given to the movement of air in and out of the lungs; the rate of pulmonary ventilation is defined as the tidal volume multiplied by the number of breaths taken per minute. Tidal volume is the volume of air breathed in or out during one cycle of quiet breathing. There are a few different factors that can affect the pulmonary ventilation rate but the most common and often most noticeable variation in pulmonary variation rate occurs during exercise. During normal quiet respiration‚ the average person

arterial blood pressure. Questions: 1. My blood pressure for this lab was 123/78. These numbers are normal‚ compared to the normal rating of 120/80. My pulse pressure was 45 (SP – DP). My mean arterial pressure was 93 (DP + 1/3 (SP – DP). 2. Mean arterial blood pressure is determined by cardiac output and total vascular resistance. The mathematical equation for mean arterial blood pressure is equal to cardiac output x total vascular resistance. The amount of blood pumped out of the heart is the

Heart Rate Vs. Exercise & Gender Introduction The purpose of this experiment was to find out whether males or females of the same fitness levels had a higher increase in heart rate after performing the same exercise in the same amount of time. The hypothesis was that‚ with the same levels of fitness‚ females would have a higher heart rate. The main reason that this hypothesis was thought to be viable‚ was because females generally have higher heart rates than males due to their smaller heart size

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 “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

Low Blood Pressure? Low blood pressure is not always a sign of a problem. But if you have symptoms of low blood pressure‚ your doctor can diagnose the condition and uncover the cause. Symptoms of dizziness and lightheadedness when you stand up from sitting or lying down -- with a decrease in your blood pressure -- may indicate a condition called postural hypotension. A wide range of underlying conditions may also cause your symptoms. It’s important to identify the cause of low blood pressure so appropriate

Aim:The aim of this practical is to investigate the effect of exercise on heart rate and breathing rate. We will use a digital heart rate monitor strapped on our chest while we perform different levels of exercise. A digital watch is also provided which receives signals from the heart rate monitor and displays your current heart rate on the screen. To measure the breathing rate at different levels of exercise‚ we measure the breathing rate before physical activity by counting the number of breaths

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

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

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
