How do amphibians breathe?

Amphibians breathe:

Amphibians breathe through the lungs and skin, where they must keep their skin moist so that they can absorb oxygen, and secrete mucus substances to keep the skin moist, because if they have severe dehydration, they will not be able to breathe and will die.

 It is worth noting that some amphibians, such as tadpoles (babies of frogs), have gills similar to those of fish for breathing.

 Amphibians breathe through the skin In the process of skin respiration, the oxygen that is absorbed through the skin enters the blood capillaries near the surface of the skin, which would spread the oxygen to the rest of the body, and it is worth noting that sometimes more than a quarter of the oxygen consumed by these animals is absorbed directly through her skin.

 Cutaneous respiration occurs by the opposite exchange, whereby the blood flow through the skin is in the opposite direction of the absorbed oxygen or the surrounding water.

 Why is the skin of a frog wet during the gas exchange process?

 I was watching the Animal World program, and they mentioned that the skin of a frog is moist during the gas exchange process, and I want... What are the causes of shortness of breath for a pregnant woman when sleeping? I recently started feeling short of breath, especially when you go to sleep. Is this the case... What are the causes of lethargy and loss of appetite in cats with diabetes? Cats may develop diabetes, and in this case need to eat meals... The circulatory and respiratory system works with the skin to provide skin respiration, and facilitates a wide network of skin capillaries, for gas exchange, water diffusion, and ions between the animal and the environment.

 Amphibians breathe through the lungs:

 The lungs of amphibians that use them for pulmonary respiration are characterized by being simple bag-like structures, unlike the internal spongy appearance of the lungs of birds and mammals, and the respiration process of amphibians is that they receive a high rate of blood flow from the heart.

 Although the amphibian ventricle is not divided, there is a small proportion of the mixture of blood from the left and right atrial chambers within the single ventricle, as a result of which the lungs are moistened with deoxygenated blood from the systemic tissues.

 The process of pulmonary respiration in most amphibians begins when the larva reaches adulthood, when the lungs have begun to take over the respiratory function of the larval gills, as pressure is applied to the floor of the mouth, which in turn leads to the withdrawal of air into the buccal cavity through the nostrils.

 The nostrils are closed, and the floor of the mouth rises, to show positive pressure in the oral cavity, thus pushing air into the lungs through the open glottis, and exhalation is produced by contraction of the muscles of the body wall and the elastic rebound of the lungs, both of which work to remove gas from the lungs through the open glottis of the larynx.

 Can all amphibians breathe underwater?

 Some amphibians can breathe underwater, but some types may lose the ability to do so during the stages of growth and adulthood, and it is worth noting that breathing underwater is not easy for many amphibians, as it is believed.

 In some cases where amphibians are not at rest, they may need to appear on the surface of the water to breathe air, especially if they are escaping from prey, for example.

While amphibians that live in a state of rest without the need to make any effort can meet their oxygen needs under water, without the need to appear on the surface to obtain air, and it is worth noting that some types of terrestrial amphibians cannot breathe under water, despite their ability to hold their breath for hours.

 Reason for naming amphibians:

 Amphibians are distinguished by their ability to exploit both aquatic and terrestrial habitats (amphibians), as it derives from the Greek language meaning “living a double life”, although there are some types of amphibians that live on land permanently, and other types that live in water permanently. On amphibians frog, toad, salamander, salamander, and caecilian frog.

 Amphibian Characteristics:

 Amphibians have several unique traits, including the following:

 Amphibians have a dual-channel hearing system, two green rod cells in the retina to distinguish shapes, and two-part teeth. Some amphibians do not have lungs such as salamanders, and the frog Barborola calimantanensis.

The skin of amphibians contains glands that release toxins and are used to defend against predators. Most amphibians are vertebrates.

 Amphibians employ different combinations of strategies based on the gills and bronchi to complete respiration, the buccal cavity pumping mechanism that involves pushing air between the lungs, and the skin's role in respiration and maintaining water balance.
