Explain how frog adjust respiration during different conditions
Answers
When the frog is out of the water, mucus glands in the skin keep the frog moist, which helps absorb dissolved oxygen from the air. A frog may also breathe much like a human, by taking air in through their nostrils and down into their lungs.
Though they have functional lungs, much of a frog's respiration occurs through the skin. A frog's moist skin is thin and marbled with blood vessels and capillaries close to the surface. The moisture on the skin dissolves oxygen from the air and water surrounding the frog and transmits it into the blood.
Water has dissolved oxygen which is utilised by the frog in cutaneous respiration. They have lungs to breathe air, like us but when in water they can absorb all the oxygen they need through their skins. Some frogs spend the whole winter hibernating at the bottom of ponds without breathing at all.
Tadpoles use gills, while mature frogs have three types of respiration.
1.Respiration in Tadpoles. Tadpoles have tiny external gill flaps that extract oxygen from water as it passes over them.
2.Cutaneous Respiration in Frogs.
3. Buccopharyngeal Respiration in Frogs.
4.Pulmonary Respiration in Frogs.
