Final answer:

Increasing alveolar area enhances gas exchange efficiency in the lungs. Oxygen flows into the bloodstream, and carbon dioxide flows out during gas exchange. Ventilation brings fresh air to the alveoli where gas exchange occurs.


Explanation:

Gas Exchange in the Human Respiratory System

When the alveolar area of the lung is increased, it enhances the surface area available for gas exchange. This increase in surface area allows for more efficient diffusion of gases, specifically oxygen entering the bloodstream and carbon dioxide exiting the body.

Ventilation vs. Gas Exchange

Ventilation is the process of moving air in and out of the lungs, while gas exchange refers to the diffusion of gases between the alveoli and the bloodstream. Ventilation facilitates the exchange process by ensuring fresh air reaches the alveoli where gas exchange occurs.

Oxygen flows from the alveoli into the bloodstream, while carbon dioxide flows from the bloodstream into the alveoli during gas exchange in the lungs.
