The diaphragm is a muscle composed of fibers that separate the abdomen and the rib cage. It is called the barrier. It protects the internal organs such as the liver, stomach and intestines from the pressure of the lungs in the process of inhalation. The diaphragm is a muscle that contract and spread during the breathing process. It acts as a pump for the body that captures and simplifies the air. The diaphragm is characterized by unevenness on both sides, where the right side is the highest, due to the presence of the liver on the right side of the body.
The breathing process consists of inhalation and exhalation accompanied by the process of inhalation and exhalation contraction and expansion of the diaphragm muscle, and more accurately for the work and function of the diaphragm when the person begins the process of inhalation is the process of entering the air to the body and when the air enters the diaphragm has shrunk and And the contraction of the lower abdomen and the muscles of the ribs, ie ribs of thoracic chest moving on the outside and this gives a wide space and enough room for the expansion of the lungs any air interference through the bronchi and swells like a balloon that allows the introduction of oxygen to the human body and thus protects the internal organs of the pressure of the lungs To Members Other internal. When the exhalation process unfastens the diaphragm and helps the lung filled with air to remove air from any action to push the air and thus the size of the lung to normal to the inside of the body.
It is noteworthy that the muscle diaphragm is a muscle that confuses between being voluntary and being involuntary where the person can press and stop breathing in the case of inhalation and exhalation, and be involuntary because the process of breathing is voluntary, ie the diaphragm works without stopping and not Something that stops its work, especially in the case of sleep. When the person is asleep, the breathing process and the diaphragm continue uninterruptedly for their work. Otherwise, if the work stops, there is an imbalance in the breathing process that can lead to death. The diaphragm muscles work with the diaphragm nerve Neural signals from the brain and across the diaphragm nerve are moved to shrink This nerve extends from the spinal cord at the top of the neck and extends from the chest to the diaphragm muscle. The diaphragm nerve is met in a region called the central ligament. This ligament is the fiber group, some of which overlap the diaphragm problem. Therefore, the diaphragm is an important member of the process. Breathing works together with the lungs.
