1. COMPARATIVE ANATOMY: ANIMAL BODY SYSTEMS: CIRCULATORY SYSTEM AISD - 2009

2. Circulatory System Function: brings oxygen, nutrients, and hormones to cells, fights infection, removes waste, regulates body temp. The system that transports!!! Invertebrate Organs: simple heart, vessels Vertebrate Organs: ◦ Heart, blood vessels (veins, arteries and capillaries) and blood Where is your blood made? Hint: It’s made in a different system.

3. Animal circulation Circulation systems are the systems used to transport oxygen throughout the body to the cells so they can perform the essential process of cellular respiration. Why does you heart pump blood? BE SPECIFIC… Hint: the answer is not “TO LIVE”

4. Section 29-2 Insect: Open Circulatory System Annelid: Closed Circulatory System Heartlike structures Blood vessels Heartlike structure Small vessels in tissues Blood vessels Hearts Heart Sinuses and organs Figure 29–10 Invertebrate Circulatory Systems Why are closed circulatory systems more efficient than open?

5. Section 33-3 Double-Loop Circulatory System Single-Loop Circulatory System FISHES MOST REPTILES CROCODILIANS, BIRDS, AND MAMMALS Figure 33–11: The Circulatory Systems of Vertebrates Trace the flow of blood through a single loop system? Pg. 860 Trace the flow of blood through a double loop system? Pg. 860
