Homeostasis Lab: Human Anatomy And Physiology

Lab Report – Human Anatomy and Physiology Your name Your Institution of Affiliation March 26, 2018 Introduction: Homeostasis is defined as the “the tendency of a system, to maintain internal stability, owing to the coordinated response of its parts to any situation or stimulus that would tend to disturb its normal condition or function” CITATION Dicnd1 \l 1033 (Dictionary.com, n.d.). As the optimal balance for the body’s system is important, in most cases the body would tend to elicit responses that helps it to return to its optimal conditions. In this laboratory experiment, the researchers tried to measure the body’s ability to return to a “relaxed state” after exercising. Particularly speaking, exercises and other strenuous activities does not only consume the body’s internal resources. Rather, it also generates heat that is needed to be expelled by the body in order for it to return to a normal rate. This need, together with the increasing requirement of the body for re-oxygenation, is one of the main reasons as to why the heart rate, breathing rate, and pulse rates go higher. The dilation of the blood vessels that help in the dispersion of internal heat also makes the skin red CITATION Jam17 \l 1033 (James, 2017). Nonetheless, in order to measure these more specifically, the researchers would measure the heart rate, breathing rate, perspiration, and level of redness after the exercise. Based from previous ideas on how homeostasis works for the body, the researchers believe that the greater the intensity of the exercise, the more heat the body needs to expel. Thus, this causes an overall increase in heart rate, breathing rate, perspiration and redness (due to the dilation of blood vessels). Materials Needed:The materials needed for this experiment are: * Hand-held mirror or phone with a camera * Pen * Timer or stopwatch * Paper Procedure: To start the experiment, the researchers first readied all the equipment needed and prepared the tables where the results would be categorized. While doing, this certain classifications were made in order to provide a more quantitative description for some of observations that would be made. In order to classify the sweat, the classifications profusely, average, mild, and none, which ordered from the most to the least was made. As for the redness, the researchers preferred to use the classification based from their observations of strenuous activities. From the most red to the most pale, the authors classified the color as dark red, mild red, pink, and brown (or normal color). The paces of strenuous activity that were then utilized were as follows: (1) completely sedentary, (2) walking slowly, (3) walking fast, and (4) jogging. In order to make sure that the more strenuous activities would not affect the amount of imbalance within the body, the experiment stated by implementing the least ...
