The Circulatory System of a Perch

The Circulatory System of a Perch consists of mainly the heart, the gills, and the veins. The gills are used to breathe in the oxygen through the water. The heart is used to pump the blood that has been oxidized by the inhaled oxygen. And finally, the veins are used to transport the oxidized blood to all the bodily cells to provide them with the oxygen needed for life.

This project is going to end with pictures of our mutilated fish.
