The lungs lose elasticity so they expand less.
Pneumatic changes in the lungs refer to the expansion and contraction of the lung tissue in response to changes in air pressure during breathing. The diaphragm and intercostal muscles work together to increase lung volume during inhalation, creating negative pressure that draws air into the lungs. During exhalation, the muscles relax, and the elastic recoil of the lung tissue expels air out of the lungs.
yes, sadly you can get lung cancer at any age.

The bell jar model of the lungs is a simple representation that helps illustrate how changes in pressure impact lung volume and air flow. It is useful for conceptualizing basic principles of lung mechanics, such as inspiration and expiration. Additionally, it can assist in understanding the relationship between pressure differentials and lung expansion.
Bilateral atelectatic changes refer to the collapse or incomplete expansion of lung tissue in both lungs, often resulting from factors such as obstruction of airways, prolonged inactivity, or fluid accumulation. This condition can lead to decreased gas exchange and reduced lung capacity, potentially causing respiratory distress. It is commonly observed in patients with certain medical conditions or after surgery, particularly in those who are unable to take deep breaths or cough effectively. Treatment typically involves techniques to promote lung expansion, such as deep breathing exercises and physiotherapy.
These are a category of extrapulmonary, pleural or parenchymal respiratory diseases that prevent lung expansion leading to a decreased lung volume, an increased in breathing difficulty and inadequate ventilation.
Yes age does make a difference in lung capacities because as you get older your body changes such as how you breathe, when you get tired while running for a short time, and how you can eat more than someone else younger than you.

Yes, as you age, your lungs undergo several changes. The lung tissue can lose elasticity, making it less efficient at expanding and contracting. Additionally, the strength of respiratory muscles may decline, and the airways can become more rigid, which can affect overall lung function. These changes can lead to a decrease in lung capacity and efficiency in gas exchange.
It can happen at any age

It may mean that there are changes in how much the patient is able to exhale into the mylar balloons frequently used to measure lung function.
