Frogs generally use lungs to breathe, although some species have the ability to absorb oxygen through their skin as well. Frogs have a three-chambered heart — two atria and one ventricle — and their lungs are generally simple sacs with thin walls.
While they don’t use gills, they do have specialized glands called Bidder’s organs that are located near the throat and help to maintain the frog’s electrolyte balance. The Bidder’s organs are believed to be connected to the skin and help the frog to absorb oxygen through it.
Unlike gills in fish, these organs don’t take in oxygen directly; they help to regulate it.

Do frogs breathe with lungs or gills?
Frogs use a combination of both lungs and gills to breathe. Most species of frogs use their lungs to breathe air just like humans do. However, many species of frogs also have adapted to breathe through their skin and the linings of their mouth.
This process is known as cutaneous respiration and it is used in addition to the use of the frog’s lungs.
From a young age, some frogs will have external gills called ‘labial buds’ which help to increase their oxygen supply. These labial buds, along with the skin and the mouth lining, help the frog to absorb oxygen through whatever water it is in.
This adaptation is essential for species that only thrive in aquatic environments. Frogs that live in these environments are said to be ‘obligate air breathers’ as they must take in oxygen on a regular basis in order to survive.
Frogs are extremely well adapted to their environment and they can use both their lungs and gills in order to make sure they are getting the oxygen they need. They are truly remarkable creatures!
Do frogs have gills to breathe?
No, frogs do not have gills to breathe. Frogs are amphibians, meaning they live in both aquatic (water) and terrestrial (land) environments. In order to survive on land, they have adapted a specialized respiratory system instead of gills that allows them to breathe air rather than water.
The main organ used for respiration in frogs is an organ known as the “guts cutaneous” – this unique organ is external and looks like a pair of featherless wings, located near the back of the frog near the cloaca and anus.
The gut cutaneous helps the frog to exchange oxygen and carbon dioxide directly through the skin. Frogs have the ability to absorb oxygen through their moist skin, and the organs of the back assist with this process by absorbing oxygen from the air before it ventilates out of their body.
Do amphibians have lungs or gills?
No, amphibians do not have either lungs or gills. Rather, amphibians have a unique biological structure that allows them to respire both in water and on land. They do this by utilizing three methods of respiration: cutaneous respiration, buccal respiration, and pulmocutaneous respiration.
Cutaneous respiration is when oxygen is absorbed by the amphibian’s skin, which is moist and often permeable. This is the primary method of respiration while the amphibian is underwater, and they have adapted special glands beneath their skin to keep it moist and absorb the oxygen they need.
Buccal respiration is the second method of respiration which amphibians use when they are on land. Basically, they draw air into their branching behind their nostrils and mouth, and then pass it to smaller bags in the back of the throat that deliver oxygen to the blood stream.
The last method of respiration is called pulmocutaneous respiration. This method utilizes both the lungs and the skin simultaneously, and is the one most commonly used when the amphibian is walking on land.
Air is taken in through the mouth, then passed to the lungs, where it is oxygenated, then passed out through their moist skin back into the environment.
Overall, amphibians are incredibly unique in that they do not need to rely entirely on either lungs or gills for their respiration needs, as they have adapted to absorb oxygen through their skin, as well as use their lungs and buccal.
Which animals have gills and lungs?
Some animals have both gills and lungs, a trait known as “bimodal breathing. ” These animals are able to breathe in both aquatic and terrestrial environments. Examples of animals with bimodal breathing include amphibians such as frogs and salamanders; some fish, such as tuna and cod; and some crustaceans, such as prawns and crayfish.
Additionally, certain species of sea turtles are able to switch between breathing through their lungs and gills depending on environmental conditions.
Why does tadpole have gills instead of lungs?
Tadpoles have gills instead of lungs because they are aquatic creatures that need to breathe underwater. Gills allow them to take in oxygen from the water and expel carbon dioxide, whereas lungs operate differently and require air.
Gills are slits along the side of a tadpole’s head which contain many thin filaments that absorb oxygen directly from the water in the environment. The structure of gills also allows them to filter small particles of food from the water and bring the nutrients directly into the bloodstream.
Gills also allow tadpoles to be more dispersed throughout an aquatic environment than they would otherwise be if they had lungs and needed to stay close to sources of air. Additionally, gills work better than lungs in water because they don’t require the same amount of energy to operate.
In short, tadpoles have gills instead of lungs because they are aquatic animals and require an efficient way to breathe and feed underwater.
What is a frog called when it still has gills?
A frog that still has gills is called a tadpole or a pollywog. Tadpoles are the larvae of frogs and typically look quite different from their adult forms. They breathe through gills, like fish, and have a tail and a small, rounded body.
As the tadpole matures, its tail shrinks and the frog develops lungs, which they will use to breathe air instead of gills. Eventually, the tadpole will also begin to look more like an adult frog, with four legs and a longer, narrower body.
How does a frog breathe out of water?
When a frog is out of water, it typically breathes using a technique called “buccal pumping”. This method of breathing requires the frog to fill its lungs with air by expanding its throat and drawing air in through its nostrils.
This creates a vacuum in the lungs that causes them to fill with air. The air then moves into its body and pushes out the water in its lungs. The lungs of frogs are permeable to both air and water, allowing them to breathe while in the water.
At the same time, the frog’s skin is also capable of absorbing oxygen directly from the water. This is an important secondary form of breathing for the frog while it is out of water. Since it is more active on land, the frog’s skin absorbs oxygen throughout the day and releases it into its bloodstream.
This oxygen is then used to power its muscles and keep the organs functioning. This process is also known as cutaneous respiration.
How do frogs inhale?
Frogs use a process called buccal pumping to inhale oxygen. This process uses their cheeks and other enlongated muscles of the head to pull air into the lungs. The buccal pumping process begins with the cheeks and other muscles contracting.
These contractions create a pressure difference that pulls in outside air. Once the air is inside, the frog uses its vocal sac as a valve to open the pathway from the mouth to the lungs. From there, the air travels down the windpipe and goes into the two chambers of the frog’s lungs.
The air then diffuses into the alveoli, and oxygen is absorbed into the bloodstream. As the frog exhales, the vocal sac will close, and the expelled air will be expelled through the mouth. This process can be repeated up to 200 times per minute when a frog is actively breathing.
Can frogs breathe underwater yes or no?
Yes, frogs can breathe underwater. Frogs, like most amphibians, are known as “obligate air breathers”, meaning that they need to come to the surface of the water to breathe, whereas other creatures, such as fish and turtles, possess the ability to use their gills to breathe underwater.
However, frogs still have the ability to absorb oxygen through their skin. When a frog is submerged in water, oxygen diffuses directly through its moist, permeable skin and enters into their bloodstream.
This adaptation allows frogs to remain underwater for long periods of time and can be especially beneficial when predators or other threats are present. In addition to taking in oxygen through their skin, frogs can also rely on their lungs to take in oxygen as well.
This happens when frogs come to the surface to gulp air. Consequently, frogs can survive for long periods of time underwater.
What is the breathing organ of toad?
The breathing organ of a toad is its lungs, and they work similarly to the lungs of other animals. Toads also have specialised cells in their skin that allow them to take in additional oxygen. This helps them to stay active during times when the environment has less oxygen available, such as in ponds that become stagnant during the dry season.
The lungs and the skin together provide the toad with a steady supply of oxygen. Toads also have a large vocal sac under their chin that they use to inflate and deflate when they breathe, enabling them to capture more oxygen in each breath.
This specialised air exchange helps them to stay active and survive in different kinds of habitats.
Are toads able to breathe underwater?
Yes, toads are able to breathe underwater. First, they possess a very efficient respiratory system. In particular, they absorb oxygen through their skin in addition to breathing through their lungs. This allows them to survive in oxygen-poor environments like the bottoms of shallow ponds and streams.
Second, they can slow down their heart rate and minimize their metabolic rate, which allows them to conserve oxygen. This helps them to survive in low-oxygen environments for extended periods of time.
Finally, toads possess specialized glands that produce a thick, mucoid substance that coats their skin and protects them from the depleting effects of slow-moving or stagnant water. This mucus also helps to keep the toad’s skin from drying out and gives the toad extra time to breathe air.
All of these adaptations together enable toads to make use of low-oxygen waters in order to live and thrive.
What organs does a frog use to breathe?
A frog uses its lungs and its skin to breathe. Frogs have a three-chambered heart (two atria and one ventricle), which helps to facilitate a two-way circulatory system. The circulatory system helps transport oxygen, nutrients, and hormones throughout the body.
The frog skin is thin and permeable, and is constantly exposed to the external environment, making it an important organ in respiration. The frog’s moist skin is rich in oxygen-carrying blood vessels, which take in oxygen and release carbon dioxide, resulting in gas exchange with the environment.
In addition, certain species of frogs have adapted special organs, such as the suprabranchial organ, to absorb oxygen from the water or air to additionally support their respiration.
The frog’s lungs are necessary for respiration when living in terrestrial, or land-dwelling, environments. A frog will use its powerful hind legs to jump and swim, aided by its large, flattened feet.
When a frog is submerged, air is held in its lungs which enables it to stay underwater for extended periods of time. Oxygen is then diffused from the frog’s lungs into the body. During this process, a frog will also expel carbon dioxide from their lungs, ensuring that their bodies do not become too saturated with the gas.
Which organ helps in respiration of larva of toad?
The organ that helps in respiration in the larva (or tadpole) of a toad is the spiracle. The spiracle is a small opening that is located near the head of the toad, which helps in the intake of air and the release of carbon dioxide.
The spiracle is part of the respiratory system, which includes the lungs and the gills. The spiracle works by allowing oxygen-rich water to enter the toad’s body via inhalation, while at the same time releasing carbon dioxide via exhalation.
The spiracle keeps oxygen going into and carbon dioxide out of the toad, keeping a steady rate of respiration. During their larval stage, tadpoles use their spiracles for the majority of their respiration, and eventually transition to the use of lungs for respiration once they are fully developed.
