The Crazy Circulatory System of Perch
Two chambered heart (sinus venous, bulbous arteriosus, atrium and ventricle)- keeps the blood pumping and flowing through the single loop system. The atrium is the upper chamber of the heart and circulates the blood to the ventricle.
Gills- oxygenates the blood
Arteries(efferent branchial arteries,afferent branchial arteries, ventral aorta, intestinal artery, gonadal artery,pneumatic artery,dorsal aorta, and celiac artery)
- Carries and circulates oxygenated blood through out the body and organs from the heart
Veins(hepatic portal vein, intestinal vein, left posterior cardinal vein, and right cardinal vein)
- Carries the deoxygenated blood to the heart
Capillaries - The capillaries send the oxygenated blood from the arteries to the tissue of the
fish and send the deoxygenated blood from the fish's tissue into the veins.
