Abstract: The purpose is to demonstrate the role of the kidneys in the homeostatic control of extracellular fluid volume, plasma ionic concentrations, and osmolality. Three treatment groups were utilized: a Gatorade group, salt-loaded (access to 0.9 g/l00 ml NaCl) group, and a group who only had water. In this experiment the class was able to observe and analyze the changes in urine production as a means of determining the amount of salt the body gets on a day-to-day basis.
Introduction: The kidneys are important regulators of homeostasis in the body. They regulate ions and pH as well as water. In addition, …show more content…
In adults the GFR should be somewhere between 100 and 130, while in children it should be about 110 (1). Since the GFR is a measure of the kidney 's function it is used to help classify kidney disease. If GFR is too high or too low this would cause problems because 99% of formative urine needs to be reabsorbed. If GFR is too high, needed substances cannot be reabsorbed quickly enough and they would be lost in the urine. If GFR is too low, everything is reabsorbed, including wastes that are normally disposed of. The collecting duct is the key to determining the volume of filtrate that is released and how concentrated the urine …show more content…
The reasoning behind this is that when traveling down the collecting duct the concentration of salt is almost similar both on the inside and in the interstitial fluid. The collecting duct is permeable to water and not salt, so water is drawn out via osmosis, which is determined by Antidiuretic Hormone secretion (3). Whether or not water needs to be conserved determines the amount of ADH that is released. If the hormone ADH is high, then the collecting duct becomes more permeable to water so more water is drawn out which means that less urine volume and it will be more concentrated. If ADH is low then less water is removed and the urine volume is large and more diluted. For the salt group, eating potato chips and drinking the salt solution increased the amount of sodium in the blood, leading to 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
