The correct option is D All of the above
Tonsils are collections of the lymphoid tissue facing into the aerodigestive tract.
Renal portal system is an arterial portal system in which efferent glomerular arterioles receive blood from the capillaries of the renal glomeruli and carry it to the peritubular capillary plexus surrounding the proximal and distal convoluted tubules.
Gall bladder is pear-shaped, hollow structure located under the liver and on the right side of the abdomen.
All these structures are absent in rats but present in humans.
Thus, the correct answer is (D) 'All of the above'.
