the above nephron scheme next to each separate text description. If multiple numbers need to be entered for a description, you should enter them combined in the right order with no separations between the numbers.
1 Site of pressure filtration where small molecules leave the blood
10 Carries blood from the renal artery to the glomerulus and into the peritubular capillary network
13 Outer medulla
12 Cortex
15 Renal papilla
14 Inner medulla
Above you see a kidney slide with an immunohistochemical stain (selective blackish color). Such a selective stain gives you specific information about particular tissues and strucure types and their location in the kidney. What specific nephron segment is specifically stained in this histological slide? Think what type of tubuli you expect most at this level in the kidney, you can eliminate some possibilities by looking at the tubule profiles... Hint : Do you see the ratio between the tubuli profiles ? Also, think about the different length of the tubuli segments...
