  2. Hemolymph - Wikipedia

    en.wikipedia.org/wiki/Hemolymph

    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 ...

  3. Haemal node - Wikipedia

    en.wikipedia.org/wiki/Haemal_node

    Hemal nodes (haemel nodes in British English), also known as hemolymph nodes (haemolymph nodes) or splenolymph nodes, are lymphoid organs found in various mammals ...

  4. Tarantula - Wikipedia

    en.wikipedia.org/wiki/Tarantula

    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 ...

  5. Circulatory system - Wikipedia

    en.wikipedia.org/wiki/Circulatory_system

    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. There are free-floating cells, the hemocytes, within the hemolymph.

  6. Hemocyanin - Wikipedia

    en.wikipedia.org/wiki/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.

  7. Insect morphology - Wikipedia

    en.wikipedia.org/wiki/Insect_morphology

    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.

  8. Malpighian tubule system - Wikipedia

    en.wikipedia.org/wiki/Malpighian_tubule_system

    Malpighian tubules in most insects also contain accessory musculature associated with the tubules which may function to mix the contents of the tubules or expose the tubules to more hemolymph. The insect orders, Dermaptera and Thysanoptera do not possess these muscles and Collembola and Hemiptera:Aphididae completely lack a Malpighian tubule ...

  9. Blood - Wikipedia

    en.wikipedia.org/wiki/Blood

    Hemolymph may function to carry oxygen, although hemoglobin is not necessarily used. Crustaceans and mollusks use hemocyanin instead of hemoglobin. [ 55 ] In most insects, their hemolymph does not contain oxygen-carrying molecules because their bodies are small enough for their tracheal system to suffice for supplying oxygen.
