Heart Rate Experiment Introduction: The heart rate measures the contractions of your heart and is a requirement for life. The heart uses four chambers. The right and left-lower chambers are called ventricles‚ and right and left-upper chambers are called atria. These four chambers complete two cycles that replenish the tissues with oxygen and get oxygen from our lungs. The heart rate is measured in beats/ minute and a “beat” is when the lower chambers are (two ventricles) contract. This

Discussion Heart Rate Our hypothesis stated 1.) The heart rate increases substantially when a person performs a physical activity and 2.) Females have heart rates greater than males’. In this experiment we measured the resting heart rates and exercise heart rates of both the male and females that are in the class. We calculated the results that were taken by each member of each group in the class (6 males and 16 females total). The average resting heart rate for women was 71.8 beats per minute

Literature Review The human heart is a very complicated organ‚ with the main purpose to pump life sustaining blood throughout the human body. It also supplies oxygen and nutrients to all areas and clears harmful waste from the body. The heart is made up of cardiac muscle which beats on its own. According to the article ‘heart ‘which was written by The National Geographic the heart will slow down or speed up depending on how the body is being used. This is done by nerve signals which are being

Is displacement or distance independent of path? How? 4. Give example of a motion in which distance is covered but there is no displacement. 5. Give one example of motion where‚ distance and displacement are same. 6. When moving car returns to the same point what will be the ratio of

fleas) Introduction- In this study I am going to investigate the effect of caffeine on Daphnia (water fleas) heart rate. I shall use daphnia as they would never have been exposed to caffeine before‚ unlike a human‚ who may have already developed a high tolerance to it. Another reason is that Daphnia have a very translucent body; therefore‚ it is relatively easy to see their heart under a microscope‚ which makes it easier to count the number of heartbeats‚ thus‚ making my results more accurate

music affect the heart rate and what different types of music have a greater affect on heart rate? Music most definitely has emotional value. Heart rate can be directly influenced by these emotional changes. Our group decided to test music tempo’s effect on heart rate. This experiment is relevant to one’s health because it is important to understand how to control one’s heart rate. Before we started conducting our experiment‚ we hypothesized that fast tempo music increases heart rates while slower

Triphosphate (ATP)‚ which gives them the energy they need to perform. In this experiment‚ creatine is added to water and its effects on Daphnia is tested. By observing the heart rate‚ one can determine if the creatine increases or decreases heart rate. Heart rate was chosen to be measured because one can then see how creatine affects the heart. If it is unhealthy for the Daphnia‚ it could potentially be unhealthy for humans. “Long-term safety of creatine supplementation has been questioned. This retrospective

Caffeine effect on Daphnia’s heart rate Prepared for: Androniki Kloni By: Maria Mitsi October 6‚ 2013 Abstract Caffeine is a bitter‚ white crystalline xanthine alkaloid and a stimulant drug. Caffeine is found in varying quantities in the seeds‚ leaves‚ and fruit of some plants‚ where it acts as a natural pesticide that paralyzes and kills certain insects feeding on the plants‚ as well as enhancing the reward memory of pollinators. An experiment was held‚ on an aquatic

Factors Affecting Heart Rate‚ Respiratory Rate‚ and Blood Pressure By Ann-Geyn PanganFor Michele MacKenieInvestigative Team:Biology 0993Nejat MuradOctober 14‚ 2014Jenn SakelariouIntroduction In class we studied circulatory system‚ especially the heart that plays a large part in human. We learned and analyzed its part and function in the body. The purpose of this experiment is to compare the readings of how the heart rate‚ respiratory rate and blood pressure respond to increasing levels of physical
