Q.134) In frog, the Renal portal system is a special venous connection that acts to link:
A) Kidney and lower part of body
B) Liver and intestine
C) Liver and kidney
D) Kidney and intestine
In frogs, the renal portal system is a unique system that collects blood from the hindlimbs and other posterior parts of the body and directs it into the kidneys before returning it to the heart. The system primarily connects the liver and kidney, allowing partial filtration of blood in the kidneys before entering circulation again.
Hence, the correct answer is option A) Kidney and lower part of body.
