Heart Dissection & Models
Prof. W. Kleinelp
OBJECTIVES
1. To understand he structure of the heart
2. To identify the numerous chambers, valves and structures of
chambers of the heart
3. To trace a drop of blood though the heart identifying all
locales and regions
4. To correspond the heart model to the dissection
