Hemolymph structure
WebHemocyanins are copper-containing, respiratory proteins that occur in the hemolymph of many arthropod species. Here we report for the first time the presence of hemocyanins in the diplopod Myriapoda, demonstrating that these proteins are more widespread among the Arthropoda than previously thought. The hemocyanin ofSpirostreptus sp. (Diplopoda: … WebHemolymph has a neutral or slightly acidic medium, which is maintained by the anions of certain acids. From 75 to 90% of the total solution is water, and the rest of the volume is formed elements and other solutes. The ion composition of the hemolymph is also varied. It contains cations of sodium, potassium, magnesium and calcium.

Four types exist: one-, two-, three-, and four-chambered hearts (fig. 1). Actually, each type of heart is specially designed to function with only one of the four types of circulatory systems.
Hemolymph, or haemolymph, is a fluid, analogous to the blood in vertebrates, that circulates in the interior of the arthropod (invertebrate) body, remaining in direct contact with the animal's tissues. It is composed of a fluid plasma in which hemolymph cells called hemocytes are suspended. In … Meer weergeven In the grasshopper, the closed portion of the system consists of tubular hearts and an aorta running along the dorsal side of the insect.

Such nucleating agents have been found in the hemolymph of insects of several orders, i.e., Coleoptera (beetles), Diptera (flies), and Hymenoptera. Inorganic Meer weergeven In some species, hemolymph has other uses than just being a blood analogue.
