Hi there,
The heart of the frog has three chambers, one ventricle and two atria. ... Both atria then empty into the single ventricle. Blood from the ventricle thus enters either the pulmonary or body circulation. Because there is only a single ventricle there is some mixing of oxygenated and deoxygenated blood.

Explanation:
In frog, arterial arches divide into pulmonary and cutaneous arteries, and transport venous blood through pulmocutaneous arteries to the respiratory surfaces of the skin. The frog carries out respiratory exchange through moist skin. The blood returned from the skin through pulmocutaneous vein is rich in oxygen content.
