Question

what is the difference between the heart of the fish and the heart of bird​

Answer 1

Answer:

Heart of Fish:

1. Fish Circulatory Systems: The atrium collects blood that has returned from the body, while the ventricle pumps the blood to the gills where gas exchange occurs and the blood is re-oxygenated; this is called gill circulation.
2. The blood is pumped from a three-chambered heart with two atria and a single ventricle.

Heart of Bird:

1. Birds have 4-chambered hearts made of the right atrium, right ventricle, left atrium and left ventricle. The division helps for efficient flow of oxygenated and deoxygenated blood.
2. Their hearts are more efficient to meet the energetic demands of flight, having a larger stroke volume compared to humans.

Answer 2

Answer:

Sol: Fish is a lower vertebrate with a two chambered heart exhibiting single mode of circulation. ... Bird is a higher vertebrate with four chambered efficient heart exhibiting double circulation. Left side of the heart is filled with oxygenated blood and right side of the heart is filled by deoxygenated blood
