Perch Circulatory System
Perch circulatory systems consist of:
1. A heart consisting of an atrium and a ventricle, which helps regulate the flow of oxygenated and deoxygenated blood
2. Gills, which obtain oxygen from water
3. The liver, which blood always travels through
4. The kidney, which balances internal fluids' pressure
Functions of a Perch's Circulatory System
A Perch's circulatory system functions to send deoxygenated blood off to the lungs, and to send oxygenated blood throughout the fish's body. When blood first travels through the gills, the blood obtains oxygen. The oxygenated blood then travels throughout the rest of the Perch's body. The circulatory system of the Perch is closely related with the respiratory system, because without the gills (a vital organ in the respiratory system), a Perch's blood would not be able to receive oxygen. Without oxygen, a Perch could not survive.
