Breathing apparatus.. Provide the cells of the human body with oxygen necessary for its activities and clearance of carbon dioxide

Respiratory cells of the human body provides Oxygen Necessary for their activities, and finesse of carbon dioxide (the product of the oxidation process).
Inhale air passes through the trachea and shins (Haptih narrower) to the lungs. Each lung include much of bronchioles poetic ending a countless number of alveoli (or alveoli) very thin membranes lining being through gas exchange of capillaries that surround Palansak.And working intercostal muscles (between the ribs) And the diaphragm (Under the lungs) to run the lungs Kalker (blower mourning), pulls the air outside of them to them and then you pay at regular intervals.
Then that breathing is at the level of capillaries Respiratory importance: to breathe a big role in maintaining the continuity of activity within the body Vbaltnevs Get rid of carbon dioxide, which is harmful accumulation of the cells of the body and balance the loss of access to oxygen, which is the fuel that to Atstmr life without it because of its significant role in the continuity of vital processes within the body and oxygen supply process is a continuous process to Atnqta.And decrease oxygen leads decrease perfusion to the brain and thus show symptoms dizziness and fatigue on the patient usually either in the case of disconnection break fully, it leads to the stop of the heart muscle and thus presents human to considerable potential for loss of life unless cardiopulmonary resuscitation again at a specific time.
So Valtnevs is a necessary process to supply the heart muscleOxygen and thus pump oxygen through the blood To other members of the body and thus continue the process of life regularly within the human body..

Anatomical study of the respiratory system.. Respiratory tract. Alhvrtan Alonfitan. Bronchi. Pulmonary blood vessels. Lungs

Oxygen is obtained By process of breathing by the respiratory tract, which consists of:
1- airways: And include a series of member movement of air into the lungs and these members are
2- Alhvrtan Alonfitan: Relate with the outside Mounchrin two Mbtnan mucous membrane fringed moisturizes and heated air and Purifies the air.
3- pharynx: Which is the direct route, which extends from the back of the nasal passage, the front part of it lined with mucous membrane and Aldzoualkhalafa a common corridor for food and air together, connected from the front of the trachea is the successor of the esophagus, and passes from the pharynx through the glottis to the throat.
4- Throat: He is a member disc extends inside muscle membrane folds be vocal cords, Vthtz these ropes impact air upward from the lungs arise therefrom sounds, Valhngerh is a member sound, open throat opening oboe, and plugged when swallowing the epiglottis cartilage
5- Tracheal: It consists of cartilage tube semi-circular supports the front while the back is that it is based flexible esophagus allow the passage of food. Ibtun tracheal mucosa with cilia shaky mucosa striking dust, and particles that accompanied, and pushing it toward the mouth are so clean air inhaled.
6- bronchi: Tracheal branch some distance away from the throat to cut LIBAT smaller Kogassan tree and a Mjmuahacgerh Algosaibah.
7- Lungs: There lungs in a vacuum rib Mhattin membrane crystal visceral inside chamber wall of the ribs and sternum, spine and Daamthma diaphragm.
Both members Asvngjian resonator encompassing the tree Algosaibah that resulted from the alveoli.
Divided Goff each vesicle to a number of Convexities are alveoli air that increase capacity the inner surface of the air.
Meets alveoli to form vesicles, meets vesicles to form clumps pyramid-shaped called lobules pneumoniae. Meets lobes pulmonary and number three in the right lung and cloves only in the left lung. _ Pleura (cavity) Take all lung membrane with two sheets called the pleura, stick leaflet internal lung While stick leaflet Foreign Face of procedure of the rib cage and lungs thanks relate rib cage.
8- pulmonary vascular: Outputs the pulmonary artery from the right ventricle Vinksm into two implemented to each lung and walking adjacent to the trachea and the ramifications such ramifications until it ends in the vicinity of alveoli.
Vićkl around networks poetry heavy, resulting in a meeting capillaries branches and venous converge constitute and Reden in each lung and graduated pulmonary veins four and pour in the heart in the left atrium and including the walls of the pulmonary alveoli very thin blood shall be conditioned alveoli in direct contact with a very large surface was then pulmonary gas exchange.

Breathing functions.. Providing the body with oxygen. Put carbon dioxide. Maintain body temperature. Maintaining a balance of acid base _ or pH

The breathing following functions:
1- providing the body with oxygen from the air to the lungs, then oxidation in the lungs, thanks to molecular oxygen pressure in the alveoli and blood vessels.
2- put carbon dioxide: thanks to molecular differential pressure him in the cells, veins and alveoli.
3- to maintain a balance of acid base _ or pH.
4- to maintain body heat: as a result of combustion processes and construction and demolition within the body temperature rises internal body thereby acting in a number of ways to get rid of excess heat and these are ways and means: the nervous system, endocrine glands, lungs.

Breathing mechanism.. Sniffling. Exhale. Diaphragm. External intercostal muscles. Respiratory rate

Are renewed air inside the lungs by mechanical phenomena, the first movement of respiratory muscles that work to change the size of the rib cage during inhalation and exhalation, and overcome resistance to the airways and pulmonary pleura.
Breathing process is divided into two consecutive phases successively and continuously both inhalation and exhalation:
1- the inspiration (Inspiration): It is an active process, requiring no effort from members of the respiratory system, especially the muscles to introduce air into the lungs.
- Diaphragm: Shrinking the diaphragm muscle would drop to the bottom of the Visa rib cage vertically or longitudinally and less pressure in the lungs to become less than atmospheric pressure And rushes air inside them
- External intercostal muscles: And working to raise the sternum and pushed forward which increases the size of the rib cage from the front backwards and sideways.
2- exhaling (Expiration): a passive process or automatic does not require effort to take out the air outside the body, but come the inevitable result of the process of inspiration, but in cases forced, interfere abdominal muscles and intercostal muscles internal narrowing the rib cage, rising pressure inside the lungs expelled air them through the air passages outside the body.
Respiratory rate: Inspiratory time is longer than the time exhaling, also note a moment stopped at the end of inspiration.
The average normal breathing when a man between 13 - 18 rpm On average, 16 rpm and increase this rate in cases of heat and work and agitation, which is when more women than men at two sessions.

Gaseous exchange in the respiratory tract.. Pulmonary ventilation. The exchange of oxygen and carbon dioxide between the capillaries and cells

Form alveoli or alveoli place where gas exchange between air and blood vessels, and nature physiological and anatomical of alveoli allow this exchange that alveoli with thin wall too, and is surrounded by a network of capillaries area of about 70 m containing cells secrete a special substance called Sir Vaktant (keeps the rubber and breadth of lung), and Dermanyssus gallinae cells, tissues private, and holes all these factors working to facilitate the passage of air to and from the alveoli and go through the process of gaseous exchange in four stages:
- Gas exchange between the air conditioner and alveoli, called pulmonary ventilation.
- The exchange of oxygen and carbon dioxide between the alveoli and capillaries.
- Transfer of oxygen and carbon dioxide in the blood.
- The exchange of oxygen and carbon dioxide between the capillaries and cells.

Respiratory importance.. Continuity of activity within the body. Get rid of carbon dioxide

To breathe a big role in maintaining the continuity of activity within the body Vbaltnevs be disposed of carbon dioxide, which is accumulated harmful to the body's cells and balance lost access to oxygen, which is the fuel that does not, life goes on without him because of its significant role in the continuity of vital processes in the body and process oxygen supplementation is process continuing to Atnqta.
And decrease oxygen leads decrease perfusion to the brain and thus show symptoms dizziness and fatigue on the patient usually either in the case of disconnection break fully, it leads to the stop of the heart muscle and thus presents human to considerable potential for loss of life unless cardiopulmonary resuscitation again at a specific time.
So Valtnevs is a necessary process to supply the heart muscle with oxygen
And thus pump oxygen through the blood to other organs of the body and thus continue the process of life regularly within the human body..

Factors influencing the process of breathing.. Central nervous factors. Chemical agents

Breathing process is subject to a number of changes in the human body and these commoners == text Headline == and changes are:
1- central nervous factors:
- The hypothalamus plays a definite role in the process of breathing disorder, and can be seen during the emotion and get more rapid breathing.
- Cerebral cortex: play a role in the change process of breathing during laughing or talking or attention.
2- chemical agents:
The occurrence of any change chemical blood work on disorder centers respiratory central nervous system, and therefore affect the process of respiration, and is this effect in two ways: one directly on the nerve centers of respiratory and second indirectly by any reflex through receptors located on the walls of the arteries aorta and carotid year. The most important factors affecting breathing is pH (PH) and withBreathing Apparatus.
Respiratory cells of the human body provides oxygen necessary for its activities, and finesse of carbon dioxide (the product of the oxidation process). Inhale air passes through the trachea and shins (narrower Haptih) To the lungs. Each lung include much of bronchioles poetic ending a countless number of alveoli (or alveoli) very thin membranes lining being through gas exchange of capillaries that surround Palansak.And working intercostal muscles (between the ribs) and diaphragm (under the lungs) to run the lungs Kalker (blower mourning), pulls the air outside of them to them and then you pay at regular intervals.
Then that breathing is at the level of capillaries.

The impact of the lack of oxygen in the air of the atmosphere on respiratory.. Lack of oxygen due to anemia. Hypoxia toxic. Hypoxia cholestatic

The percentage of oxygen in the atmosphere 20.95% if dropped to less than 13%, the breathing will increase the speed and depth and so increase the amount of oxygen in the pulmonary alveoli, pushing the amount of CO2 from the alveoli decreases deep breathing for a short period before returning a deep breath because of carbon dioxide combines seconds, and so changed the depth of breathing alternately increases and decreases, and called breathing then alternating periodic breathing.
The high proportion ofCO2 in the blood occurs during respiratory cessation At the same time decrease the concentration of oxygen in the blood, centers Vttenbh breathing brain and cause increasing the depth of breathing and speed, spoke of "increased ventilation "Because of this increases the oxygen concentration drops CO2 in blood And disappears alert Centers respiratory brain goes back a second case of cessation respiratory This type of breathing is called respiration Shane Stoll, a periodic breathing alternately shows the seriousness of the condition of the person, and occurs in upland areas. If increased pressure molecular oxygen in the air of the atmosphere it will happen Tkherisat in lung tissue, so may not be that person breathes pure Oxgina for more than a few hours but it is possible to breathe a gas mixture consisting of 60% oxygen and 40% for a long time without cause health damage. 
Lack of oxygen HYPOXEMIA   Lack of oxygen is intended shortfall at the cells of the body's tissues.Reasons for the lack of oxygen:
1- lack of oxygen due to lack of oxygen entering the body. And by the decrease of molecular oxygen pressure (PO2) in the blood and occurs in the following circumstances:
- In the high altitudes where the pressure is low molecular air including oxygen.
- Inhaling corrupt air contains a small amount of oxygen at sea level.
- Rapid breathing surface.
- Diseases of the lungs.
- Congenital heart disease in which communication between the parties to the left and right heart.
2- lack of oxygen due to anemia: produced by spin hemoglobin in the blood that carries oxygen and pressure is molecular oxygen and the percentage saturation natural and occurs in all types of anemia or poisoning carbon monoxide, which binds with hemoglobin in the same way oxygen but greedily outweigh Union oxygen b 21 times, leading to the decrease in oxygen reaches the tissues.
3- lack of oxygen toxic: by poisoning oxidizing yeasts in tissue toxic substance such as cyanide where tissue itself becomes disabled and not able to take advantage of the oxygen that is compact molecular naturally and then rises in the veins to become higher than in arteries.
4- lack of oxygen stasis: It is caused by slow blood circulation through the tissues Pressure molecular oxygen in arterial blood naturally portable Kamihaloxgen normal, but the molecular pressure and quantity of oxygen in the venous blood is very low, and in the case of congestive heart failure.

The impact of carbon dioxide in the air of the atmosphere on the respiratory system.. Hyperventilation. Slowing circulatory and respiratory functions

- When the ratio of CO2 in the air inhaled normal 0.05% does not get any change in the person'sbreathing.
- If the percentage of CO2 in the breathing air to the 3% increase the depth of breathing and keep pace slow and called hyperventilation.
- If increased to about 5% increases the speed and depth of breathing.
- If increased to about 6% slowed circulatory and respiratory functions and idle Osabhma and passivity and a person has a headache, dizziness and fainting.

The role of the air passages in breathing.. Facilitate the passage of air. Ask and get the debris. Support the lungs and the thoracic wall

Not airways just channels net, but play a role in the processes of inhalation and exhalation, during inhalation manipulate and accommodate to the maximum extent to facilitate passage of air, while the time exhale less in length and diameter due to high pressure inside the rib cage to accelerate the launch air as well as you subtract and get the debris which amounts Natural 150 ml per day and increase in over-chronicler cases. Role of the pleura (Alblora) breathing: working Borktaha wall and visceral support lungs and the wall rib, which allows the lungs lying down maximum, and also allow them to move borne of two of the wall rib cage and therefore the pressure inside the gap between two pleura during exhalation be negative which equals -3 atmospheric pressure and increasingly negative during inhalation, ranging between 6-10,
In the case of forced exhalation up to +4 while forced down during inhalation to _30 atmospheric pressure.
Alveoli role in the mechanism of breathing: alveoli plays an important role, thanks to the rubber walls and muscle fibers interalveolar especially due to the impact of Sir Vaktant (Sur factant) in inflatable and shrinkage of the alveoli.
