Variables Affecting Human Arterial Pressure and Pulse Pressure BIOL 204-506 Remi Ben-Davies Dashaun Lee‚ Amanda Easter‚ and Lynne Baker April 9th‚ 2015 1 Introduction: Purpose: The purpose of this experiment was to determine how different variables may affect arterial pressure and pulse rate. Two subjects were used as models for the tests. The first two tests required the use of sphygmomanometers and stethoscopes to measure the arterial pressure and pulse rate. The last test required sphygmomanometers

Heart Rate‚ Physical Fitness‚ and the Scientific Method Prelab Assignment Before coming to lab read carefully the following pages on the scientific method and then answer the prelab questions at the end of this lab handout. Be prepared to discuss and/or hand in your responses to the prelab questions at the start of lab. Introduction Biology is a dynamic field of study whose aim is to unravel the mysteries of life itself. Throughout history‚ humans

on cardiovascular functions such as pulse rate‚ pulse lag‚ the PT interval‚ the TP interval‚ systolic‚ and diastolic blood pressure is noticeable after running down the steps of Long Hall and back up to the third floor. As Table 1 shows‚ the data support the initial hypothesis that the pulse rate will increase‚ the pulse lag will decrease‚ both the PT and TP intervals will decrease‚ and the systolic and diastolic blood pressure will increase. The pulse rate mean before exercise was about 78 beats per

hypothesis for the Blood Spatter Lab is that if blood is dropped from a pipette from gradually increasing heights‚ the diameter of the blood drops will increase at a constant rate. The hypothesis was proved correct because in the experiment‚ the higher the height the blood was dropped from‚ the larger the diameter of the blood drop. The data collected in the experiment represents the height the blood was dropped from over the diameter of the blood drop. The data shows that the higher the blood is dropped

Topic: Human Cardiovascular Physiology- Blood Pressure and Pulse Rate Determination. Hypothesis: Exercise can raise the blood pressure and the pulse rate. Aim: To determine the effect of exercise on the blood pressure and the pulse rates of students in the class. Introduction: The blood pressure of a person is the force exerted by the blood on the walls of the arteries per unit area. The blood pressure unit is mmHg. The blood pressure of an individual is expressed in two ways‚ the systolic (due

Analysis of Orthostatic Vital Signs The purpose of this assignment was to measure‚ document and analyse six recordings of orthostatic blood pressure‚ orthostatic pulse and respiratory rate on my lab partner. Orthostatic Hypotension is a condition when there is a drop in systolic pressure of more than 20 mm Hg‚ or orthostatic pulse increases of 20 bpm or more which occurs due to a quick change to a standing position (Jarvis‚ pp. 163). Six recordings were taken over a certain period of time to better

Abstract The objective of this study was to observe and record the effects that exercise has on cardiovascular functions such as mean blood pressure‚ cardiac output‚ and total peripheral resistance by comparing each numerical function’s numerical data before and after exercise. Before exercise‚ the mean blood pressure (MPB) was 84.03 mmHg with a standard deviation of 10.3. After exercise‚ MBP was 92.19 with a standard deviation of 10.5. The cardiac output (CO) before exercise was 5.45 Liters/minute

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

The purpose of this lab was to find my and my fellow classmates resting heart rate and record it. There were seven people in the class and we all participated in this study. There are four places to check heart rate and they are in your wrist‚ the inside of your elbow‚ the side of your neck‚ or the top of your foot. Everyone used the wrist or their radial artery. We used our middle and index fingers to gently feel for the radial artery in each others pulse. I then counted the pulse for 10 seconds

This cycle is started by electrical activity that can be measured by an electrocardiogram. As the heart contracts‚ it pumps blood into the next section of the cardiac
