This type of epithelium serves a protective function. In adult frog, due to its amphibian life, respiration occurs through skin (cutaneous respiration), lining of the bucco-pharyngeal cavity (buccal respiration) and the lungs (pulmonary respiration). Vocal sac, the sound -resonating throat pouch of male frogs and toads (amphibians of the order Anura). The skin contained mucus glands to keep it moist, and it also had pigment cells to regulate its color.
