  1. CHAPTER 42CIRCULATION & GAS EXCHANGE MosammatTaher & Alyssa Weaver

  2. GASTROVASCULAR CAVITY Works for both digestion and carrying nutrients throughout the body Jelly Fish Hydra

  3. OPEN & CLOSED CIRCULATORY SYSTEMS OPEN: Circulatory fluid covers organs directly and has same circulatory fluid CLOSED: Blood is only in the vessels and is different from the interstitial fluid

  4. Mammalian Circulation The Circulatory System THE HEART Blood from right ventricle goes to the lungs for oxygen. Oxygenated blood goes to the left ventricle to pump blood throughout the body.
