Why does vital capacity gradually decrease with age?
Vital capacity decreases with age due to changes in lung elasticity, chest wall compliance, and muscle strength. These changes can lead to a decrease in the ability of the lungs to stretch and fill with air, resulting in a reduced amount of air that can be exhaled after a maximal inhalation. Additionally, age-related factors such as decreased respiratory muscle strength and changes in lung structure can further contribute to the decline in vital capacity.
What are four factors that can affect the vital capacity of a person?

Why vital capacity and maximal voluntary ventilation MVV decrease with age?
Vital Capacity gradually decreases with age because, as one ages, the elastic fibers in the lung gradually decrease as well. This results in less elastance and greater compliance of the lungs: think of an over stretched rubber band. Further, the muscles of chest weaken with age; hence, the lungs are unable to exert the same force to bring air in or out so the vital capacity (what we are able to breath in and out or maximal ventilation) is decreased.
What is vital capacity of lungs?
the vital capacity of lungs is 3.5 liters to 4.5 litres
What can reduce vital capacity?
There are many reasons that could increase or decrease vital capacity in a person. Respiratory conditions are a major factor in how much air a person can take in.
