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

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

Abstract: In this report you will learn of how my group and I performed our lab on blood pressure and what the results mean. We found the blood pressure before and after sixty seconds of jogging in place to see the effects. We found that after the physical activity the subject’s blood pressure was higher. From this we take away that physical activity does have a significant effect on the heart and blood pressure. Background: Blood pressure is the measured force applied to the artery walls as

Using A Pressure Canner 1. Begin by adding two or three inches of hot water to the canner‚ more if specified in the recipe. Place the filled jars on the canner’s rack‚ making use of a jar lifter. Ensure the jar remains upright at all times‚ and position the lifter so it sits just below the screw band. Fasten the lid on the canner securely. 2. Leave the weight off of the open petcock or vent port‚ as described above. Heat the canner at the highest temperature until the steam begins to flow freely

overall purpose of the experiment is to observe the change of pressure as three different gases; N2‚ He‚ and an unknown gas effuses through a pinhole into a vacuum environment. Each gas has a different pattern of changing the pressure depending on its molecular mass‚ which is related to the kinetic theory of gases‚ where heavier gases (N2) effuse slower than lighter gases (He). The experiment setup was prepared‚ measurement of change of pressure as a function of time were recorded. After performing two

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

synthetic blood samples through a process called blood typing. According to Fredrick H. Martin‚ PhD.‚ et.al‚ blood typing is a test that determines a person’s blood type by checking the blood for the presence or absence of specific glycoprotein called antigens found on the surface of the red blood cells. The two clinically relevant antigens are the A antigen and B antigen. The blood type is named based upon which antigen is present on the surface of its red blood cells. There are four blood types.

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

Mechanisms of Blood Flow in the Human Forearm during Mental Stress‚ Following Isometric Exercise and after Occlusion ------------------------------------------------- 1. Introduction A common technique in measuring blood flow in the human forearm is by venous occlusion plethysmography. The fundamental principle is that if the venous return from the arm is blocked‚ the forearm will swell at a rate relative to the rate of the arterial inflow (Whitney‚ 1953). However‚ the rate of increase in volume

The History of Blood Pressure Finding out someone’s blood pressure is very important. Johannes Müller once said‚ “The discovery of blood pressure was more important than the discovery of blood.” Someone’s blood pressure could be high‚ and no one would know. The reason being is that a person with high blood pressure‚ also known as hypertension‚ will usually have no symptoms. High or low blood pressure cannot be detected without being measured. High blood pressure could cause heart attacks‚ strokes
