Caffeine in Coca-Cola Essay

DesignQuestion Does the caffein in Coca-Cola make kindred hug? Hypothesis The fall of caffein in Coca-Cola leave ca spend to the adrenal glands, kink up on the cash in ones chips of the kidneys, to pocket much adrena railway line which get out in turn ca engross an add-on in rent force per unit area. As the come up of Coca-Cola decreases, so will the difference amid sign tide rip pressing and wrinkle impel later the expending of the caffeine.VariablesVemier LabquestProcedure In recount to test my hypothesis, I decided to use a common caffeinated beverage, Coca-Cola. The gist of caffeine in severally bottle is granted as 48mg/500mL. So, to keep my calculations clean my initial test was with 500mL of the Coca-Cola. I took my billet pres certainly with a Vermier Labquest in advance I consumed either caffeine to withdraw a chair variable. It was a manual livestock shove monitor, so I took my own gillyflower insistency. After placing the cuff on my arm , I squeezed the bulb until the cuff pressure reached clxx mm Hg. Then, I relinquishd the bulb and allow the pressure drop until it was 50 mm Hg and I utilise the release valve on the bulb to completely release the pressure and stopped the entropy allurement.This information was save. Next, I measured the amount of the Coca-Cola employ for the current test into a mensuration cup and then consumed it. I waited 20 minutes after custom to call back my ancestry pressure again. Caffeine has been describe to take affect after a time close of 15-45 minutes. I did an kindred test e very day for quintuplet consecutive days with varying amounts of Coca-Cola consumed. On the first day, I consumed 500mL, 400mL on the secant day, 300mL on the third day, 200mL on the fourth day, and 100mL on the fifth day. I recorded my stock pressure pre-caffeine uptake on each day.* Spike in blood pressure during the third discharge could to a fault be payable to the additional ingestio n of food during the time amid initial blood pressure data collection and post-caffeine consumption data collection. No early(a) rivulets had outside influences on data.Data bear uponThe following is a line graph that represents the systolic pressures of each visitation before and after caffeine consumption in that respect are noniceably great differences between the different tryouts up until the fourth trial when the systolic pressures seem to be most the same. The pressure at trial tierce seems to be an outlier. The following is a line graph that represents the diastolic pressures of each trial before and after caffeine consumptionThe correlation between the diastolic pressures does not go along with my hypothesis in showing that the blood pressure will rise as the caffeine recess rises. The spike at trial tierce is also an outlier here like it was with the systolic pressures. Both of these graphs help to illustrate the channelise in the pressures visually. Conclusi on Although there is any(prenominal) relation between caffeine intake and a rise in blood pressure, my data was not one-hundred percent complete in showing that the to a greater extent caffeine consumed the more of an increase. This would have been shown had the data for trial three been less of an extreme. If the systolic pressure had fallen between 117 and 129 (The systolic pressures for trials 4 and 2) then the data would appear to be much more consistent.The start of this could be directly due to the fact that I was also eating at the time of the trial whereas with the other four tests, the all thing that I was ingesting at that forecast in time was the Coca-Cola. I chose to do this experiment on myself for that very origin I can control my consumption and I am aware of eitherthing consumed that may or may not affect the outcome of the data. If I were to remake this consummate experiment, I would also choose to use myself as the test subject. This keeps my variables t o a stripped-down and ensures uniformity.I would also make sure that at the time of the trials that nothing still the actual harvest-feast, in this case Coca-Cola, was being consumed especially in the time full point between consumption of the test yield and then the second blood pressure reading. I would also shift my equipment. The blood pressure monitor that I used was manual and at times very unreliable. If given the opportunity to redo this, I would purchase a digital blood pressure cuff that would insure that each reading could not be the product of operator error. This could have also been a factor that led to the outlying data for trial three.Time between consumption and taking a blood pressure reading could also be altered. I used twenty minutes due to the fact that it is a short amount of time and I would not have to worry about controlling viable outside factors for a long period of time. However, if I had let the caffeine be in my system for up to 45 minutes, the re may have been more of a noticeable effect to the change in my blood pressure.My hypothesis that the amount of caffeine in Coca-Cola will cause to the adrenal glands, located on the top of the kidneys, to release more adrenaline which will in turn cause an increase in blood pressure. As the amount of Coca-Cola decreases, so will the difference between initial blood pressure and blood pressure after the consumption of the caffeine was somewhat proven to be right. Yes, blood pressure did rise each and every time that I drank the Coca-Cola. However, the latter office of the hypothesis is still unclear. It is unclear due to the data collected in trial three thus the need to redo trial three for an accurate hindrance of my hypothesis.
