The Circulatory System

The perch circulatory consists of the heart, atrium, ventricle, gills, and ventral aorta. It basically works the same as ours. Blood is pumped through the heart and the lungs, and after it is oxygenated it is dispersed through the body and then back to the heart. The heart helps to circulate blood. The atrium and ventricle are part of the heart, also helping to pump blood. The gills help by enabling water to exchange oxygen and make it able for the perch to breathe underwater. The ventral aorta functions as a canal, circulating blood from the heart to the gills and then the rest of the body.
