Does caffeine affect heart rate? Introduction The purpose of this experiment was to see if caffeine had an effect on the heart rate of Daphnia (water fleas) by observing them under the microscope and recording their heart rate over a period of time in concentrations of caffeine. Caffeine, which is a stimulant

Methods and Materials: In order to complete this exercise, two different procedures were conducted; one measured the basal heart rate, and the other measured the drug-induced heart rate. A sample 's basal heart rate can be defined as the “resting” heart rate. This is when no drugs or altering substances are applied. In comparison, the drug-induced heart rate of a sample can be defined as the heart rate after the drug was administered to the surrounding environment. The four drugs tested on the Daphnia specimens were Acetylcholine, Caffeine,
On Your heart is one of the strongest, most controlling organ in your body. The reason I think your heart rate does this is because if you have ever felt a surge of energy when your favorite upbeat song comes on the radio, or if you listen to slow music to relax, the emotions you experience are directly linked to what music does to your heart rate. When you listen to fast paced music your heart rate isn't going to be slow, and same thing if you were to listen to slow, relaxing song your heart rate would be fast.
It has been shown that individuals turn to drugs that elicit a mood or level of arousal consistent with their mode of dealing with stress. Those who deal with stress by confrontation choose drug stimulants. Those who withdrawal from stress chooses opiate drugs. Others who deal with stress through activities related to imagery or fantasy turn to hallucinogens. These differences between behavior and drug preference are thought to be biochemically driven.
When taking amphetamine, users start to get anxious, tense and if they take a heavy dose over a long period of time, they get linked to the mental illness, psychosis. Some drugs, like cannabis, cause the user to become paranoid. Cocaine can cause extreme alertness, impaired judgment, impulsiveness, and compulsively repeated acts. Even though, cocaine is used to enhance the sex drive, the effect that it has on the receptors in the brain reduces the ability to feel pleasure, which eventually causes the dependency on the drug. Another drug that has a powerful effect on the body is Ritalin. Ritalin causes severe headaches, anxiety, paranoia and delusions. These are some of the psychological effects that drugs cause to the human body.
higher percentage caffeine and alcohol placed onto the Daphnia the higher the heart rate. Average Daphnia Magnus Heartbeats per Minute ￼￼ ￼ Conclusion After completing the experiment we found that when we gave the Daphnia caffeine the heartbeat rate did show an increase. However, we also found that alcohol also increased the number of times the heart beat. Even though we performed all of the experiments very carefully, we cannot be certain that the effect we saw was due to the drugs. Perhaps the change in heartbeat rate is caused by
I chose Methamphetamines because of how fast the drug causes users to go downhill. When meth became the drug of choice in Arizona, within a couple months entire neighborhoods were garbage strewn, and the physical effects of the drug became apparent in anyone using. Friends disappeared off the radar, to be seen a month later, unemployed, paranoid, scabbed and thin. I would like to learn more about the history and long-term effects on the body from methamphetamines.
TITLE: Effect of the caffeine on the heart rate OBJECTIVE: To investigate the effect of the caffeine on the heart rate of living organisms. INTRODUCTION: * Daphnia Daphnia are small, planktonic crustaceans, between 0.2 and 5 mm
Introduction Chemicals normally present in the body, blood or interstitial fluid influence the heart rate. “Heart rate, or heart pulse, is the speed of the heartbeat measured by the number of heartbeats per unit of time -typically beats per minute” (Medterms 2012) Substances that increase a heart rate are called stimulants. Substances that decrease the heart rate are called depressants. In this lab the students recorded information on the effects of stimulants and depressants on a Daphne. An example of depressants would be a sleeping pill. For clinical use a lot of consumers take this in order to decrease heart rate and to sleep better. Antianxiety medications affect people who have severe anxiety disorders. “Medications that act as depressants are able to imped this anxiety causing brain activity, thus relieving anxiety symptoms.” (Live strong quote) An example of a stimulant would be adrenaline. Adderall is a great example of a stimulant for clinical use. This drug helps people who are diagnosed with
developed several chemical compounds with aspirations to succeed in the pharmaceutical market. They ended up developing MDMA, but it was not used to treat anxiety until the 1970’s (Cromer, 2013). It did not come under harsh scrutiny by the FDA until the 1980’s due to the growing recreational usage in society (Sessa and Nutt, 2014). This obviously lead to a significant halt in researching this drug, but some clinical trials were able to succeed. However, they had inconclusive results and they still do today. Now that science has come such a long way, scientists are able to better study how the drug works and the long and short-term effects it can have on those taking the drug. Christian, Grey, and Sorg claim that the effects of MDMA set in approximately 20 minutes after ingestion and its effects can last from four to six hours (Christian, Grey, and Sorg, 2015). A psychologist or team of psychologists will administer the drug to the patient and listen to them as they talk about their problems. They will generally not direct the conversation, but allow the patient to direct it and focus on the point of trauma when they feel comfortable and ready. This drug causes an increase in the production of serotonin in the brain, a chemical that is responsible for making people feel content and extremely happy (Cromer, 2013). These feelings of happiness and bliss will then lead the patient to feel more comfortable with their
During the Enlightenment, philosophers were starting to drift away from religion, and many new truths were beginning to be discovered. When these new ideas, or truths, started to make more sense then the certainty of religion, a state of anxiety began to grow within the human mind. As this state of anxiety grew, many anxiety disorders began to sprout and show themselves within humans. These disorders, such as certain phobias, Generalized Anxiety Disorder (GAD), Post-Traumatic Stress Disorder (PTSD), and Obsessive Compulsive Disorder (OCD) began to take over many people’s lives. For many years, doctors have tried using harmful drugs to change the chemicals within the brain, to help relieve anxiety. As truth continues to be discovered, and anxiety continues to rise, therapeutic interventions will be proven to be more efficient in treating anxiety than its counterpart, the dangerous drugs that humans become dependent on.
f. .stimulants can cause enhanced brain activity increase and llertness in energy elevated blood pressure increase heart rate increase respiration and sleep deprivation…. Ultimately these three drugs possess the same long term affect when abused; high potential for physical dependence and addiction.
Those who abuse these medications are still after the calming effects they bring, however it brings them a high instead of peaceful feeling.
However drugs do impact murder rates. When convicting a killer the circumstances in the case such as drug usage must be considered. However it’s uncertain if killing while on the influence of drugs should play a major or minor role when determining a killers sentence and if it’s a drug related case or not,
