is being formed‚ there are three processes that must occur. The first step that occurs is filtration. In this step‚ diffusion occurs under high pressure because blood is moving to the glomerulus of the nephron through the afferent blood vessel. The lumen size of the vessel becomes immediately smaller‚ so when substances in the blood are being filtered out‚ they are pushed through by a high pressure. The kidney at this point is simply trying to maintain a homeostatic control‚ so not everything is filtered

more water reabsorption and water retention. The increased Na in the blood will be filtered into the nephron. The increase makes the sodium transporters not able to reabsorb all of the sodium. Therefore‚ excess sodium and water will remain in the lumen (3). The excess sodium will be excreted into the urine and eliminated from the body. A substance can remain in the blood depending on the amount filtered into the nephron and the amount reabsorbed or secreted by

Cholera‚ aka Asiatic Cholera or epidemic cholera‚ is an infectious disease of the gastrointestinal tract caused by the Vibrio cholerae bacterium. From the family Vibrionaceae‚ the bacterium is characterized as a gram-negative rod. As with other gram-negative rods‚ Vibrio cholerae produces an endotoxin‚ known as cholera toxin. This bacterium is mobile due to the presence of a single polar flagellum and is highly infectious. The Vibrio cholerae bacterium grows in both freshwater and marine habitats
