Answer:
There are two chambers in fish's heart .
1) Atrium
2) Ventricle
Function : Atrium collects the blood from the body and pump the blood into the second chamber, the ventricle. The ventricle contract and pumped blood to a small stretchable until called a cinus this unit is not consider to be a heart chamber because it doesn't pump the blood. It stretches and squeezes the blood into the aorta which carries the blood to the gills when oxygen is pucked from gills, and thus the blood flows on to the body and distributed the oxygen and finally returns to atrium of the heart to start again.
