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

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

Analysis: 1. Explain why blood pressure and heart rate differ when measured in a reclining position and in a standing position. When a person stands‚ the heart must pump blood against the pull of gravity to reach important areas such as your brain. Veins must work hard to get blood back to your heart. As a person reclines‚ the heart does not have to pump as hard to reach the same areas‚ decreasing the blood pressure. Also‚ a person is usually more relaxed in a reclining position‚ which

Change in respiratory rate during exercise Aim: To record and investigate how the breathing rate varies for the duration of light and heavy exercise. Introduction: When an individual exercises‚ the muscles being used needs extra energy from oxygen. The lungs pump oxygen to the heart‚ and then the heart pumps the oxygenated blood through the blood to the particular muscle that is working. The human body has a series of organs working together‚ which is named the respiration system. The organs involved

Does Exercise Affect Blood Pressure and Heart Rate? Hypothesis If an individual is put through vigorous exercises‚ then his/her blood pressure and heart rate will be affected because of the increase in activity. Dependent Variables Heart Rate (measured in bpm) Blood Pressure (measured in mmhg) Independent Variables Height Weight Physical Fitness Speed on completing exercise Controlled Variables Types of Exercise Materials Cufflink Heart Monitor Test Subjects 1-5 Procedure

systolic blood pressure? Systolic blood pressure is the pressure exerted against artery walls created when the heart contracts to push oxygenated blood throughout the body. As blood pressure is represented by 2 numbers‚ systolic blood pressure is the upper number. A normal systolic blood pressure is 120 or below although it largely depends on the physical properties and capabilities of the individual. Q 2) what do you understand by the term diastolic blood pressure? Diastolic blood pressure indicates

Heart rate investigation Research statement: To investigate‚ how diabetes affect a person’s heart rate during physical exercise. Background information: Heart rate : Heart rate is the number of time a persons heartbeats per unit of time‚ usually measured in BPM (beats per minute). Heart rate is measured by finding the pulse on body‚ usually taken from carotid artery‚ which supplies blood to the head and the neck and radial artery‚ which Is located on your wrist below your thumb

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

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

the “Blood Pressure and Pulse Experiment” is to determine how postural changes‚ exercise and cognitive stressors affect blood pressure and heart rate. Background The pressure of blood in the circulatory system is‚ also known as blood pressure (BP) is “the force exerted on a vessel wall by contained blood. This is expressed in millimeters per mercury (mmHg)” (Marieb & Hoehn‚ 2016‚ pp. 708). There are two parts to blood pressure: systolic pressure and diastolic pressure. “Systolic pressure is the
