Minute ventilation? Explain the muscle action associated with an increase in the volume of the thoracic cavity during inspiration. This means that VC = TLC - RV. This approach assumes that the patients can make a truly maximal inspiratory effort during exercise. b. What Is Residual Volume? - Verywell Health In contrast, when you take a deep breath and exhale, the amount of air expelled from your lungs is known as vital capacity, the very most your lungs can hold. Inspiratory capacity is the amount of air taken in during a deep breath, while residual volume is the amount of air left in the lungs after forceful respiration. Venture Capital: What Is VC and How Does It Work? - Investopedia However, it does not increase the size of your lungs or impact the volume of air you can get into or out of your lungs (VC). -Whitman's hand (lines 8-9).
