The purpose of this lab report is to examine the effect of caffeine on heart rate in a controlled experimental setting. Caffeine is a stimulant that is commonly found in drinks such as coffee, tea, and soda, and is also available in supplement form. It is known to have various effects on the body, including increasing heart rate.
To conduct the experiment, a group of participants was recruited and randomly divided into two groups: a control group and an experimental group. The control group was given a placebo, while the experimental group was given caffeine in the form of a capsule. Both groups were asked to rest for 30 minutes before their heart rates were measured using a pulse oximeter.
The results of the experiment showed that caffeine significantly increased heart rate in the experimental group compared to the control group. On average, the heart rate of the experimental group increased by 10 beats per minute (bpm) after consuming caffeine, while the heart rate of the control group remained unchanged.
There are several possible explanations for these findings. Caffeine is a stimulant that activates the sympathetic nervous system, which is responsible for the "fight or flight" response. This activation can lead to increased heart rate as the body prepares for action. Additionally, caffeine may stimulate the release of adrenaline, which can also contribute to an increase in heart rate.
It is worth noting that the magnitude of the effect of caffeine on heart rate may vary among individuals. Factors such as age, sex, weight, and overall health can all influence the body's response to caffeine. Some people may be more sensitive to caffeine and may experience a greater increase in heart rate than others.
In conclusion, this lab report has demonstrated that caffeine has a significant effect on heart rate in a controlled experimental setting. These findings suggest that caffeine consumption may be a potential risk factor for individuals with certain cardiovascular conditions, and caution should be exercised when consuming caffeine. However, more research is needed to fully understand the long-term effects of caffeine on heart health.
Caffeine Lab Report
The bigger the blood vessel radius, the more blood flow or fluid flow. This was repeated for beakers B and C. In modern schools of thought, caffeine has been found to be a lightly addictive, moderate to severe stimulant that affects neurological function in various ways, though scientists disagree Rathe Caffeine Analysis 791 Words 4 Pages The style and tone of the writer determine whether anybody chooses to read the piece, and if they do, if the readers feel offended or interested or bored. Therefore, heart rate increases. This blocks an enzyme called phosphodiesterase from working with another enzyme cyclic AMP to keep the heart at its normal rate. Individuals have been replacing protein bars and other athletic beverages for real food McCarthy.
Effects of Caffeine & Nicotine on Heart Rate lab report
Predominantly, people perceive caffeine as something that increases the risk of irregular heartbeat, otherwise known as arrhythmia. It can thus stimulate human respiration and increase the metabolic rate Haggins et al, 1915. If I were to do this lab again, allow the chemicals to set in for longer amounts of time to make sure the chemical has taken full effect. Beyond the specification and for your own interest, in humans, caffeine binds to receptors within the heart. After the completion of the process caffeine forces part of the neurons in the brain to lighten up, which later on causes the body to release the hormone adrenaline. If not, it might be wise to use diagrams found on line to help your audience visualize Daphnia anatomy. Read more: Once consumed, caffeine enters your blood from the stomach and small intestine and begins to stimulate your central nervous system.
Effect of Caffeine on Daphnia Heart Rate
After this, data collection is fairly quick- you could gather a reasonable amount of data in three 30-minute sessions or one 90-minute microscope marathon and be done. In summary, individuals who consume caffeine regularly or habitually have a lower increase in blood pressure as compared to non-habitual caffeine consumers. Energy drinks and soda are some of the most widely marketed products in the world, even though they contain the highest concentration of caffeine outside of pure caffeine supplements. Energy Drinks are known to give you energy, but part of the agreement that comes with consuming these types of drinks is being ready for the consequence. Through research before the lab, and obtaining an abundance of data from other class groups, caffeine, nicotine, and aspirin will consistently increase heart rate in Daphnia and carry Lab Report Daphnia Ectothermic animals are animals whose body temperature is affected by their surroundings.

Reading and following the safety precautions of all materials used in a project is the sole responsibility of each individual. On the other hand, coffee has 8 ounces. For example, during the first trial, the heart rate went from 20 H. The standard deviation can be displayed on the graph using error bars. Caffeine is the most widely used psychoactive chemical in the world. The results will show that there is a limit to how much alcohol and caffeine the Daphnia can withstand before needing the use a control, crashing, or even dying. What are the goals? However, despite some errors, there is sufficient data from multiple groups to say that nicotine, caffeine, and aspirin increase heart rate, while alcohol and sleep aid decrease heart rate.

Using an organism for the assay is the best choice because there are many variables that can be used to identify stress on the subject because of a specific input. Surprisingly, additional caffeine is not stored in the body. The liver processes it and it exits through urine. Our observed results and our predicted results were the same because the combination of caffeine and nicotine had a stronger effect than caffeine and nicotine alone. The Effects of Caffeine on Heart Rate Over a 2-Hour Period in Four Female Subjects SuperLab V: Molecular and Physiology Dr. From these plants it is processed into its pure form and then put into other things such as soda, energy drinks, tea, and pills.
