Determining Lung Capacity

Determining lung capacity

Experiment:

This is the experiment of determining lung capacity. All the students in the group measured three types of different parameters: vital capacity, expiratory reserve and tidal volume.
“Lung volumeizing refer to physical differences in lung volume, while lung capacities represent different combinations of lung volumes, usually in relation to inhalation and exhalation.The average pair of human lungs can hold about 6 liters of air, but only a small amount of this capacity is used during normal breathing.
Several factors affect lung volumes, some that can be controlled and some that can not. Lung volumes can be measured using the following terms[1]:

Table 1

|Larger volumes |Smaller volumes |
|males |Females |
|taller people |shorter people |
|non-smokers |smokers |
|athletes |non-athletes |
|people living at high altitudes |people living at low altitudes |

The results that were measured during the experiment are showen in the table.
