A conscious decision can be taken on how to fill and empty the lungs. Which muscles should engage in the beathing process and in what sequence?
There are three basic groups of muscles that operate the breathing system.
1 diaphragm muscle – bottom
2 ribcage muscles – middle
3 chest muscles – top
These muscles do not attach directly to the lungs but rather to something like a bag that contains the lungs. The lungs are like two balloons connected to a Y shape splitter. By pulling the bag, vacuum is created and because of the difference in pressure the lungs inflate and deflate.
The goal is to utilize efficiently the lungs capacity and allow good oxygen absorption form the lungs, into the blood-stream.
At the top part of the lungs, there is high concentration of the exchange bubbles. The high concentration of exchange bubbles, allows relatively quick absorption of oxygen. Going lower down the lungs, the density of the exchange bubbles is reduced and the absorption of oxygen is relatively slower.
It is wise to distribute the absorption of oxygen over a larger area of the lungs and by that avoid overloading one area. Another goal is to keep as many exchange bubbles active, so that they don’t lose functionality.
When the diaphragm muscle is engaged in inflating / deflating the lungs, air gets all the way to the bottom of the lungs. This ensures better air distribution, which leads to better absorption and reduces overload.
When ribcage muscles are engaged in inflating / deflating the lungs, they pull and push the “bag” from the sides. The ribcage goes up and down, a bit like wings that open and fold.
When chest muscles are engaged in inflating / deflating the lungs, they pull and push the “bag” from the top.
Diaphragmatic breathing is also called Belly-Breathing, Abdomen-Breathing or Stomach-Breathing
An efficient way of breathing is a “Full 3 stage Yogic breathing”, where all 3 sections of the lungs are utilized to the fullest. First bringing air to the lower part of the lungs, where there is slower absorption and then inflating the middle and upper part of the lungs. Deflating in reverse order.
