Observing the Role of Homeostasis in the Body after Exercise

Observing the role of homeostasis in the body subsequently(prenominal) exercise biological science (T) Functioning Organisms Biology Practical Report 0383210 Mrs Woinarski Due 14th November 2012 instauration Homeostasis plays a vital role in the maintenance of a customary environment in which bodily governances are able to function nigh efficiently. The importance of homeostasis evict be seen in blood hale and neural impulse measure, as measurements which are not in the normal range force out create serious health problems. Exercise has a known number on two of these systems, as it proceedss in a rise in body temperature and distension of blood vessels, as well as an summation in breathing consider.By measuring how these rates return to normal levels afterward exercise demonstrates homeostasis in the body, and helps to describe the ways in which the endocrine system and organs involved impact this. Aim To demonstrate the role of homeostasis in r individuallying no rmal levels for pulse rate and blood storm after an increase due to exercise and investigate which of the relative feedback systems works meteoric to achieve homeostasis. Apparatus Stopwatch 1. 5m Skipping Rope Electric blood blackmail monitor MethodUsing the electric blood rack monitor, some(prenominal) blood force and pluse rate were measured at a resting level for the first player. In an open area, participant was asked to skip 100 time using rope, without any break. Immediately afterwards, the stopwatch was set and the blood pressure and pulse rate of the participant were measured using the blood pressure monitor and recorded. Using the stopwatch to see time after exercise, blood pressure and pulse rates were measured again at t=1, t=5 and t=10, where t equals minutes after exercising.The spotless process was completed on each participant individually.

As seen in graphs 1, 2 and 3 the trend was a peak in both bloo d pressure and pulse rate immediately after exercise, followed by a slower cliff to normal levels. Pulse rate, as seen in graph 1, assortmentd quite dramatically in participants 1 and 2 after exercise, and although this equal peak is not so obvious in participants 3 and 5, they show a similar pattern.The difference in shield of change here could be affected by many ungovernable variables, such as the participants fitness levels. However, by comparing each participants results to their resting levels, an accurate description can be made. Participant 4 is, in this case, an anomaly, as exercise did not have any effect on their pulse rate (Table 4). Graphs 2 and 3 show the participants change in blood pressure as a result of exercise, isolated into systolic and diastolic blood pressure measurements.Again, a peak can be seen immediately after exercise as blood is being forced doneout the body to supply nutrients to muscles which have just been used, shown in both systolic and dia stolic rates. Blood pressure returns to normal through a homeostatic process after exercise, as a result in the changing size of blood vessels. After blood pressure had returned to normal, in the majority of participants, it then in fact continued to decrease slightly before creating a new resting level. This is a result of the dilation of blood vessels, which then move much easily through arteries. inductionIn conclusion, the process of homeostasis in returning to normal levels of blood pressure and pulse rate after exercise have effectively been demonstrated. The unalike speeds at which these homeostatic processes are completed are a result of the endocrine feedback systems involved. Sources of error in the experiment are the limited results obtained as a result of time constraints. For a more accurate outcome, more participants should be tested so that any anomalies can be disregarded, and each participant should be tested multiple times to obtain comely results as a way to a void any mechanical errors.As the same device was used to test the blood pressure and pulse rate of each participant, mechanical error was reduced, however multiple tests would have change the results.
