Pulse rate During the practical while at rest the pulse is at a normal speed as the person is not doing any activity which requires lots of energy. This changes when the person starts to exercise as the line on the graph increases‚ this shows that the pulse rate is increasing because the heart is beating faster to make sure enough oxygen reaches the cells‚ this also causes the breathing to increase as the body has to take in more oxygen to supply the body and remove the carbon dioxide. In the body

“How Pulse Rate is Affected By Lack of Sleep” By Southern Illinois Biology 200A Section 8 Ashley Hintz September 29‚ 2011 Results The purpose of this experiment was to find out if sleep affects your pulse rate. My hypothesis for this experiment was the people with less than six hours of sleep will have a higher pulse rate. I predicted that if sleep effects pulse rate then a person who has less than six hours of sleep will have a higher pulse rate. Both of which are supported in tables

The heart is a vital organ in the human body. Though only the size of the fist‚ it pumps blood to the rest of the body by rhythmic expansion and relaxation. The frequency of this cardiac cycle is measured by the term heart rate. The heart rate is the number of contractions (beats) of the heart in a minute. The heart rate tends to increase with response to a wide variety of conditions like vigorous physical activity or according to our hypothesis‚ music. Music has an arousal effect which is related

My results and the graph indicate that as you add the caffeine to the daphnia‚ the eart rate of the daphnia increases for example the daphnia’s heartbeat is 120 without caffeine‚ however when caffeine is added it is increased to 168. My graph shows a positive correlation and the error bars are also very small which shows that the results have a small range which suggests that my results are accurate and reliable. I think that the experiment was conducted well however there may be some ethical issues

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

Homeostasis of BP and Heart Rate A normal blood pressure can be identified by having a systolic pressure of around 120 and a diastolic pressure of around 80. This value is expressed as "120/80". A normal heart rate is expressed as the amount of times it beats in a minute; a normal adult heart rate is between 60-100 beats per minute (BPM). There is a relation between these two measurements‚ but they are stimulated by several different circumstances. The blood pressure is mainly affected

The Effect of Exercise on Heart Rate The aim of this investigation is to find out how different types of exercise can affect my heart rate. To measure and record my heart rate‚ I am going to undergo an experimental test. I am going to do 3 different types of exercise: walking‚ light jog and lastly hard running. First‚ I will draw out a table to record my results‚ and then I will measure my resting heart rate for one minute. To make the experiment as accurate as possible‚ I will

To define ectopic pacemaker. I nvestigation of human cardiovascular physiology is very interesting‚ but many areas obviously do not lend themselves to experimentation. It would be tantamount to murder to inject a human subject with various drugs to observe their effects on heart activity or to expose

customers’ needs anymore. So‚ our company has designed a brand new promotional gift. It can best suit our clients’ needs and lifestyles. This is – a heart rate watch. First of all‚ if you look at this paper‚ you can see that this watch has a function that has never been designed for before – a heart rate monitor. It enables the users to measure their heart rate while doing exercises. Actually‚ the underlying purpose of this design is to immerse into customers’ daily lives. Let’s imagine that‚ when you

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 in length. Daphnia are members of the order Cladocera‚ and are one of the several small aquatic crustaceans commonly called water fleas because of their saltatory swimming style (although fleas are insects and thus only very distantly related). They
