  1. AISD - 2009 Comparative Anatomy:Animal Body Systems:Circulatory System

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

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