Vital demands for the body. Allergic reactions

0 Comment

Vital lung capacity can be affected by both environmental and physiological factors (Lumb, & Lumb, 2016). For instance, pregnancy can lower the vital lung capacity in women. When a woman is pregnant, the uterus compresses the diaphragm thus decreasing the lung capacity. Diseases such as asthma can affect the total lung capacity since they constrict the parts of the respiratory system thus allowing less air into the lungs.  Analysis of part twoQuestion five     Graph twoQuestion 6 The breathing and heart rates increase with an increase in activity. During rest, the breathing rates are low since the body doesn’t require much energy (DiGiulio & Napierkowski, 2014). When performing energy demanding tasks, the breathing rate increases as the body needs more air to sustain the body’s activities.Question 7 There are many things that affect a person’s breathing rates. Exercise and allergic reactions are a few of the main factors that affect the breathing rates (Yoost & Crawford, 2015).  During aerobic exercise such as jogging as seen in this experiment a person breaths more to meet the air demands for the body. Allergic reactions such as pollen also affect the rate of breathing. Substances released during allergic reactions blocks the airways thus forces the breathing rates to increase.Question 8 The human body uses oxygen as for energy production purposes. Oxygen in our bodies issupplied via the bloodstream. As such, this results in a direct relationship between physical activities, breathing, and the heartbeat rates. However, sometimes the physical activity rates can exceed the maximum heart and breathing rates. During such moments, energy is produced without oxygen. By combining anaerobic and aerobic activities, one can increase his or her strength, cardiorespiratory fitness, and training gains.Question 9 There is a correlation between activity and heartbeat rate. During exercises, the rate at which energy is needed in our body increases. The need for oxygen is increased too. As such, the breathing and pulse rate increases. One’s pulse is used as an indicator of heart rate as the arteries in all parts of the body expand when blood is pumped out of the heart (Feuerstein, & Kuczmierczyk, 2013). The heart increases its speed to pump extra oxygen and nutrients or food to the muscles. Breathing speeds up the rate of oxygen intake while and helps get oxygen outside the body. When a fit person, for instance, an athlete exercises, breathing rate, lactic acid levels and pulse rate rises further than in an unfit person (In Kasper et al.,  2015).  In a person who is feet health wise, the recovery time is usually shorter. Conclusion  From the above experiment, I was able to see breathing and heartbeat rate increases with increased activity. My data might not be 100% correct or reliable since the measurement that I used was not so good since I measured 30 seconds then multiplied by two. In my opinion, measuring in 60 seconds would make more accurate lab. More accurate results could have been obtained by measuring 120 seconds then divide by 2. This could have been more accurate since when I multiplied by 2 the results might have gone up by 1 heartbeat wrong, by the end of the practical I could have ended up measuring eight heartbeats wrong per minute when I started measuring up to 1 heartbeat wrong. If I measured 60 seconds, it could have been up to 1 wrong which means by the end of the experiment I could go up to two heartbeats wrong.  For instance, if the accurate heartbeat/min is around 70, I would have obtained a value somewhere between 60bpm and 80bpm is I measured at the 30s. A measure at the 60s would give a value between 66bpm and 74 bpm which in my opinion would be more reliable. More accurate results could have been further obtained by using breathing meter and a professional pulsed and have an object to make the test person learn exactly the same activity. The resting breathing and heart rate was higher than normal because most probably the real resting breathing or pulse was not measured. Most probably the persons were not fully relaxed.
