Objectives

Students will be learning about the external and internal anatomy of a perch. Students will focus on the organs, structures, and functions of the circulatory system.

Adaptations

A perch's scales protect it from the environment. Its gills allow it to breathe in the water where it lives. Its multiple fins and its tail allow for it to slide through the water. Perches have specialized teeth called palatines that allow it to eat other fish and insect larvae. Perches also have a bony flap called the operculum that protects their gills.

Circulatory System Of a Perch

The heart of a perch has one atrium. Blood is pumped from the heart towards the gills where it is pumped full of oxygen. Then the oxygen-rich blood is distributed in the body.

The circulatory system of a perch works closely with its respiratory system because blood needs oxygen which comes from the gills
