The nephridia are part of which organ system
WebThe excretory system of earthworms (annelids) has slightly more evolved excretory structures called nephridia. A pair of nephridia is present on each segment of the Earthworm. They are similar to flame cells in that they have a tubule with cilia. In Cockroaches, malpighian tubules perform excretion. WebA nephridium is supplied with haemocoelomic fluid. The nephridia will remove the nitrogenous wastes of haemocoelomic fluid. It absorbs, morevammonia, small quantity of …

WebAnnelids possess a well-developed complete digestive system with specialized organs: mouth, muscular pharynx, esophagus, and crop. A cross-sectional view of a body segment of an earthworm is shown in Figure 15.29; each segment is limited by a membrane that divides the body cavity into compartments. WebA central nervous system consists of a mass of nerve cells, called a ganglion, (in more complex organisms, the ganglion evolves into a brain) in the anterior part of the body, and a nerve cord extending from the brain toward the posterior end of the body (Fig. 3.38). Sensory cells in the head detect changes in the environment.

WebKidneys: The Main Osmoregulatory Organ. The kidneys, in mammals, are a pair of bean-shaped structures that are located just below and posterior to the liver in the peritoneal cavity. The adrenal glands sit on top of each kidney and are also called the suprarenal glands. Kidneys filter blood and purify it. WebThe nervous system consists of the ventral nerve cord, which travels the length of the worm on the ventral side, and a series of ganglia, which are masses of tissue containing many nerve cells. The nerve collar surrounds the pharynx esophagus and consists of ganglia above and below the pharynx.
WebThe neurons are the basic functional unit of the nervous system. They generate electrical signals called conducted nerve impulses or action potentials that allow the neurons to convey information very rapidly across long distances. The glia mainly act to support neuronal function.
WebNephridia are homologous to nephrons or uriniferous tubules found in the kidney of humans. Nephridiopores are present in ventral region.
