What Is Breathing Process?

We explain what breathing process? with definition and why we breathe. Also, and what happens to the cells when breathing. what is breathing process

  1. What is breathing? what is breathing process

Breathing is a biological process typical of living beings , whose objective is to keep their organism active (therefore, alive) through the exchange of carbon dioxide for oxygen.

Breathing is commonly known as the process by which we inhale air , but that is only the manifestation of the respiratory system whose process is even more complex, where the real beneficiaries are the cells of organisms, in the so-called cellular respiration. what is breathing process

In order for aerobic living beings to keep their vital functions active, they need this process consisting of oxygen consumption and the expulsion of carbon dioxide (CO2) . Depending on the species and the place where they live, they can acquire this vital element (O) through the air or water , through the pulmonary, gill, cutaneous or tracheal system.

After oxygen has fulfilled its objective within the system, what is returned to the environment , as waste, is carbon dioxide. Another element, which for other organisms such as plants is vital. so we are constantly in an exchange in the ecosystem . what is breathing process

  1. Why do we breathe? what is breathing process

Breathing allows oxygenation of blood.

As we indicated earlier, this process is essential to keep aerobic species alive and this is achieved by maintaining the body’s metabolism . what is breathing process

From the nose to the lungs and in general, all the organs that make up the respiratory system , are responsible for capturing oxygen and bringing it to the body. This will allow, for example, to oxygenate the blood or synthesize sugars for energy . All cellular tissues require oxygen to carry out their functions.

Breathing - Meditation
In exhalation, or exhalation, the air and its wastes are expelled.

The breathing process has three rhythms , which are mentioned below, but as for the biomechanics of oxygenation there are only two, inspiration and expiration.


Also known as inhalation. It is the moment where the air is brought from the outside to the inside of the organism, through the nose, nasal cavity, mouth, trachea, larynx and pharynx. What happens here is that the rib cage expands and in turn the diaphragm descends, generating enough space for the lungs to fill with air. Here the variations between the following pressures have an important function: pleural, alveolar and transpulmonary.


Instant that remains in the air.


Or also called exhalation. It is the process of expulsion of the air and its wastes (or what is not required in the body such as carbon dioxide), where the diaphragm and ribs return to their place, the muscles that retreated in inspiration relax causing The air is expelled from the lungs.
  1. What happens to the cells when we breathe?

The process by which cells and, therefore, tissues, capture oxygen carried to the body, is called tissue respiration,  where blood delivers O through the cell membrane and CO2 is returned, in addition to steam from Water.

This exchange happens when cells are surrounded by oxygenated blood . This process occurs every time it is inspired and exhales. Tissue respiration consumes about 80% of oxygen, which is where more energy is used throughout life.
