Light - amazing bodies by themselves, they do a great job for a person's life.This work would not be possible without the efforts that are applied at each inhalation and exhalation basic respiratory muscles.Consider the process of breathing more and outline the role of the muscles are actively involved in this process.
respirable change shape, they decrease and increase in size.The special structure of the membranes allows the lungs to move actively in all directions and change the shape of rather strongly.Therefore, a person can inhale more or less air, according to the needs or deliberately handling the process.
In general we do not think about how we breathe.This process is automatically controlled by higher centers in the medulla oblongata.However, we can consciously for some time to hold your breath, because even basic respiratory muscles, the muscles of the diaphragm, we are able to control.Although after a certain time there is a reflex inhalation or exhalation, the common man can not bring himself to stop breathing.They say that yoga can, but they pay for control of the body large enough price.
So, let's talk about the diaphragm.That's a pretty big muscles, flat, like a sheet.It forms something like a dome, and the dome that separates the abdominal cavity from the chest.When a muscle is flattened, lungs expand, the chest becomes more increases lung capacity and pressure is created, through which it is possible to tighten the air into the lungs.The main respiratory muscles provide the basic process, but it also involves supporting muscles, they become especially important in some diseases.
Pro origin diaphragm - "relative" abdominal muscles.It is found especially in mammals.In the human body, it is projected onto the region of the lower ribs.Beams of this muscle begins at the edges of the chest cavity and come to a common tendon center.
Aperture does not only breathing, she participates in the process of outflow of blood from the liver and abdominal cavity.Once this body compresses the esophagus, facilitating advancement of the food and its activity is associated with the activity of the stomach.Also, this helps to increase intra-abdominal muscle pressure, which may be important for defecation.If there are violated, the abdomen may begin to compress the chest, diaphragm keeps the balance between them all the time life.
In the process of respiration and intercostal muscles involved.External attached from the back and are directly under the skin.Their reduction pushes the rib cage expands and chest lifted.The internal intercostal muscles involved in the exhalation, if you want to do it consciously.Overall, however, exhale - just a passive process, it takes place during relaxation of the diaphragm.
Supporting considered as 3 pairs of muscles in the neck, they are involved when, for whatever reason, the main effort is not enough.An important role in breathing muscles can also play media.They are pushing the bottom edges, making it easy to change position.These muscles are very important in emphysema, when a person becomes hard to breathe in the usual way.
When a person coughs, sneezes, involved in the process, all these muscles at once, not just the main respiratory muscles, so those who coughs constantly, these muscles can hurt badly, for example, intercostal that patients sometimes take for pain in the lungs themselves.
Government human respiratory system works seven days a week, and work together with the muscles - well-organized and well-adjusted.In most cases we do not even think about that, how we breathe.Aperture - a quiet "worker".
