Variables Affecting Human Arterial Pressure and Pulse Rate BIOL-204 Introduction: The woozy feeling when standing up too quickly. After going for a run‚ feeling as if one more beat and the heart would project itself out of the chest. Or quite the opposite and being in a very relaxed state. These are all changes one experiences at some time or another. What causes the different feelings and how each variable affects pulse rate and blood pressure has many wondering. Because of this curiosity

Blood Pressure The function of the heart is to circulate blood around the body. The heart comprises of four chambers: Right Atrium Left Atrium Right Ventricle Left Ventricle Functionally the heart comprises of two pumps: The right atrium receives blood from the body (de-oxygenated blood) and the right ventricle pumps it into the lungs for aeration (removal of carbon dioxide and add oxygen). The left atrium receives the oxygenated blood from the lungs and the left ventricle pumps

As blood flows through the body‚ it exerts stress on blood vessel walls; creating an effect known as blood pressure. Blood pressure is measured by “the force in the arteries when the heart beats (systolic pressure) and when the heart is at rest (diastolic pressure)” (American Heart Association [AHA]‚ 2008‚ para. 1). An average healthy adult’s blood pressure has a measurement of 120 over 80 or less (AHA‚ 2008‚ para. 3). “High blood pressure (also called hypertension) occurs when your blood moves through
Premium Hypertension Blood pressure Artery
known as high blood pressure‚ is the most common chronic cardiovascular disease in which the blood vessels (arteries) have persistently raised pressure. Blood pressure is the force of blood exerting against the walls of arteries as it is pumped by the heart through out the body. Therefore‚ hypertension occurs when the blood is pushes harder against the arterial wall. It is called the “SILENT KILLER" because it shows no signs and symptoms that is why it is important to check blood pressure regularly

The effect of different music styles on blood pressure Experiment by: Claire Mouser and Garrett Swearingen Written by: Claire Mouser Written: 3/13/14 Abstract: The purpose of this experiment was to inform teenagers about the effect different genres of music can have on your heart rate. The heart rates of teens are affected differently when they listen to rock versus classical music. The goal of this experiment was to find out whether teens heart rates would change while they listened

Exercise on Blood Pressure Katie Law-Balding June 28‚ 2010 Abstract The purpose of this experiment was to see what effect 30 seconds of physical activity would have on a subject’s blood pressure. In this case‚ physical activity is defined as stair running at a moderate pace for 30 seconds. Standing blood pressure was measured before and after physical activity for comparison purposes. Three trials were completed and initial blood pressure was 94/75 mmHg‚ 125/92 mmHg‚ and 106/92 mmHg. Blood pressure

Arterial blood pressure is "normal" when the systolic pressure is 90-119 mmHg and the diastolic pressure is 60-79 mmHg. When the arterial pressure is ≥120/80 mmHg‚ a person is considering being hypertensive [1-3]. According to U.S. national guidelines (JNC 7 Report and JNC 8 Report)‚ the following represents different stages of hypertension: Classification Systolic (mmHg) Diastolic (mmHg) Normal <120 <80 Prehypertension 120-139 80-89 Stage 1 140-159 90-99 Stage 2 >160 >100 Treatment of Hypertension

session. Blood pressure may be one of the least complicated to monitor‚ yet possibly one with the highest probability to bring on complications if left untreated. Blood pressure readings are measured in millimeters of mercury. An instrument called a sphygomanometer is used to measure your systolic and diastolic pressure. Written in the form of a fraction‚ the top number is the systolic pressure‚ and the bottom is the diastolic pressure. The systolic pressure is measuring the amount of pressure that

In our first lab‚ we started off calculating and documenting descriptive variables‚ Sex‚ Height‚ Weight‚ Age‚ Gender‚ Heart Rate and Blood Pressure both at rest and after exercising. The purpose of this was to be able to measure these methods as well as comparing the results of females and males for a class description. All students ranged in all the

Blood is moved from the heart to the body by arteries. Blood pressure is the force of the blood pushing against the walls of the arteries. With each heartbeat‚ blood is pumped into the arteries. Systolic pressure is determined when the heart is contracting which causes increased pressure in the arteries. Diastolic Blood pressure is the remaining pressure in the arteries when the ventricles of the heart is relaxed allowing the heart to fill with blood. Blood pressure is influenced by cardiac output
