	Fine Structure of the Caenorhabditis elegans Secretory-Excretory System
		(3) The pore cell encloses the terminal one-third of the duct and underlies the excretory pore at the ventral surface of the animal.
		This portion of the excretory gland is bound to the duct cell (D) and excretory cell (E) by a complex tight junction (tj).
		The secretory-excretory junction, centered at the anterior edge of the excretory cell body, is the point at which the gland and the excretory cell converge with the duct cell at the origin of the excretory duct.

		The excretory canal cell functions in part as a kidney, excreting saline fluid via the duct and pore in order to maintain the animal's salt balance (osmoregulation) and probably to remove metabolites (Nelson and Riddle, 1984; Buechner et al., 1999).
		It should be noted that in the embryo, G1 cell functions as the excretory pore cell (=excretory socket cell), and in L1 larva, G2 becomes the pore cell.
		The excretory duct is located anteriorly to the excretory cell and opens to outside via the excretory pore at the ventral side of the animal.

		The kidney and its associated ducts are the excretory system of the mammal, and, as already noted, most of the nitrogenous waste arising in the mammalian body is excreted as urea.
		The excretory system is unique in its nephrons, which filter the blood in the glomeruli and remove a variety of wastes from the body through selective secretion and reabsorption.
		The excretory organ in the branchiopods is the maxillary, or shell, gland, so called because loops of the excretory duct can be seen in the wall of the carapace.

		The excretory cell is a large ectodermal cell located beneath the posterior pharyngeal bulb, and it extends tube-like canals dorsally on both sides during embryogenesis (Hedgecock et al., 1987).
		The remaining growth occurs along the length of the canal, as the hypodermal cells, to which the canal is connected by gap junctions, expand.
		GFP fluorescence was observed in the excretory canal (Figure 4A), consistent with the role this protein plays in the formation of canal structure.

	The Excretory System (Site not responding. Last check: 2007-10-22)
		The Excretory System is "responsible for eliminating toxins and waste from the body." It does this by regulating the "chemical composition of body fluids by removing metabolic wastes and retaining the proper amounts of water, salts, and nutrients." (2) Assisting in this effort are the Lymphatic System and the adrenal and thyroid glands [Endocrine System].
		The lungs (Respiratory System) are an important part of the Excretory System because they excrete carbon dioxide.
