Cruising through Circulatory System
The perch’s circulatory system is a low pressure system in which its heart pumps the blood flow in a single circuit. Deoxygenated blood from the body is pumped through the heart forward to the gills. The oxygenated blood from the gills goes directly in the body in return. This demonstrates the single circuit of the perch’s circulatory system. Parts of a perch’s circulatory system include the gills, the two-chambered heart (divided into one atrium and one ventricle), dorsal aorta, and a number of veins and arteries. The circulatory system works hand in hand with the respiratory system of a perch as the blood needs to be oxygenated properly for the perch’s use. The circulatory system also utilizes the oxygen obtained from the gills when they enter the filaments to circulate the blood throughout the body.
