  2. Organ of Bojanus - Wikipedia

    en.wikipedia.org/wiki/Organ_of_Bojanus

    The organs of Bojanus or Bojanus organs are excretory glands that serve the function of kidneys in some of the molluscs. In other words, these are metanephridia that are found in some molluscs, for example in the bivalves. Some other molluscs have another type of organ for excretion called Keber's organ.

  3. Circulatory system of gastropods - Wikipedia

    en.wikipedia.org/wiki/Circulatory_system_of...

    De-oxygenated haemolymph drains into a large venous sinus within the head and foot, which contains the nephridium, an excretory organ with a function similar to that of the vertebrate kidney. From here it passes into vessels within the gill, or into the capillary network of the pulmonate lung, before returning to the heart.

  4. Nephridium - Wikipedia

    en.wikipedia.org/wiki/Nephridium

    The nephridium (pl.: nephridia) is an invertebrate organ, found in pairs and performing a function similar to the vertebrate kidneys (which originated from the chordate nephridia). Nephridia remove metabolic wastes from an animal's body.

  5. Ctenidium (mollusc) - Wikipedia

    en.wikipedia.org/wiki/Ctenidium_(mollusc)

    Certain molluscs, such as the bivalves, [2] possess paired ctenidia, but others, such as members of the Ampullariidae, [3] bear a single ctenidium. [4] [5] A ctenidium is shaped like a comb or a feather, with a central part from which many filaments or plate-like structures protrude, lined up in a row.

  6. Siphon (mollusc) - Wikipedia

    en.wikipedia.org/wiki/Siphon_(mollusc)

    A siphon is an anatomical structure which is part of the body of aquatic molluscs in three classes: Gastropoda, Bivalvia and Cephalopoda (members of these classes include saltwater and freshwater snails, clams, octopus, squid and relatives). Siphons in molluscs are tube-like structures in which water (or, more rarely, air) flows.

  7. Macula densa - Wikipedia

    en.wikipedia.org/wiki/Macula_densa

    In the kidney, the macula densa is an area of closely packed specialized cells lining the wall of the distal tubule where it touches the glomerulus.Specifically, the macula densa is found in the terminal portion of the distal straight tubule (thick ascending limb of the loop of Henle), after which the distal convoluted tubule begins.

    Volume of blood plasma delivered to the kidney per unit time. PAH clearance is a renal analysis method used to provide an estimate. Approximately 625 ml/min. renal blood flow = (HCT is hematocrit) Volume of blood delivered to the kidney per unit time. In humans, the kidneys together receive roughly 20% of cardiac output, amounting to 1 L/min in ...

  9. Flame cell - Wikipedia

    en.wikipedia.org/wiki/Flame_cell

    Flame cells function like a kidney, removing waste materials. Bundles of flame cells are called protonephridia. [1] The flame cell has a nucleated cell body, with a "cup-shaped" projection, with flagella covering the inner surface of the cup. The beating of these flagella resemble a flame, giving the cell its name.
