COMPARATIVE ANATOMY: ANIMAL BODY SYSTEMS: CIRCULATORY SYSTEM AISD

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.

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”
