Explain the specific role of the human diaphragm in filling the lungs with air during inspiration and expelling the air during expiration.

Know how to read a respiratory graph such as below. For example, what is the increase to 6 L represent? How does this change is the airway radius changes?

Hydrogen bonding between water molecules is essential for lung expansion to occur, but also increases resistance during inspiration. Explain this contrast by describing the locations and how hydrogen bonding plays a positive and negative role in ventilation. Draw a diagram of the lung to show these opposing forces What would happen if intrapleural pressure(IPP) equaled atmospheric pressure (AtmP)? How could this happen?

Hello, please answer the following Physiology question correctly. Do not Copy/Paste from Google. Please do not give a very long answer. Thank you.  Physiology Question: "What happens to alveolar pressure and lung volume when inspiration is occurring?"
