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 addition to hemocytes, the plasma also contains ...
Hemal nodes (haemel nodes in British English), also known as hemolymph nodes (haemolymph nodes) or splenolymph nodes, are lymphoid organs found in various mammals ...
Hemolymph fills all of the interior hemocoel of the body and surrounds all cells. Hemolymph is composed of water, inorganic salts (mostly sodium, chloride, potassium, magnesium, and calcium), and organic compounds (mostly carbohydrates, proteins, and lipids). The primary oxygen transporter molecule is hemocyanin.
Hexamers are characteristic of arthropod hemocyanins. [17] A hemocyanin of the tarantula Eurypelma californicum [3] is made up of 4 hexamers or 24 peptide chains. A hemocyanin from the house centipede Scutigera coleoptrata [18] is made up of 6 hexamers or 36 chains. Horseshoe crabs have an 8-hexamer (i. e. 48-chain) hemocyanin.
A tarantula's blood is not true blood, but rather a liquid called hemolymph (or haemolymph). At least four types of hemocytes, or hemolymph cells, are known. The tarantula's heart is a long, slender tube located along the top of the opisthosoma. The heart is neurogenic as opposed to myogenic, so nerve cells instead of muscle cells initiate and ...
The system consists of branching tubules extending from the alimentary canal that absorbs solutes, water, and wastes from the surrounding hemolymph. The wastes then are released from the organism in the form of solid nitrogenous compounds and calcium oxalate. The system is named after Marcello Malpighi, a seventeenth-century anatomist.
Hematodinium Scientific classification Domain: Eukaryota (unranked): SAR (unranked): Alveolata Phylum: Dinoflagellata Class: Syndiniophyceae Order: Syndiniales Family: Syndiniaceae Genus: Hematodinium Chatton & Poisson, 1930 Species Hematodinium perezi Hematodinium is a genus of dinoflagellates. Species in this genus, such as Hematodinium perezi, the type species, are internal parasites of the ...
Within each of the major veins is a nerve and a trachea, and, since the cavities of the veins are connected with the hemocoel, hemolymph can flow into the wings. [26] As the wing develops, the dorsal and ventral integumental layers become closely apposed over most of their area, forming the wing membrane.
