42
Location of Kidney
It is located on either side of the backbone and protected by the last two ribs.
43
Location of uriniferous tubule
Uriniferous tubule begins in the cortex; the tubule dips down to the medulla, then return to the cortex before draining into the collecting duct.
44
Malpighian capsule
It comprises of Bowman's capsule and glomerulus and is located in the kidney tubule.
45
Loop of Henle
It runs in the medulla to turn back and to re-enter the cortex to continue into the next convoluted region of the tubule.
46
