What is the maximum amount of air that can be expired after maximum inhalation known as vital capacity?

Vital capacity refers to the maximum amount of air a person can expel from the lungs after fully inhaling. In healthy adults, vital capacity is typically in the range of 3000 mL to 6000 mL, depending on factors such as age, sex, body composition, and physical conditioning. The upper limit of this range correlates with the answer provided.

The value of 4800 mL represents an average or commonly accepted measurement of vital capacity for an adult, making it a reasonable representation of the volume of air that can be forcibly exhaled after maximum inhalation. It's a critical measurement in assessing lung function and overall respiratory health, as it reflects the ability of the lungs to hold and expel air efficiently.

This measurement is significant not only for understanding respiratory mechanics but also for diagnosing conditions that affect lung capacity, such as restrictive or obstructive pulmonary diseases. In contrast, the other volumes provided in the choices are generally below typical vital capacity for a healthy adult and do not represent the maximum air that can be expired after maximum inhalation.
