My The increase in breathing rate enhances the

My hypothesis was validated. After doing the experiment and obtaining calculations I was able to find that Subject #2 did in fact have a higher respiratory rate and vital capacity. Temperature directly affects breathing and rate of respiration. When your body temperature rises because of an infection, it’s called a fever. The purpose of a fever is to raise the body’s temperature enough to kill off certain bacteria and viruses sensitive to temperature changes. Due to the high body temperature of subject #2 her breathing rate was increased. As temperature increases, so does respiration rate; as it decreases respiration rate slows. One of the reasons this happens is because our body is trying to maintain a normal body temperature (normal body temperature is 37 degrees Celsius a fever is officially diagnosed when the body temperature is more than 38 degrees Celsius). The increase in breathing rate enhances the cooling of the body due to the exhalation of water vapour. Furthermore, in my hypothesis I also predicted that subject #2 would have a higher vital capacity, this was also proven to be true. Taller people regardless of their age or gender usually have a higher lung capacity than shorter people. This is because their diaphragm is larger and the total oxygen intake is also larger. Additionally, their lungs are overall bigger. As a result, they are able to intake a lot more air volume and for that reason it increases their vital capacity. In conclusion, there are many determents that shaped our results. However, these are the main reasons as to why I believe that Subject number 2 would have a higher vital capacity and lower breathing rate

There are many experimental errors that may have skewed our data. To start, one aspect that most likely influenced our results was the process of removing your mouth from the mouth piece. This included removing your mouth and the quickly using your hand to cover the top of the mouthpiece to ensure you wouldn’t lose the air within the volume bag. However, during the time it took to place one’s hand against the mouthpiece air was lost, due to the time gap between the covering of the mouth piece. This is an element that most likely altered our results. Furthermore, another component that was indefinite, and swayed our results was that the subjects were conscious of their breathing rate. It is known if you make a conscious effort to inhale and exhale you wont inhale or exhale the same amount of air you normally would. For example, you will take and exhale either too much or less air. This could affect our calculations where we were asked to normally exhale or exhale as well as when the subjects were asked to count or measure their breaths per minute. All in all, these are the two experimental errors that hugely impacted our data, outcome and results, rendering them not as accurate as they could be.
