Type of circulatory systems Drag and drop each characteristic or example to the correct type of circulatory system: Open Circulatory System - Makes large size possible - Blood and interstitial fluid are combined - Single circulation may be present - Blood stays in vessels - Vessels are open-ended - Blood is directed to every cell in the body - Blood flow to certain regions can be regulated Closed Circulatory System - Makes large size possible - Blood and interstitial fluid are separated - Double circulation may be present - Blood stays in vessels - Blood is directed to every cell in the body - Blood flow to certain regions can be regulated - Hemolymph pumped through vessels Examples: Open Circulatory System - Arthropods - Most mollusks Closed Circulatory System - Frogs - Earthworms - Humans - Octopus

Vertebrates' Circulatory System In all vertebrates (and a few invertebrates), they have a closed circulatory system. In a closed circulatory system, blood is contained inside blood vessels and circulates unidirectionally from the heart around the systemic circulatory route, then returns to the heart again. Invertebrates have an open circulatory system. In an open circulatory system, the blood is not enclosed in the blood vessels but is pumped into a cavity called hemocoel and is called hemolymph because the blood mixes with the interstitial fluid.
Dr. Anas S.
Invertebrates have either open or closed circulatory systems. Functionally, these systems increase the surface area for nutrient, gas, and waste exchanges in large organisms. In open systems (e.g., arthropods and molluscs), hemolymph bathes tissues and organs directly. In closed systems (e.g., annelids), blood is confined to vessels. True or False True False
