Affects of Physical Activity on the Heart Rate And Blood Pressure Essay

PurposeThe laboratory prep argond depart teach you how to measure channel drag. Learn where systolic and diastolic hale begins. Next observe venous return, nubble rate, and derivation drive in three variant scenarios including normal range, resting rate, and increase exercise. researchIn the circulatory system lab, students observed how physical activity affects prodigal gouge and kernel rate. With a conk outner, one students obligate was recorded at basal (normal) rate, lying down, and afterwards exercising. Normal air pressure is systolic long hundred and diastolic 80. A normal embrace rate is 60 vanquish per minutes. Systolic pressure is the pressure of fall during contraction and would be considered as the beginning twitch of the stethoscope. Diastolic pressure is the pressure in the rootage vessels in betwixt boldnessbeats at a relaxation point and would be the last twitch before the plague drops completely on the stethoscope.These points are considered a s lub & dub. Lub or S1 is the first heart beat and the closing curtain of the tricuspid & bicuspid valves. The second heart beat, s2 is dub, the closing of semilunar valves. Blood pressure and heart rate increase after physical activity due to the fact that the dead body uses more group O and releases naughty volumes of carbon dioxide. In our experiment the test subject inevitable more atomic number 8 while exercising. The 25 jumping jacks preformed change magnitude blood pressure and heart rate. If the test was preformed on a different test subject results may tack, depending onbody mass, weight, height, male or female.HypothesisIf physical activity increases, then blood pressure and heart rate will rise.MaterialsStethoscope Test subject Watch Administer Sphygmomanometer (Blood pressure cuff)ProcedureSee Lab 4 The Circulatory System 2013 eScience Labs, LLC, 10/21/2014.Data/ResultsTable 2 Blood Pressure and trice ReadingActivityBlood Pressure(mmHg)Systolic/Diastolic trice (beats/minute)Basal (Normal) one hundred twenty/7560Lying down120/6056After exercise140/8068Lab Questions1. What is systolic pressure?Systolic blood pressure is the pressure when the heart ventricles contract and pump blood out of the heart. This is the highest pressure in the blood vessels.2. What is diastolic pressure?Diastolic pressure is the pressure between heart beats when the heart ventricles are resting and filling with blood. This is the lowest pressure in blood vessels3. wherefore is pressure a sensible instruction to circulatory health?Because through pressure, people can determine how much(prenominal) blood are pumped out of the heart in a single contraction. A person with a healthy circulations blood pressure should be at the normal level.4. Explain the lub-dub sounds of the heartbeat?Lub-Dub is the first and second heart sounds that are clearly heard with a stethoscope. These sounds are the closing of the heart valves. The first heart sound, know as lub starts when the ventricles contract. The auriculoventricular valves are closed and the blood is pumped out of the heart. The second heart sound, known as dub, starts when the ventricles relax. The semilunar valves are closed and the ventricles are filled.5. Why do blood pressure and heart rate change after exercise?The muscles in the body need more oxygen during exercise. The heart then pumps more blood to the lungs for gas exchanging. Since the heart needfully to contract harder, the blood pressure and heart rate will be increased.6. How might the results in Table 2 change if someone else completeed the activities? Why?The results in Table 2 would be lower or higher if someone else performed the activities because the sex, height, weight, and health could also affect the results.7. Why is it important for blood to flow in only one direction?Every part of human body needs oxygen in order to perform works properly. Oxygen-rich blood supplies oxygen needed to every part of the body and oxygen-p oor blood needs to flow to the lungs to exchange gas. If blood flows backward, the body will not get the oxygen it needs to maintain normal homeostasis therefrom it will be under a serious threatening.Conclusion/ handlingIn this experiment, we saw that the blood pressure and heart rate substantial increased after the subject exercised. From table 2, we saw that the blood pressure increased from 120/75 to 140/80 and the pulse increased from 60 beats /minute to 68 beats /minute after exercised. The rate of blood pressure and pulse were lowest when the subject be down, which only 120/60 mmHg for blood pressure and 56 beats/minute for the pulse. Since the blood pressure and heart rate raised as body movement increased, we concluded that this is a statistically significant result. possible actionBlood pressure measurements generally reflect arterial blood pressure. The high and low points of blood pressure are expressed in millimeters of quicksilver (mmHg). The normal blood pressure i n healthy individual is 120/80(mmHg). Blood pressure is usually measured with the sphygmomanometer (blood pressure cuff) which normally still of a cuff with an inflatable bladder and a mechanical manometer with a rubber bulb.
