Oxygenated blood never goes to the heart in 1) fishes 2)reptiles 3)birds 4)mammals
Dear Student,
The correct answer to your question is option A, fishes. Blood flows only once through the heart of fishes. The deoxygenated blood from different parts of the body of the fish comes to the heart. The heart then pumps the blood to the gills for oxygenation from where the oxygenated blood after the gaseous exchange is circulated throughout the body. Hence oxygenated blood never goes to their heart in fishes.
Regards
