human respiratory physiology - one of the basic processes of life
breath - one of the basic functions of life support in a living being.As with all other functions, breathing is not the primary or secondary process - this is one of the elements of coordinated, coherent work of all systems and organs.
Physiology process can be both normal and pathological.In order to understand more about the breath and be aware of the norms and deviations should immediately consider itself the breathing process.
Anatomy and physiology of the respiratory system in all living creatures arranged in different ways, but is subject to a single natural principle - the normal livelihood of the body.The normal physiology of human breathing involves the implementation process through the nasal cavity.Roth used for breathing only when the nose becomes a kind of problem.For example, when a cold adult mouth breathing, since nasal breathing is difficult.In childhood, when breathing through the mouth, doctors often suspect overgrown adenoids that block the passage of air through the nasal cavity.
Nasal breathing is very important for a person, which is why even an early age parents teach children to breathe through the nose to the habit of "enough air mouth" does not lead to diseases of the throat.Physiology of breathing so arranged that passes through the nose, air flows down the airway has warmed, not so cold.This is due to the fact that the bow is a dense network of blood vessels which are heated by passing air through the nasal cavity.In addition to the warming function, nose perfectly cleans the air, delaying the tiniest speck of dust falling from the air stream.Man is important to know that the day the nose too in some way affected by such pollution of air, so the daily (morning) readjustment of the nasal cavity is necessary.
From winding nasopharynx air is lowered into the larynx and trachea.The trachea is in turn divided into bronchi which run to the right side to the right lung and the left side of the left lung.Sami bronchi resemble branched tree that is divided into the bronchioles and alveoli at the end of ends (pulmonary bubbles).This is where the direct exchange of oxygen to tissues and transport it with blood through the body.To ensure maximum safety of the breathing process in terms of dust and bronchi, trachea and fitted inside the ciliated epithelium which is directed towards the oral cavity.In this manner formed mucus that coats the particles of dust, is output to the epithelium of the oral cavity.When you cough or sneeze the human body secretes mucus particles that cleanse the respiratory system - it assumes the physiology of respiration, so the light is not viscous sputum, there is no reason for concern.Much worse, if the sputum is difficult moves, it has a yellowish-green color, or admixture of blood - this pattern may indicate a serious defeat of the respiratory system.
alveoli in their structure is very peculiar - nature is completely subordinated to their respiratory physiology.Alveolar walls are thin - only one layer of cells pass freely oxygen and carbon dioxide.A special role in the breathing process is the surfactant - a special substance that covers the walls of the alveoli.Thanks to him, the walls of the alveoli are not prone to atelectasis - wears off.That is why it is very important that children born full-term - in their alveolar surfactant enough that kids can breathe independently.
Breathing Physiology includes not only the work of agencies related to the respiratory system.Respiratory process involves the bones (ribs slightly lifted), muscle (directly actuates the edges), the diaphragm (special muscle that pushes the abdominal organs and respiratory acts increases the volume of the chest cavity).Normal physiology of breathing fully provides the body with the necessary oxygen for his life and displays the "waste" gas - these are complex processes occurring in the human body.
