Heart Rate and Mean Arterial Pressure

Title : The Effect of Exercise in the Blood Pressure and Heart Rate

Introduction

Exercise is one of the best ways of getting a healthy mind and a healthy body . But as we all know there is a major role of this exercise in the circulation of our blood , and also to our circulatory system . There are some changes that take place with regards to the circulation of the blood in our body before the exercise and after doing it

Blood pressure is an important measure of the state of the heart and

blood vessels . It is defined as the force the blood exerts against the blood vessel walls . The pumping action of the heart generates a blood flow through the vessels . When resistance from vessel walls , blood pressure results , meets this flow . Blood pressure is usually read as the systolic pressure over the diastolic pressure . Systolic pressure is the pressure in the blood vessels when the ventricles of the heart contract while diastolic pressure is when the ventricles are relaxed . The two pressures are obtained by creating a pressure great enough to stop the flow of blood through the artery that is being tested . This can be detected by the ability to hear blood squirting thought the vessel each time the heart contracts . The first heart sound that is detected through the stethoscope is the systolic . Heart sounds will be heard until the pressure is low enough on the arm that diastolic pressure has been reached . Caution must be used when measuring blood pressure over several hurried measurements . It is preferable to take one measurement carefully , repeating for uncertainty and distraction . The measurements will also vary according to the time of day , meals , smoking , anxiety temperature and season of the year . Treatment of high or low blood pressure is frequently encountered in the field of medicine . It is important to remember that the treatment should not be based primarily on one measurement , but on the patterns of blood pressure change during a period of observation

A normal heart receives oxygenated blood , denoted in red (right entering via the left and right pulmonary veins . Upon contraction blood is forced out of the left ventricle through the aortic valve and out to the rest of the body . Blood that does not contain oxygen , seen in blue above , is forced out of the right ventricle through the pulmonic valve and into the lungs . A pulse is felt because of the flaring of the aorta as the ventricle of the heart flares . Obtaining a pulse rate is important in determining how hard the heart is working and if a blood flow to a specific limb or body region is normal . The purpose of this experiment was to allow students to determine resting heart rate (pulse in beats per minute and to demonstrate the effects of moderate exercise upon the heart rate
