Explanation / Answer

1)b-proximal convulted tubule

mercury poisoning is by mercuric chloride.it is corrosive sublimate.causes burning pain,vomiting,circulatory collapse.mercurialentis-brownish deposit of mercury on anterior lens capsule.

2)c-polyuria

seen in diabetes,kidney failure,kidney stones,sickle cellanemia,prostate hyperplasia,etc.

3)b-pyuria

.In membranous nephropathy own immunoglobulins(auto antibodies) affects the glomerulus

4)b-lipoid nephrosis

also called as minimal change disease ,a form of glomerulo nephritis that can result in nephrotic syndromeand progress to end stage renal disease.

5)c- arterial hyalinosis

it is thickening of areterioles walls by the deposits that appear as pink hyaline material in staining ,and is a common ageing process.

6)a-calcium phosphate

when calcium phosphate pass through bladder the stones from urine become concentrated,allowing minerals to crystallize and stick together
