Jakarta – Can you imagine breathing air during the flu? Breathing feels difficult and your respiratory system like stunted. Then, what is breathing?
Breathing is the process of exchanging gases in the body and are used to produce energy.
The process of breathing in our body is divided into three parts, namely external breathing (outer breathing), internal breathing (deep breathing), and cellular breathing (cell breathing). What is the difference?
-External respiration is the exchange of oxygen and carbon dioxide that occurs between the outside air contained in the lungs and the blood that comes from the blood capillaries.
-Internal respiration is the exchange of oxygen carried in the capillaries with carbon dioxide from the body’s cells.
-Cellular respiration is the process of entering oxygen from the body’s cells into the mitochondria to produce energy.
It is in this mitochondria that the biological oxidation process occurs. This process is the process of burning nutrients by the body with the help of oxygen to produce energy.
Process human respiratory system is an automatic process. So, even when we fall asleep, the breathing process will continue.
Because this process is greatly influenced by the autonomic nerve or nervous system unconscious.
Respiration in humans uses several means of breathing, including the nose, throat, and lungs.
The Work Process of the Human Respiratory System
Starting from the oxygen that is inhaled by our nose which then passes through the throat, into the lungs.
-Nose: In the nasal cavity there are hairs or feathers of the nose and mucus that serves as a filter or air filter so that it does not enter the lungs.
Apart from the nose, humans also breathe with their mouths. The process is that air enters the mouth through the throat (pharynx) and then into the larynx (larynx). Then the air will enter the windpipe (trachea) and end up in the lungs.
-Throat: The throat connects the breathing apparatus between the nasal cavity and the lungs. The branches from the throat are called bronchi.
Bronchi have smaller branches called bronchioles. The end of these bronchioles are the alveoli where the outside air and carbon dioxide are exchanged.
