Welcome to my KZbin Channel Power of Knowledge Academy. In this video you will learn about lung volume and capacities. Types of volumes like tidal volume, inspiratory reserve volume, expiratory reserve volume and Residual volume, Types of capacities like total lung capacity, vital capacity, functional residual capacity and inspiratory capacity.
Lung Volumes
Lung volumes refer to the different amounts of air that move in and out of the lungs during various phases of breathing. Here are the main components:
Tidal Volume (TV) - This is the amount of air you inhale or exhale with each breath during normal, relaxed breathing. It's typically about 500 mL in adults.
Inspiratory Reserve Volume (IRV) - After a normal inhalation, this is the extra amount of air that you can inhale with maximum effort. It's usually around 3100 mL.
Expiratory Reserve Volume (ERV) - After a normal exhalation, this is the additional air you can exhale with maximum effort. The average is about 1200 mL.
Residual Volume (RV) - This is the air that remains in your lungs after a maximal exhalation, preventing lung collapse. It averages around 1200 mL in a healthy adult.
Lung Capacities
Lung capacities are combinations of two or more lung volumes that reflect different aspects of lung function:
Total Lung Capacity (TLC) - The total amount of air the lungs can hold. It's the sum of all lung volumes (TV + IRV + ERV + RV) and averages about 6000 mL in adults.
Vital Capacity (VC) - The total amount of air that can be exhaled after a maximum inhalation. This is the sum of the tidal volume, inspiratory reserve volume, and expiratory reserve volume (TV + IRV + ERV), which is typically about 4800 mL.
Inspiratory Capacity (IC) - The total amount of air you can inhale after a normal exhalation. This is the sum of tidal volume and inspiratory reserve volume (TV + IRV).
Functional Residual Capacity (FRC) - The amount of air remaining in the lungs after a normal exhalation. It is the sum of expiratory reserve volume and residual volume (ERV + RV).
Why are these measurements important?
These volumes and capacities can help assess the health of the respiratory system, diagnose lung diseases, and determine the effect of various conditions on lung function. For example, reduced vital capacity can indicate restrictive lung disease, while changes in residual volume can suggest obstructive lung diseases.
Understanding these metrics can aid in both the diagnosis and monitoring of lung health. If you're teaching this to students, using diagrams to show how these volumes and capacities fit together in the lungs can be very helpful!

SIR........... agar hum tidal volume lay rahay hai tu is ki value residual volume say less hai tu pir residual volume ki value kaha say maintain hoti hai ? SIR...........residual volume ki air change hoti hai ya nahii bs ye store rahti hai hamaysha ?
