How does a frog survive the mixing of oxygenated and deoxygenated blood?

Frogs have a three-chambered heart, consisting of two atria and one ventricle, which allows for the mixing of oxygenated and deoxygenated blood. This anatomical feature enables them to efficiently utilize the oxygen from their lungs and skin simultaneously, optimizing their respiratory process. During low activity, the mixing of blood helps to maintain oxygen delivery to tissues, while during active periods, frogs can direct more oxygen-rich blood to their muscles. Additionally, their ability to absorb oxygen through their skin aids in compensating for any inefficiencies in their circulatory system.
