Answer
Correct option: B.
Earthworm - Closed circulatory system
b
Earthworm has closed circulatory system. The blood circulates in definite walled blood vessels. Renal portal system is characteristic of reptiles. In reptiles, renal portal system brings blood from internal organs to the kidneys because their digestive tract and urinary tract only have cloaca to eliminate wastes. Humans have hepatic portal system that brings all the venous flow from digestive system into the liver. In cockroach, the excretory organs are malpighian tubules not nephridia
