Circulatory system and chambers in heart of fish
Explain, whether fishes have an open or closed circulatory system? How many chambers are there in heart of the fish and how does blood flow throughout fish body?
Expert
In every vertebrate, including fish the circulatory system is closed, that is, blood flows within the blood vessels.
Fish heart has two consecutive chambers:
a) Thin-walled atrium and
b) Muscular ventricle.
The arterial or the oxygenated blood comes from the gills and gains arteries towards the tissues, and then the venous blood is collected by the veins and reaches atrium of heart passing to ventricle which pumps venous blood in the direction of the gills to become again oxygenated.
