Hemolymph, or haemolymph, is a fluid, analogous to the blood in vertebrates, that circulates in the interior of the arthropod body remaining in direct contact with the animal's tissuesit is composed of a fluid plasma in which hemolymph cells called hemocytes are suspended in addition to hemocytes, the plasma also contains many chemicals.
