Glomerular Filtration Rate

antidiuretic hormone (ADH) in the distal convoluted tubules. Therefore, resulted into ANP pathway turning off ADH, renin and aldosterone. At T=30 to T=90, there was increase in urine flow rate for drinking group which increased in plasma volume and blood, decreased in aldosterone concentration and plasma vasopressin (Evans, et al., 2009). Additionally, increment in urine flow rate, Atrial natriuretic peptide (ANP) attributed to the increase in the Glomerular filtration rate (GFR) and glomerular permeability; Atrial natriuretic peptide (ANP) had a direct contribution to the increase of radius and the large glomerular pores (Theilig, Wu. 2015). The Glomerular filtration rate (GFR) rate increased as the surface area of the capillaries increased.…show more content…
Based on the result, my hypothesis was partially supported because coke group had the lowest urine flow rate than other groups (Figure 2). Coke group consist of high H3PO which can also be seen in the urine flow rate and had the high amount of ammonia excretion (Vries, E, et al., 1986). But my hypothesis didn’t support as coke group had the highest urine specific density as compared to the Water and Gatorade groups (Figure 3). Coke group had a about the same pH level as the Gatorade group and lower pH than water group. This result implies that because coke is hyperosmotic to plasma, it has phosphoric acid, caffeine and more glucose than water and Gatorade (Figure 4). When we ingested the glucose, there wasn’t much of water being absorbed and glucose was transported to cells and it had reduction in plasma osmolarity (Evans, et al., 2009). Since the osmolarity of the blood was being lowered, ADH and aldosterone continues to regulate the blood osmolarity, blood volume, and blood pressure. Gatorade is sodium concentrated and brain monitors the anti-diuretic hormone (ADH) levels and there was a high level of sodium in the Gatorade group as compared to other Drinking groups. Therefore, Gatorade group had increased antidiuretic hormone (ADH), it resulted to increase in osmolarity and high blood pressure and blood volume. The salt load…show more content…
Water group had rapid and significant result on urine flow rate (Vries, E, et al., 1986) During the process of antidiuretic hormone (ADH) being inactivated and Atrial natriuretic peptide (ANP) being activated, caused increase in urine flow rate had increased as the body was able to reabsorb the amount of fluid it required and while the fluid was secreted, was activated and was inactivated (Theilig, Wu. 2015). At T=120, water group still had the highest urine flow rate, even though urine flow rate decreased for all the groups. At T=120 coke group had a lower urine flow rate than water group but higher than Gatorade group because coke had a high level of sugar, and it was being used to form energy in the form of glycolysis and water for the dehydrated body (Anderson, LJ, et al., 1998). Through T=30 to T=120, non-drinking group had the lowest urine flow rate, ADH was secreted by the posterior pituitary gland to reabsorb and retain
