Insects, like people, require oxygen to live and produce carbon dioxide as a waste product.

Amphibians breathe through lungs. Their skin has to stay wet in order for them to absorb oxygen so they secrete mucous to keep their skin moist (if they get too dry, they cannot breathe and will die). They live in the marshes, in their adult life they breathe through the lungs, they take the o 2 of the surrounding air. Most amphibians, however, are able to exchange gases with the water or air via their skin. Early in life, amphibians have gills for breathing.

Not all amphibians can breathe underwater. Some amphibians can stay for longer periods on land by breathing through lungs, while others need to go underwater after some time. Their skin has to stay wet in order for them to absorb oxygen so they secrete mucous to keep their skin moist (if they get too dry, they cannot breathe and will die). Insects do not have lungs, nor do they transport oxygen through a circulatory system in the manner that humans do.

During adulthood, most amphibians breathe through their lungs, skin, and the lining of their mouth cavities. When they metamorphose and reach their adult state they start to breathe air out of lungs. Amphibians ventilate lungs by positive pressure breathing (buccal pumping), while supplementing oxygen through cutaneous absorption. To breathe through their skin, the skin must stay moist/wet.

Breathe in a similar way to other amphibians. The early amphibians were the ancestors of all reptiles, birds, and mammals. Breathing through the skin is called cutaneous respiration. How do terrestrial reptiles breathe?

Now it is to be noted that, lung ventilation is done differently in each main reptile group. Amphibians have primitive lungs compared to reptiles, birds, or mammals. When amphibians are young, such as tadpoles, they breath using gills and spiracle. Amphibians such as frogs use more than one organ of respiration during their life.

Most amphibians breathe through lungs and their skin. Mature frogs breathe mainly with lungs and also exchange gas with the environment through the skin. With some amphibians, it appears that they can breathe underwater, when in fact they are holding their breath! Air is taken in through the nasal passage or the mouth, it then crosses the palate to the trachea, where the glottis divides the air to both bronchi, from where gas is transported to the lungs.

Reptiles breathe through the lungs. After hatching from eggs, they undergo through a larval stage which can range from just 10 days up to 20 years (for some species)! This enables them to move from aquatic to terrestrial environments during different seasons. When they metamorphose and reach their adult state they start to breathe air out of lungs.

Tadpoles breathe through the gills by moving their throat through regular rhythmic movements, known as pulsing. The lungs in amphibians are primitive compared to those of amniotes, possessing few internal septa and large alveoli, and consequently having a comparatively slow diffusion rate for oxygen entering the blood. Most of the animals known as amphibians can live on land or in water. Reptile lungs, in turn, are formed by multiple alveoli.

When amphibians are young, such as tadpoles, they breath using gills and spiracle. So when frogs are on land and they need more oxygen to jump around and to hunt for food, they breathe through their lungs to get maximum oxygen. Amphibians were the first vertebrates to appear on land. The lungs of amphibians are very poorly developed and are simple saclike structures.

Most amphibians breathe through lungs and their skin. Anura (frogs and toads) and apoda or caecilians. During their larval stage, amphibians breathe through their gills but later on develop their lungs as they move on to land. They breathe through gills while they are tadpoles.

Most adult amphibians breathe through lungs and/or through their skin. When their skin is moist, and particularly when they are in water where it is their only form of gas exchange, they breathe through their skin. Amphibians are unable to regulate their body temperature. With the exception of a few frog species that lay eggs on land, all amphibians begin life as completely aquatic larvae.

The lungs in reptiles comprise of very fine alveoli that are many. Though in some reptiles the body is adapted to their respective environmental condition like the aquatic turtles developing permeable skin but the process of respiration is not completely executed without the lungs. So the essential difference lies in their life cycle and physical appearances. The living amphibians (frogs, toads, salamanders, and caecilians) depend on aquatic respiration to a degree that varies with species, stage of development, temperature, and season.

Amphibians are vertebrates, or animals with backbones. Frogs can breathe through their skin while they are in water and when they are on land. Limbs and lungs are for adaptations of life on land and distinguish them from reptiles. While all of these species breathe using lungs, there are some species that actually breathe through their skin or gills.

The latter uses them when it goes to the surface, take the o 2 and remains floating, like other amphibians. Although most of the amphibians have lungs, they usually breathe through their skin and lining of their mouth, whereas most reptiles do not. They can also breathe through lungs, according to natural history. Amphibians typically have webbed toes and skin covered feet.

Some amphibians can hold their breath for hours. The amount of oxygen frogs can breathe through their skin is limited compared to the amount of oxygen they can breathe through their lungs. Even though most terrestrial vertebrates depend on lungs for breathing, lissamphibians also present cutaneous respiration, they breathe through their skin. That, however, is where the similarity between the insect and human respiratory systems essentially ends.

Ventilation is accomplished by buccal pumping. Amphibians are able to breathe through the entire surface of their skin or through gills, depending on which set of respiratory system they were born with. (amphibians do not have claws.) breathing: A frog breathes through its skin, the inner surface of its mouth and its lungs, depending on its circumstances.

Most amphibians have four limbs. Even if this may seem a handicap, because they must always keep their skin moist enough, in this entry we’ll see the many benefits that cutaneous respiration gives them and how in some groups, it… There are three living orders: All reptiles breathe through their lungs.

The reptiles’ lung has a much greater surface area for the exchange of gases than the lungs of amphibians. All adults are carnivorous but larvae are frequently herbivorous. Animals that breathe with their lungs can come from all over the world and live in many different types of environments, ranging from the highest of mountain tops to the lowest jungles.
