hemolymph [′hē·mə‚limf]
(invertebrate zoology) The circulating fluid of the open circulatory systems of many invertebrates. Hemolymph a fluid that circulates in the vessels and intercellular spaces of many invertebrates with an open system of blood circulation, such as arthropods and mollusks. Hemolymph performs the same functions as blood and lymph in animals with a closed circulatory system (some worms, vertebrates). It transports oxygen and carbon dioxide, nutrients, and secretory products. It is rich in organic substances, including proteins, and frequently contains the respiratory pigments hemocyanin and hemoglobin. Hemolymph also contains cellular elements of various structure and function (phagocytes, excretory cells, and, in some cases, erythrocytes). Want to thank TFD for its existence?
