Which organ is involved in cutaneous respiration?
lungs
In anurans, cutaneous respiration occurs primarily as a means of carbon dioxide exchange, with the majority of oxygen exchange occurring in the lungs. Most caudates, by comparison, take up most of their oxygen through cutaneous respiration, even in species that possess lungs.
Which skin helps in cutaneous respiration?
Answer: The skin of lissamphibians is very thin and has a high concentration of capillaries (it’s got a great number of blood vessels). As a result, it has a great capacity of diffusion of gas molecules, allowing cutaneous respiration using a countercurrent system.
What is the example of cutaneous respiration?
Cutaneous respiration in frogs and other amphibians may be the primary respiratory mode during colder temperatures. Some amphibians utilizing cutaneous respiration have extensive folds of skin to increase the rate of respiration. Examples include the hellbender salamander and the Lake Titicaca water frog.
What is the difference between respiration by diffusion and cutaneous respiration does blood participate in cutaneous respiration?
In diffusion the gases diffuse directly between the external environment and the cells. In cutaneous respiration molecular oxygen penetrates through the skin and it is collected by the blood circulation that then distributes the gas to the tissues.
What is cutaneous respiration give an example?
Some amphibians utilizing cutaneous respiration have extensive folds of skin to increase the rate of respiration. Examples include the hellbender salamander and the Lake Titicaca water frog. Cutaneous respiration in hellbenders accounts for more than 90 percent of oxygen uptake and carbon dioxide excretion.
What is cutaneous respiration give examples?
What is the difference between pulmonary respiration and cutaneous respiration?
Answer : Cutaneous respiration refers to the exchange of gases which occurs through the from the skin while pulmonary respiration refers to the exchange of gases through the lungs. Some organisms like frogs have the ability to breathe through the skin and also have lungs.
Where does cutaneous respiration occur in an organism?
Cutaneous respiration is a form of respiration in which gas exchange occurs across the skin rather than the lungs or gills. They occur in many organisms like insects, amphibians, fish, sea snakes, turtles and few mammals too.
Why is it important for frogs to have cutaneous respiration?
Although the cutaneous respiration is predominant, it is only during the colder season that it is able to sustain the life of the frogs. Cutaneous respiration requires constant moisture. When the frog is out of the water, mucus glands in the skin keep the skin moist, which helps absorb dissolved oxygen from the air.
How are gases exchanged during cutaneous respiration in reptiles?
Cutaneous exchange of gases in amphibians and reptiles. Orange bars indicate uptake of oxygen; green bars indicate excretion of carbon dioxide. Values represent the percent of total gas exchange occurring through the skin. Adapted from Kardong, 2006.
Are there any animals that have cutaneous respiration?
Even if it’s not as widespread as gills or lungs, cutaneous respiration is found in several groups of animals, such as lunged fish and some marine reptiles ( turtles and sea snakes). Yet the lissamphibians are the group that has brought their specialization in cutaneous respiration to the ultimate level.
