Breathing and the Muscles

The process of breathing is essential to live, because it is responsible for providing oxygen to each of the parts of our body. And in this vital process plays a key role the respiratory muscles, often marginalized in the physiology of respiration but in reality, have a leading role. For this reason then we devote a few lines to the breathing muscles.
Given that the proper contraction of these muscles depends on the proper exchange of gases between the internal environment of the organism and the outside, we must take into account what are the breathing muscles, and take care of their functionality to avoid the development of symptoms associated with a poor oxygenation of the tissues, i.e. to a failure in the breathing.
Among the respiratory muscles we found those inspiratory muscles such as the diaphragm and the intercostal external as well as the Serratos, escalenos, pectoral, and subclavian lymphatic spinal. On the other hand, we find the expiratory muscles such as the internal intercostal and abdominal wall muscles such as the transverse diameter of the abdomen, the oblique, pyramidal and the rectus abdominis.

During the air inlet or inspiration, the diaphragm contracts by scrolling down, allowing the rib cage will widen and gulp air to the lungs. The external intercostal at the same time raise the ribs and sternum allowing the diameter of the rib cage will increase. This increase in the volume chest creates a negative pressure that causes the air to the lungs.
During expiration or air output is relax the inspiratory muscles and reduces the volume of the rib cage by creating a positive pressure that draws the air from the lungs to the external environment. In expiration the voluntary muscles of the abdominal wall are collapsed by pushing the diaphragm upward and allowing air output, while the internal intercostal pushed down the ribs.
At rest, the human body only needs the diaphragm and intercostal breathing but by situations such as the cough, physical exercise and other, can be used to optimize the process of breathing muscles to throwing hand as the abdominals, the pectoral, the serratus, escalenos and others.
Then, it is important to know that the training of these muscles to its participation in the process of breathing can be of great importance, collaborating with a efficient ventilation that allows us to pay more at the time for us to strive physically, for example.
The training of respiratory muscles is possible and are used to optimize amplaiamente pulmonary ventilation, especially in those who need to rehabilitate itself because of a disease.
