How Does Caffeine Affect The Body
You most likely have consumed soda, green tea and possibly coffee in your lifetime before. But have you ever stopped to wonder how the caffeine in the drink affects your blood pressure?Our experiment is over how certain amounts of caffeine affects our bodies. We thought it would be a great idea to make this experiment more well rounded, we used common drink most people people consume these days. We were interested in this subject because most Americans love caffeinated or sugary drinks, because so we drank some drinks that have caffeine in them and tested our blood pressure and heart rate to see what would happen. As I suspected, it raised both and by a good amount. Some variables in the experiment were the different amount of caffeine as

    By a different mechanism (that doesn't involve beta-1 adrenoceptors), caffeine also increases the amount of cAMP in the sinoatrial node. Then cAMP levels increase and this increases the electrical activity of the sinoatrial node, making it depolarize and 'beat' faster. Caffeine has additional effects on the heart. Like adrenaline and noradrenaline, it can affect the main pumping chambers (ventricles) leading to an increase in the rate of contraction and relaxation of each heart beat. This means that as well as beating faster, the heart's individual beats are associated with an increased volume of blood ejected into the circulation per unit time. This is called increasing cardiac output. Two or three cups of strong coffee or tea contain enough caffeine (and a similar acting compound called theobromine) to cause an increase in human heart rate of 5-20 beats/min.…

    Caffeine is a stimulant. It will work by causing the nervous system to work faster. Also, it will cause the blood vessels to constrict. (LaFave, 2003) These effects will work together to increase an animals heart rate. Under normal circumstances, the heart rate will increase as more caffeine is added. At some point the high concentration of caffeine will cause the heart to stop functioning.…

    The experiment showed that age and body weight contribute greatly to the blood pressure of an individual. Persons that were obese and in an older age demographic had greater instances of hypertension. Hypertension occurred earlier in males than in females. Hypertension seemed to be greater influenced by behavior/lifestyle choices than family history.…

    Our hypothesis was that caffeine would increase the heart rate of the daphnia that were exposed to it. As seen on my graph, the control group of daphnia that was not exposed to any levels of caffeine had an average heart rate of 195.9 beats per minute, the group that was exposed to the .5% concentration of caffeine had an average heart rate of 185.5 beats per minute, and the group that was exposed to the 1% concentration of caffeine had an average heart rate of 217.5 beats per minute. As expected, the daphnia that were exposed to the 1% concentration of caffeine had a significant increase in heart rate. Unexpectedly, the daphnia that were exposed to the .5% concentration had a lower average heart rate than that of the control group. This may have occurred because the only two daphnia that died during this…

    The healthiness of coffee has been a topic of debate for many years. Being one of the most common drinks in the world, people have argued all sorts of positions in regards to its benefits or detriments to their health. Kris Gunnars’ article, “13 Health Benefits of Coffee, Based on Science” argues that coffee is indeed healthy, and provides thirteen reasons why. Jim Dillan’s article, “7 Negative Effects of Coffee & The Healthy Drink You Should Replace it With,” argues the opposite, claiming that coffee is overall harmful to the human body. Although coffee has both positive and negative side effects, Gunners’ article is much more informative, due to its abundance of citations, its large number of well-developed points, and the fact that the article remains consistent with its title.…

    For this experiment I believe that the cardiac arrhythmia will increase as the concentration of the caffeine increases. I also believe that the three the reading of the systolic pressure with distilled water will increase as distilled water contains less oxygen in comparison to normal water. This means the heart will have to beast faster in order to obtain oxygen for cells.…

    Caffeine, the stimulant in coffee, has been called “the most widely used psychoactive substance on Earth .” Synder, Daly and Bruns have recently proposed that caffeine affects behavior by countering the activity in the human brain of a naturally occurring chemical called adenosine. Adenosine normally depresses neuron firing in many areas of the brain. It apparently does this by inhibiting the release of neurotransmitters, chemicals that carry nerve impulses from one neuron to the next. Like many other agents that affect neuron firing, adenosine must first bind to specific receptors on neuronal membranes.…

    A drug is a substance which has a discernible physiological effect when taken into the body. These chemicals change the functions of the central nervous system (CNS), providing temporary relief from mental, physical and social problems. Usage of a drug over a period of time often results in dependence and tolerance of the drug. The user experiences physical and psychological withdrawal symptoms when attempts are made to quit the drug. Tolerance refers to the increased ability of the body to tolerate the drug without ill effects. Due to drugs having the capacity to enhance performance, they are often used recreationally and abused. This leads to addiction which can potentially destroy lives. Drugs which alter behavior could be categorized as…

    The individual results of the well-trained female showed varying results in blood pressure. Considering this is a well-trained female college student, exercise or caffeine prior to the lab could explain the above average blood pressure. In the posture portion of the experiment, a drop in blood pressure was expected when the individual rapidly stood up after lying prone however, the BP remained stable. If this measurement was not taken quickly enough or the individual did not stand up fast enough, the baroreceptors would have already adjusted for the decrease in arterial pressure in the upper body thereby stabilizing blood pressure. In the class data for the effect of conditioning on heart rate, it was found that individuals with a higher level of conditioning had a lower heart rate at all exercise levels. Their resting heart rate decreased by 6.7 beats per minute from poor to good fitness and again from good fitness to excellent fitness. Highly trained individuals also remained at a lower heart rate during exercise. Individuals in poor or good condition demonstrated a much higher resting heart rate and reached a higher heart rate during the moderate and heavy exercise. Participants in this experiment that exercised regularly would have a lower heart for many reasons. Athletes tend to have a larger blood volume and, therefore, a greater carrying capacity of oxygen. Their ventricular…
