The shape of the frogs body is streamlined, with a slim body, no neck and a broad head, which allows it to propel itself through water more smoothly. Examples include the hellbender salamander and the lake titicaca water frog. Think of lungfish today, which still retain skin breathing and lung breathing. In addition, most animals with this type of respiration have lungs or gills that provide them with an alternate surface for gas exchange and supplement the cutaneous respiration.
Three ways that respiration occurs in the frog mom. Closure of the holes with the fingers restored lung inflation. Because of their thin skin, frogs must live in moist environments and secrete mucous from their skin to avoid desiccation. The skin is thin and allows for cutaneous respiration, which means that a frog is able to absorb oxygen through its skin. The skin contains many blood vessels in which oxygen can be diffused. The lining of the mouth is very moist and can be used to bring oxygen into the bloodstream by dissolving it and diffusing it into the blood capillaries, in a similar way to the skin respiration system. The skin of the frog is provided with blood capillaries. This type of respiration carried out when frog is in winter sleep or under water. The skin is composed of thin membranous tissue that is quite permeable to water and contains a large. Cutaneous respiration means that oxygen is absorbed, not breathed in. 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. It is an amphibious animal which can live both on land and in water. The metabolism of the organism depends on respiration. All frogs go through a process called metamorphosis, in which they mature from their larval.
