More recently, the only way to determine whether a person is alive, was not possible to detect or detect signs of breathing.Mirror to the mouth tray and watched if it becomes cloudy.In our time used and other features, but the lack of wind is always pointing to the rapid extinction or have already made the cessation of life.Respiratory gas exchange and is still studied by scientists to better understand the work of the respiratory system as a whole.It is very reliable, but sometimes it becomes extremely vulnerable.
This system includes airway structure respiratory this area similarly.These include the nasal cavity, larynx, trachea and bronchi.All these bodies have cartilage matrix, so they retain their shape, but inside they are lined with epithelium ciliated type.It is capable of subtle contractions to expel the small foreign bodies from the airway.
However, the main respiratory system, lungs, plays a more complex role.It is here that the exchange between the blood and air, and vice versa.Respiratory gas exchange and their main function are closely related.Easily adapted for the task structurally.
Many of us in childhood were forced to breathe only through the nose.Why is this so important?On the way through the nasal cavity of the air is more humid, but otherwise dry air could injure the lungs (remember my feelings after too intense run average prodolozhitelnosti when you have to breathe through the mouth).Furthermore, nasal antidust, otherwise, even in young adults are similar to the light dust.Therefore, those who mouth breathe constantly, often sick and coughing even against health.
The nasal cavity is divided by a partition into two parts, it is reported back to the nasopharynx special holes.The nose contains olfactory organs as well as organs, perceiving pheromones - substances that make us attractive to the opposite sex.So, respiratory and gas exchange offer and contain the components of other systems.
from the nasopharynx through the mouth air enters the larynx, for which he needs to pass through the throat.In the pharynx - a kind of intersection of the respiratory and digestive systems.There is a faithful guardian - the epiglottis that prevents food and liquids get into the respiratory tract.Just below are the vocal cords - special elastic fibers that emit a sound on the same principle as that of the violin.
larynx reaches the bottom of the neck, where it begins the next stage in the air - the trachea.Interestingly, 16 years trachea consists of cartilage, but later - ossified.Although this body is quite flexible in the process of respiration vary in length and diameter.At the end of the trachea bifurcates into two bronchi.They branched and include the lungs, and places these entries are not visible from the outside.
lungs are not fully where we are accustomed to suspect their presence - in the chest, they also issued a few centimeters above the collarbone.Their shell is divided into two parts, separated by a lubricant, so the light can be very strong and without friction (normal) to change its shape.
bronchi branch out to the bronchioles, and then turn into small bubbles - the alveoli.When
quiet breath, only 70 percent of the air reaches the lungs.Because of the difference in pressure of the oxygen passes into the blood capillaries Entangling alveoli, and carbon dioxide, in contrast, comes out of the capillaries and the alveoli is expelled.
is extremely important that you have a healthy respiratory system.And then it will be an excellent gas exchange.This will give a high efficiency and a good mood.Protect your lungs from his childhood.After all, every day they perform for us the hard work and allow cells throughout the body to get the oxygen necessary for life.
