Which outcome occurs when oxygen demands increase using gills?

💡 Explanation

Increased oxygen demand boosts blood flow, because this enhances the countercurrent exchange mechanism by elevating the concentration gradient, therefore boosting oxygen diffusion from water to blood, rather than diminishing diffusion caused by reduced flow.
