Some of the animals that breathe through the most common lungs are the duck, the hen, the dog, the elephant, the frogs, the crocodiles and the turtles.
Breathing is the process by which living things take oxygen (O 2 ) And exhale carbon dioxide (CO 2 ), To keep your body active. It enters the airways, reaches the lungs and oxygenates the blood. It is exhaled by mouth in the form of CO 2.
Mammals make up one of the species capable of breathing through the lungs. They are mostly terrestrial and there are also aquatic.
Birds and reptiles also have lung breathing, as do some amphibians such as frogs and mollusks such as the snail.
Mammals can live in water and on land. Cetaceans are the animals that live in the sea and to be able to breathe, because they can not do it under the water, they must rise to the surface, take the oxygen required and go back to submerge.
Terrestrial and flying mammals, such as bats, perform the process of inhalation of O 2 And exhale CO 2 .
Amphibians have 3 types of breathing: cutaneous, buccopharyngeal and pulmonary. The latter is the simple use of the pair of lungs. The left lung is usually longer than the right lung.
Reptiles have long lungs and are internally divided into several chambers. The lining of the lungs may be covered with numerous small sacs called alveoli.
These increase the internal surface of the lungs, increasing the amount of oxygen that can be absorbed. In many snakes, only the right lung actively works. The left lung is reduced to nonfunctional sacs or completely absent.
In contrast to mammals, the lungs are rigidly incorporated into the thorax. Although the pleura is present in an embryonic stage, it then regresses. The lung is not arranged in lobes and during breathing, its volume does not change.
Bird breathing takes place in adhered air sacs that lead to the lungs. Gas exchanges do not occur in the air bags. These sacks are very thin with transparent walls. Apart from their breathing motor function, they are involved in the formation of sounds.
Different species of animals that perform lung breathing
Birds
Robin
Bird of European origin, has nostrils entering the O 2 And passes to the pharynx, then to the bronchi pass to the lungs.
The air sacs allow air to enter and exit, without any exchange within them. They allow them to have air to meet their energy requirements.
Quail
The nostrils are present at the base of the beak, protected by fine feathers that serve as a filter and prevent the ingress of foreign particles.
The o 2 Passes from the pits to the trachea, through the larynx. In the trachea, a division is presented so that the O 2 Enter the lungs, whose development is scarce.
Chicken
They take air through the nostrils, pass through the larynx and then into the trachea, dividing into two main bronchi to reach the lungs.
In the anterior air sacs enter the O 2 And passes to the later ones, emptying in the lungs.
Duck
It breathes in a similar way to the other birds, the O 2 Passes through the nostrils, 75% of it remains in the anterior sacs and 25% of the posterior sacs into the lungs.
Ostrich
Their breathing is similar to that of other non-flying birds, passing through the nostrils, larynx, trachea to the lungs, where they perform gas exchange, inhaling O 2 And expel CO 2 .
Mammals
Dog
The absorption, transport and exchange of gases is carried out. The o 2 Passes through the nasal cavities, larynx, pharynx, trachea and bronchi until reaching the lungs where the gas exchange takes place. The CO 2 Is exhaled through the intercostal and abdominal muscles.
Elephant
Through his trunk, take the O 2 Which is transported to the trachea and from there passes to the lungs, where the gas process occurs, until the CO 2 .
Horse
The o 2 Enters through the nostrils, passes through the pharynx, trachea, bronchi and later into the lungs. Gaseous exchange occurs in the bronchioles (within the bronchi).
Dolphin
It is one of the mammals that live in the water and requires going out to take the O 2 Through a hole in the top of his head called a spiracle.
From there it goes to the larynx, then to the trachea, the bronchi to the lungs. Breathing is voluntary.
Whale
It is a mammal that lives in the water, has lungs, must go to the surface to take the O 2 Through a hole in your head, submerge and go back out to take it to stay energized, similar to the dolphin. They exchange from 80% to 90% of the air contained in their lungs.
Amphibians
Frog
His breathing initially is by gills, then goes to pulmonary and cutaneous. Take advantage of the night to recover water losses during the day. The o 2 Enters through the nostrils.
Frogs
The o 2 Enters from the nostrils, the surface of the mouth ascends to bring the air to the lungs.
Subsequently the exchange of gases is done in the lower part of the mouth, the air is drawn from the lungs, passed to the mouth and passed through the nostrils again.
Salamanders
In their adult stage, they breathe through the skin and lungs. Breathe in a similar way to other amphibians.
Ajolotes
They have gills and lungs. The latter uses them when it goes to the surface, take the O 2 And remains floating, like other amphibians.
Cecilias
They live in the marshes, in their adult life they breathe through the lungs, they take the O 2 Of the surrounding air.
Reptiles
Snakes
It takes the air that reaches the trachea, the right lung, being the most widespread, is the one that performs the breathing process while the left is little used.
Crocodiles
They have a muscle that carries air to the lungs in the inhalation. The liver then helps in the process by sending CO 2 .
Caymans
The airflow goes in one direction only when it is inhaled into the lungs. This is due to the evolution of this organ that has allowed him to stay alive.
Sea turtle
It ascends to take air from the surface, which allows you to dive for more than 5 hours to depths where you can lower your heart rate and with air in your lungs, breathe and ascend.
Morrocoy
It is terrestrial. They breathe through the mouth, passing the air through the trachea, reaching the bronchi and into the lungs.
