At the end of all those little branches are air sacs, called alveoli. Lung volume increases as height increases. The total lung capacity of an adult human being is about 6 litres of air and the capacity varies with the sex of an individual. It may seem odd to think of muscles when you talk about your lungs, but actually several are involved. Breathing rate usually does not change with age. The maximum amount of air your lungs can hold—your total lung capacity—is about six liters. Decreases in measures of lung function such as vital capacity (the maximum amount of air that can be breathed out following a maximum inhalation) How does body size affect lung capacity?

Smoking can cause fatal diseases such as pneumonia, emphysema and lung cancer. Apparently then in most fit, healthy subjects the age related decline in V ˙ O 2 max and in pulmonary O 2 transport capacity are similar. X-rays showed that calcification increased from 6 percent in a person’s 30s to 45 percent in their 90s.
