The Respiratory System:

Extracts from this document...

Introduction

The Respiratory System: Tidal volume: volume that flows into the lungs with each inspiration during quiet breathing. Inspiratory Reserve: air inspired with a maximal inspiratory effort in excess of the tidal volume. The mean for this is 3.3 in men and 1.9 in women. Expiratory Reserve: volume expired by active expiration after passive expiration the mean scores for this is 1.01 in men and 0.7 in women. Vital Capacity: maximum breath volume. In this second part of the essay we had to compare the results of the tests we under took. The test we did was using a spirometer, we collected respiratory activity, of a few people in our group, compared them and see what factors could affect lung capacity. Subject A (female) Emma holder Tidal Volume = 23mm (average) ...read more.

Middle

Therefore we can see that subject C has the biggest lung capacity and subject A has the smallest lung capacity. But why are the reasons for people having different lung capacities? This is down to several factors: Physical exercise or fitness. People who exercise frequently usually have larger lung capacity than those who are primarily sedentary. As this makes the lungs more efficient at gas exchange (explained in first part) Lack of exercise is one of the risk factors that contributes to the development of heart and blood vessel disease. Reducing your risk of developing heart and blood vessel disease may be as simple as getting up and exercising a few times per week. This can not be the only reason why subject C has the bigger lung capacity as both subject B & C take part in more physical exercise, in fact Subject B takes part in more exercise as he is part of a football academy where as subject C is just part of a Sunday rugby team. ...read more.

Conclusion

As well as they are both similar height of about 5"9. Posture problems: rounded shoulders or slouching can lead to smaller lung capacity. This is because your vital organs are in the right position and can function at peak efficiency. Good posture helps contribute to the normal functioning of the nervous system. Without good posture, your overall health and total efficiency may be compromised. Because the long-term effects of poor posture can affect bodily systems (such as digestion, elimination, breathing, muscles, joints and ligaments), a person who has poor posture may often be tired or unable to work efficiently or move properly, as they are getting less oxygen. But this is hard to determine whether subject B is more sloughed than Subject C. But as the difference between Subject B & C is so little there are many factors but they are so little, therefore it can be hard to determine. ...read more.

    The diaphragm also moves upwards in order to increase the expiratory volume. Over exertion during exercise can mean that not enough oxygen is being inspired. A lack of oxygen to the brain can cause the athlete to collapse. The long-term effects of exercise on the breathing system are; increased lung capacity.
