Why do humans breathe?

Human beings need energy to be active.

  This energy, not just when we're moving or running, is our energy. 

It is used all the time, even when sleeping, to keep the creature alive.

  In other words, you can't live without creating this energy.

  When it comes to energy, it tends to be associated with already nutritious plants. 

When compared to when an object burns, it is equivalent to fuel.

  An object cannot burn with fuel alone.

  Oxygen and temperature are needed.

  The same is true of the human body, the sugar or lipids that are accumulated in the body. 

You need oxygen to burn the fuel called protein to make it energy. 

Become.

  Breathing is the act of accepting oxygen that is indispensable for maintaining this life. 

It's what's called.

  Breathing absorbs oxygen in the air, and the energy source and oxidation return in the body. 

It is the work of generating and, as a result, discharging the generated carbon dioxide out of the body.

  When you exercise hard, you breathe hard, when you lie down quietly, etc. 

The softness of the breathing is also balanced by the amount of energy the body needs. 

It must be the result of trying to secure a degree of oxygen.

  Breathing is typically a single respiration that accepts oxygen from the air into the lungs. 

It is divided into internal respiration (tissue respiration) in which cells speak.

  What we usually call breathing is this external respiration, and adult respiration rate is... 

It's about 16 times a minute at rest.

  500ml of oxygen is being absorbed at one time.

  The air that enters the nostrils is made up of different organs called non-public, throat, larynx, bronchial tubes, and so on. 

To reach the lungs through.

  So it's not until you get to the end of the lung tissue, the pulmonary emphysema. 

Gas exchange is done.

  This emphysema means that foreign substances, such as dust, can be discharged into the body by magnetically. 

Because there is no such thing, each organ up to there has the right temperature and humidity in the air. 

At the same time, the foreign body is removed in the form of phlegm, etc. due to the action of the cormor. 

An important role is given to vomit.

  And the lungs themselves are not blowing air out of their own power. 

the respiratory muscle of the diaphragm or chest, having smooth muscle or elastic gland. 

I enjoyed it because of its action.That's why they're blowing air.
