Vital capacity is the maximum volume of air you can expel after taking the largest breath you are able. It usually ranges between 3-5 L but depends on age, sex, height, as well as ethnicity.

What is vital capacity of lungs?
the vital capacity of lungs is 3.5 liters to 4.5 litres
What is vital lung capacity?
vital lung capacity is how much air remains in your lungs after you exhale
Name and explain the volume that make up vital capacity?
The vital capacity is the maximum amount of air that a person can expel from the lungs.
How does respiratory volumes relate to athletic performance?
The more athletic a person is the higher their vital capacity would be. Vital capacity measures the maximum amount of air that can fill the lungs. Someone who is athletic would be able to consume larger amounts of air into their lungs.
Why the vital capacity of a marathon runner is greater than the vital capacity of a nonactive people?
If a person exercises a lot, he or she will not only train his or her muscles, but also his or her lungs. And since the lungs are surrounded by muscles, you train these muscles too. So a marathon runner has stronger lungs, that have a bigger capacity, as the muscles that surround can contract and stretch farther than those of a nonactive person.
How does emphysema affect vital capacity?
Emphysema's effect on vital capacity increases as the disease progresses. Emphysema is a chronic obstructive pulmonary disorder (COPD) which obstructs the passage of air out of the lungs. As a person exhales with emphysema, the airways close prematurely which reduces the exhalation volume thus reducing vital capacity.
Why is female vital capacity lower than males?
vital capacity in females is less because of the structural difference in the chest cavity for example the size of the lungs is smaller in females and the size of rib cage is also less in them. the metabolic rate is also less in females that s why the vital capacity in females is less.
How does height affect vital capacity?
due to surface area. if you are taller your lungs will have a greater surface area which will raise the volume.
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 is the clinical significance of vital capacity?
It represents your maximum lung capacity minus the dead air space and the residual volume. It is the amount of air you can move after taking in the biggest breath you can and then blowing out all the air you can exhale. Some diseases reduce the vital capacity of the lungs and make it difficult to breathe.
What is the difference between Forced vital capacity and vital capacity?
there is no difference.
Why do smokers have a higher than average vital capacity?
Because, taller people have larger lungs, therefore meaning they can inhale more air in due to a bigger capacity of volume.
