Explain the differences in respect to the organization and the circulatory pattern between the relatively simple two-chambered heart to the more complicated four chambered heart.

Solution Preview

A two chambered heart has 1 atrium and 1 ventricle. A good example of a two-chambered heart is the Squalus (Dogfish) heart. Only deoxygenated blood is pumped from the heart. The blood pressure leaving the heart is only one pressure and is typically low. Blood passes through the heart only once before going on to the rest of the ...

Solution Summary

This solution provides a brief description of the differences in physiology and structure between a four and two chambered heart.
