The Circulatory System The frog heart is the only organ contained within the coelom which has its own protective covering. This is the pericardium (see Heart). There are two upper chambers of the heart, the right atrium and the left atrium.
Dissecting a frog, we will learn about the digetive, respitory, circulatory, and nerve systems. Their functions and the organs needed for these functions. Create a Flow chart listing human digestive systems with that of a frog. If you don't want to perform the procedure of dissection, there are websites available that show everything.
