respiration in frogs is as follows:

1)most anphibians such as frogs can live in water and on land. therefore, they mist have respiratory surfaces that may enable them to live on land and in water.

2)adult frogs breathe through the lungs,skin and mucus lining of the mouth.

3)their skin is always moist,permeable and is supplied with abundant blood capillaries.

4)there are also mucuos glands in the skin to keep the skin moist.

5)amphibians have lungs that can be used when necessary. a)the lungs of a frog are simple elastic sacs with abundant blood capillaries b)the lungs have numerous small ridges that increase the respiratory surface. c)cells lining the lungs are thin abd moist to allowgases to diffuse efficiently and rapidly.

6)there are no ribs or diaphragm to support breathing

7) the breathing mechanism of frogs are as follows a)they inhale by opening the nostrils, closing the glottis and lowering the buccal pharyngeal cavity. b)the enlargement of the buccal pharyngeal cavity creates a partial vaccum and air enters through the nostrils. c)when the nostrils are closed, the glottis are opened and the floor of the mouth is raised, and the air is pushed into the lungs. d)they exhale by pushing the air out through the nostrils when the abdominal muscle contracts. this mechanism is called POSITIVE PRESSURE BREATHING.
