Detailed explanation-1: -Fishes have only two chambers of the heart-the atrium and ventricle.
Detailed explanation-2: -Fish and Insect Hearts Fish hearts have just two chambers, an atrium and a ventricle (Figure 1).
Detailed explanation-3: -The 2-chambered heart is a simple organ that pumps blood for animals with gills and single circulation. Because blood leaves the gills and immediately circulates to the rest of the body, the heart does not require additional chambers beyond the first two.
Detailed explanation-4: -A typical heart has two upper and two lower chambers. The upper chambers-the right and left atria-receive incoming blood. The lower chambers-the right and left ventricles-pump blood out of your heart.
Detailed explanation-5: -Two chambered hearts are the heart which have one atrium and one ventricle to pump the blood. Complete answer: Fish have two chambered hearts, one atrium and one ventricle to pump the blood throughout the body. Atrium and ventricle are defined as true chambers whereas others are considered as accessory chambers.
