Open circulatory system

Simplified schematic diagram of an open circulatory system, showing a tubular or central heart-like pump connected to several short broad vessels that do not form a closed loop but instead open into wide irregular body sinuses or a large surrounding body cavity filled with hemolymph. Fluid pathways are emphasized against pale tissue spaces in a clean clipart-style biological layout.
