Question

In the frog kidney, the cortex and medullary region are

• A. Less distinct
• B. More distinct
• C. Absent
• D. None of the above

Answer 1

Answer: (C)

Absent

There are two kidneys in the frog. The kidneys are nearly identical in position. The kidney is trilobulated and there is no cortex or medullary region represented in the case of frogs. The loop of Henle are absent and the malphigian tubules are scattered in the kidney. The excretory wastes are drained form the coelomic fluid into the coelom by an opening of the kidney called nephrostomes.

Thus, the correct answer is option C.
