Where is a fish heart located? The heart is located a little behind and below the gills. The typical fish heart has four chambers, however unlike mammals, blood moves through all four in sequence. Venous blood enters the sinus venosus (a thin walled sac) then flows into the atrium, followed by the ventricle (a thick walled pump).
How does a fish heart look? Fish have what is often described as a two-chambered heart, consisting of one atrium to receive blood and one ventricle to pump it, in contrast to three chambers (two atria, one ventricle) of amphibian and most reptile hearts and four chambers (two atria, two ventricles) of mammal and bird hearts.
How many hearts do fish have? In fish, the heart pumps blood first to the gills where the gas exchange takes places, and then the blood continues to the rest of the body. This is a fine balance, since the fish’s gills (like the mammal’s lungs) have to be thin walled to facilitate gas exchange ,and thus cannot tolerate high blood pressure.
Why is the heart near the gills? The heart of a fish is a two-chambered heart. It has one Auricle and one ventricle. Blood from all the parts of the body is sent to auricle, auricle pumps that blood to ventricle and ventricle pumps that blood to gills for the purpose of oxygenation.
