LAB 5
ANATOMY OF THE RESPIRATORY, DIGESTIVE, AND URINARY SYSTEMS
Assignments: Due before lab: Quiz: Complete the cardiovascular case studies (page 48). Label diagrams of respiratory, digestive and urinary models (pages 55-65). Due next lab: Lab Exam I – covers labs 1 through 4, the Interactive Physiology CD ROM exercises, and the cardiovascular case studies. Summer Classes: In the summer, Labs 5 & 7 are combined. The quiz covers the Respiratory IP exercises on pages 69-73.
Objectives: Identify anatomical structures on models of the Respiratory, Digestive, Urinary Systems Identify slides of the Respiratory, Digestive, and Urinary Systems and various indicated structures Identify organs of the Respiratory, Digestive, and Urinary Systems in the fetal pig
