The lung capacity vary on the person's age, gender, where he lives and more. For example, if he lives in a smoke-free area his lung capacity is probably more. The average lung capacity for a human is 4-6 liters of air and the average lung capacity for a 10-11 year old is around 4 liters.
approximatly 5 and a half (5.5)
Depends on the boy
I work in a hospital as a respiratory therapist. Part of my job is mechanically ventilating people. A good guideline is 5-12 ml/kg for adults and 5-10ml/kg for infants and children. This is based on their ideal body weight (IBW). So an average adult is about female is about 70kg. Lets use 8ml/kg that would mean her lung capacity or tidal volume is approx. 560ml (70kg x 8ml/kg). So a child that is 60lbs would be around 27kg. If we use 8ml/kg to figure out their tidal volume it would be 216ml. Total lung capacity would likely be slightly more since we have a residual volume of air that we breath out only when we use force to exhale.
Are you looking for actual size or for capacity. I believe the capacity is are 1.5 quarts, but it has the ability to expand.
1.8cm width, with a capacity of around 2ml.
to be honest there is no average to this.It all really depends on the persons brain size and capacity.
Men have larger lung capacities than women. Tall people also have larger lung capacities than short people. It is said that people aged 20-25 have larger lung capacities than other age groups, Its because by the time you have reached your twenties your lungs have reached their full capacity, but when you are a kid then your lungs aren't fully developed so they don't have a large capacity. From when you are 20 your lung capacity starts going down so an old man has about the same lung capacity as a very small boy.
The alveolar macrophage is important in the defense of the lung and may be the pathogenesis of lung disease. Cell counts in bronchoalveolar lavage fluid have lead to the conclusion that smokers have an increased number of alveolar macrophages but have not enabled the number to be related to a measure of lung structure.

Mmmmm . . . about 2500 cc's, I imagine. Mine is 4100 cc's and my old dad's is about 1200 cc's.
It means that 23% of the lungs are not functioning, normally from smoking. Because someone is 74 years old does not mean that they should suffer from reduced lung function.
