Give any two breathing systems of a toad?

1. Cutaneous respiration: Toads have a thin, moist skin that allows for gas exchange to occur through diffusion. Oxygen is absorbed through the skin while carbon dioxide is released.

2. Pulmonary respiration: Toads also have lungs that are used for breathing. Air is drawn into the lungs through the nostrils and oxygen is exchanged with carbon dioxide in the blood.
