Homeostasis Research Paper

We conducted a study, 2 subjects took their blood pressure and pulse before exercise, immediately after exercise and 5 minutes after exercise, their appearance and sweating was also noted. This table shows that before exercise both subjects had relatively normal blood pressure, immediately after exercise both subject 's blood pressure had dropped. The blood pressure was retested after 5 minutes of rest both subject 's blood pressure risen back up to a normal level. Before exercise subject A 's pulse was average, after exercise it had risen to compensate for the need of oxygen to get around the body quicker. After 5 minutes this had then returned back to a normal pace when the body had relaxed. Subject B had an average pulse before exercise, immediately after exercise it had risen, 5 minutes after exercise it had dropped again to a normal pace. the differences in pulse shows that subject A is healthier than subject B because the difference between subject A 's resting and exercise

P6- follows guidelines to interpret collected data for heart rate, breathing rate and temperature before and after a standard period of exercise

The researchers addressed known influential factors verbally, but not all factors were controlled during the experiment. For example, time of day, the white coat effect along with respirations and heart rate were not addressed in the results.

To examine dynamic exercise which is the independent variable of this experiment and obvserve the changes it had on HR, SP, DP, PP and MAP.

This experiment will involve five individuals putting their left hand in different samples of water of varying temperatures. Their blood pressure and heart rate will be recorded before the experiment, and after each water trial, to determine the effect it has on both the blood pressure and heart rate.

Blood pressure, heart rate, respiration rate, and body temperature of your child will be measured.

Results:Table 1 shows that the subjects mean bpm was highest after exercise (start of recording) at 88.20 BPM and lowest while sitting and breathing regularly at 60.97 BPM. The range of BPM was also the largest after exercise (start of recording) at 74.07-135.14 BPM. Table 2

The purpose of this experiment was to determine the subjects’ ventilatory response during incremental exercise. The equipment we used in this experiment was the cycle ergometer, and in addition we had to test the subjects’ ventilatory response during rest and recovery. In this experiment, we have two subjects with different fitness levels, which fortunately make the subject pool in this experiment very diverse. In addition, the purpose of this experiment is to determine the relationship between ventilatory response, ratings of perceived exertion, heart rate, and blood pressure in rest, exercise and recovery and the intensity and the duration of the exercise in this experiment for each subject are equal.

Determine who is the subject the person exercising and the experimenters and the person taking and recording the data the experimenters will take the subject standing heart rate temperature and breathing rate as well as make observation on the subject color and perspiration heart rate are obtained by taking the radial pulse or carotid pulse for 10 seconds convert all your heart rate to beats per minute by multiplying by 6 and record

As previously stated the purpose of homeostasis is to maintain a constant internal environment. There are different components that enable this to happen within all control systems and these are: The Sensor, which senses and monitors the external and internal changes within a system; the sensor is generally the hypothalamus located within the brain. The sensor sends a signal to the controller; which is in charge of the effector. Once the controller has been given a signal it will either switch the effector on or off depending on what is required and the effector will generally secrete a hormone to change the state of the internal environment. The output will be the changes that have taken place. After this there is a mechanism called negative feedback, negative feedback is a vital part of homeostasis as it reverses the original changes that have taken place to maintain equilibrium within the body.

There is increased perspiration to cool the body and maintain the body temperature as the delicate metabolic state (due to the exercise) produces heat. Lactic acid builds up during the anaerobic respiration, especially in the muscles. This creates and oxygen debt, homeostasis is used to balance this debt and therefore remove lactic acid from the body because it is toxic, thus breathing rate is also increased.

Body temperature graph: In the 3 minutes before exercise Student A had a body temperature of 37 while the other student’s temperatures slowly dropped. Once the race started their body temperatures slowly raised and then balanced out. Between 15 and 21 minutes Students A, B & C’s body temperatures slowly decreased until they balanced out again.

Homeostasis is the process of maintaining ideal conditions and being able to stabilize those conditions. When we exercise, our muscles require more oxygen to work. Guyton (1985) says that our blood flow increases dramatically to our muscles during exercise to about 20 L/min, compared to that of 1 L/min when we are resting. Usually, our precapillary sphincters to our capillaries in our muscles are contracted to about 20-25% open, restricting the amount of blood flow that goes to the muscles. When we become more active and the muscles require more oxygen, the precapillary sphincters dilate so all of them are open, and the blood flows to the muscles, giving them the oxygen they need to keep up with the demanding actions we

Carry out an experiment to measure the heart rate and ventilation rate before, during and after moderate exercise.

The purpose of this investigation is to find out how our bodies regulate our heart rate in order to maintain homeostasis with respect to temperature while jump roping at different times. The relationship between feedback mechanisms and homeostasis will be explored in this lab.
