Ventilation Explain Increases Efficiency Exchange Surfaces Gases System

Ventilation, exemplified by gills, enhances exchange efficiency by maintaining the concentration gradient for gases, facilitating continuous diffusion.

Ventilation, as in gills, improves exchange efficiency by maintaining the concentration gradient for gases, ensuring continued diffusion.

Front Explain how ventilation increases efficiency of exchange surfaces. + example
