Physiology of the Circulatory System AP Biology

Abstract <Tab/>This laboratory's purpose was to show us how to determine one's blood pressure and the different factors that affect blood pressure and pulse on a person while testing one's own fitness level. After 15 seconds of exercise, my pulse had risen to 196 beats per minute. By doing this, we saw how resting required the heart to beat less because les oxygen was needed and that during exercise, more oxygen is …

…pressure on the heart. After exercise I had a pulse of 196 beats per minute, which does not seem right. Not knowing this before hand, it is not certain that we were breathing consistently throughout the tests in order to get an average. I can recall taking slow deep breaths and then trying to catch my breath. This may have skewed results as well. Works Cited 1.
