Breathing is the process of gas exchange between living beings and the environment. In the case of human beings and animalsbreathing involves the replacement of carbon dioxide in the lungs with oxygen from the air.
Cellular respiration
In general terms, there are two types of breathing: cellular respiration and external respiration. Also known as internal respiration, it is the process of transforming chemical energy into forms of energy usable by the cell. This process is carried out by means of oxidation, degrading compounds organic to convert them into inorganic compounds. Cellular respiration, in turn, is classified into two types: anaerobic respiration and aerobic respiration. In cellular respiration, glucose degrades in a process consisting of two Stages: glycolysis and respiration.
Glycolysis occurs in the cytoplasm of cells and n or requires oxygen; It two types of anaerobic respiration of the degradation of glucose 6 carbons by a series of biochemical reactions until reaching two molecules of pyruvate 3 carbons.
The respiration occurs in the mitochondria and comprises two stages: the cycle of Krebs and the electron transport chain. It is in this last stage, the electron transport chain, where oxygen in aerobic respiration picks up electrons and forms water. If another compound such as sulfates or nitrates capture the electrons, they talk about anaerobic respiration.
It is a process of energy teo characterized by the oxidation of organic molecules by the action of oxygen, which it is taken from the air.

The end result is water and carbon dioxide. It is a type of respiration in which oxygen is dispensed with, and instead is used sulfate or nitrate, which are those that act as final acceptors of the electron transport chain It is responsible for the synthesis of ATP adenosine triphosphate, an essential nucleotide for obtaining cellular energy. It is the process of exchanging oxygen and carbon dioxide with the environment. It is classified into pulmonary, branchial, tracheal and cutaneous breathing. It is respiratikn predominant type of respiration in terrestrial vertebrates, including humans.
What are types of breathing:
In this case, oxygen is taken from the air by the nose and mouth, and will reach the trachea through the throat, through inhalation and exhalation movements. The trachea branches into two tubes called bronchial tubes that enter the lungs, and in turn branch into bronchioles. Sack-shaped structures called alveoli, which is where the exchange of oxygen for carbon dioxide takes place. Once that carbon dioxide is obtained, it is sent back to the lungs through the blood system, to be expelled into the environment. Tracheal breathing, as your The name indicates it, it occurs in the trachea, which is a structure formed by ducts or channels through which the air passes.
All insects have tracheas that pass along their body and have contact with the outside through openings called spirals. In tracheal breathing, the spirals open to take oxygen from the air, and when the insects are at rest, two types of anaerobic respiration cellular osmotic pressure allows the oxygen to dissolve with the tracheal fluid and that carbon dioxide is released to the outside. Once two types of anaerobic respiration insect leaves its resting state, the tracheal fluid is absorbed by the tissues, the breathing process is completed and the spiracles open to start the cycle. It's a t type of breathing typical of most aquatic animals and is carried out in the gills, lamellar-shaped structures that contain blood vessels. Once the water has passed through the gills, it passes directly into the bloodstream or hemolymph, a nutrient-filled liquid that is produced by invertebrate animals.
In this case, the breathing process is carried out through the epidermis.
For this to happen efficiently the skin must be kept moist, hence many animals have developed characteristics such as soft skin, with multiple folds or mucous glands to keep moisture. Anelids marine wormsechinoderms and typds have this type of breathing. The latter in some casescombine cutaneous and pulmonary breathing, such as Toads, however, it is through the skin where most of the process is carried out.]
Bravo, seems remarkable idea to me is
Your phrase is brilliant
