Subject 2 Compare And Contrast Essay

When comparing both subjects it is clear that Subject 2 (Humza) has a larger vital capacity and lower breathing rate than Subject 1 (Mohamed.S). This experiment clarified that many factors can be taken into account and influence vital capacity and breathing rates. Referring back to my hypothesis which states that height and physical activity are large factors, Subject 2 being taller required his body to take in more oxygen through his lungs as oxygenated blood coming from the heart needed to travel further distances (183 cm height). Which also allows for a larger diaphragm that creates a considerably larger surface area in the lungs, which receives a greater intake of oxygen, The size of the lungs are directly proportional to the vital capacity. Vital capacity is the volume of gas that can be exhaled by a maximal expiration from total lung capacity.
If an individual were to have a lower than regular vital capacity which would result in lower oxygen intake and less oxygen being diffused through the alveoli and into capillaries directly into the bloodstream. Being more physically active also factors vital capacity as while an individual is doing exercise they are required to intake more oxygen to muscle cells so they are able to undergo rapid cellular respiration. Because of the increase in oxygen intake over time which resulted from exercise the lung muscles become stronger and the diaphragm expands meaning that the same individual would now intake more oxygen at rest because their lungs are more
