Perch Fish

Circulatory System


By doing basic procedure on the Perch fish, I've observed carefully, the organ systems of the fish, mainly The Circulatory System.

Circulatory system

Organs Involved: Mainly the Heart

The circulatory system of the perch is a low pressure type of system in which the heart is a single pump and there is a single circuit of blood flow. Venous (deoxygenated) blood from the body is pumped through the heart forward to the gills. From the gills, where it is oxygenated, the blood goes directly to the body. Thus the blood makes a single circuit during which it is pumped, oxygenated, and distributed to the body, before it returns to the heart. In this pattern of circulation the heart pumps only deoxygenated blood.

Other Systems Associated with the Circulatory System

The Respiratory System is associated with the Circulatory System.

The Perch use their Gills to breathe and get Oxygen, Gills are filled with Filaments that are long chains of proteins
