Four Drinking Categories Lab Report

The methods used in this lab experiment consisted of having four different drinking categories. These categories were non-drinkers, Coke, Gatorade, and water; the subjects will be chosen randomly to drink one of the drinks and then void 30 minutes after. After voiding, the subjects will have measured their urine temperature, urine volume, calculate specific density, urine pH and urine flow rate. After the calculations are done, the subjects will use the Labstix strips to measure if their urine tests positive or negative for blood, ketones, glucose, and protein. In my hypothesis I will expect water to have the greatest urine volume and flow rate, then all other drinks (Gatorade, Coke, and non-drinkers). Non-drinkers will have the highest specific density out of all other drinks, both Gatorade and Coke will be in between these three categories. Urine pH is expected to be high in water and low in Coke due to the acidity of both drinks.
When it came to urine volume voided for the four drinking categories, there was a huge increase in volume voided when it came to water than the other drinks (Figure 1). Water tends to decrease ADH levels, thus

Coke has huge amounts of glucose which will increase ADH levels until it is filter out of the blood stream by Glomerular filtration sent from the afferent arterioles; which the glomerular filtration will increase in the proximal reabsorption rate, because the glomerular filtration rate is decreased by the stimulant of vasoconstriction from the afferent arteriole (Kobori, 2007). After T=90, Coke tends to decrease and this could be towards the amount of sugar and that must do with the sugar being filtered through the blood (Figure 2). Aldosterone will act at this point and will increase sodium levels and water will begin to be reabsorbed in the collecting duct by aquaporins thus decreasing urine flow
