Anti Diuretic Hormone Lab Report

Since all individuals will begin the experiment in a slightly dehydrated state there will be high levels of Anti diuretic hormone and aldosterone, ANP levels on the other hand will be at a reduced level. We will test four different conditions during the experiment, continued dehydration, consumption of water, coke and Gatorade. All of these conditions will cause a shift in various aspects of homeostasis and will require compensation from the body through the renal system.
The consumption of water based on an individual’s weight will cause a shift in the plasma volume of the individual fifteen to twenty minutes following consumption. At this stage the osmolarity of the individual will drop since the amount of water present in the plasma has increased, this will also lead to an increase in blood pressure of the individual. Due to the shift in osmolarity in the body the osmorecptors in the Hypothalamus of the brain will send a signal to the Posterior Pituitary, this signal will cease the release of ADH and allow any remaining ADH in the body to begin reaching their half-lives. Without the continued influx of ADH to the renal system the amount of aquaporin openings present in …show more content…
Since the body will continue to remain and progress towards a more extreme level of dehydration the body will continue to reabsorb any water that it can to avoid having blood pressure drop drastically. Since water follows Na+ molecules both must be conserved in order to maintain the osmolarity and blood pressure. As a result the urine that is excreted will be very concentrated and due to the volume being extremely low. Urine pH would most likely be slightly more acidic due to the presence of ketones from fat metabolism, but not to the extreme of Coke or
