Respiratory system


Respiratory system :-
It is the device that provides human body cells with the oxygen necessary to carry out vital activities and in turn saves them from carbon dioxide, the result of the process of oxidation. The respiratory mechanism is summarized by the passage of air which is called the air of inspiration through the trachea and the two sources of this air to the lungs.
 In each lung, there are many bronchioles that branch to shivas that end with an unlimited number of endotheliums lined with thin membranes.
 Through these thin membranes exchange gases between them and blood capillaries.





Respiratory system: -
 Reduces the possibility of the body getting high temperature and the respiratory system provides the body with oxygen for the vital processes of the body and saves it from the carbon dioxide and maintains the acid balance in the body.

Respiratory components: -
throat:
It is the first component of the respiratory system, which contains the vocal cords, which receive the air and sent to the inside of the lungs.
And prevents the entry of foods to the bronchitis, because they contain excess diet that blocks the barrier of any part of the food and prevent it from passing through the bronchial tubes.
Pharynx: -

It is the second most important part of the respiratory system in order in terms of importance. It transmits food to the digestive system and enters the air into the respiratory system.
Trachea:
It consists of two parts:
 It consists of thin and delicate cartilage.
The second section consists of muscles.
The role of the trachea is divided into two functions:
Take out the sounds from the vocal cords to the lung and get rid of the bacteria that the body contains by coughing as well as expelling the sputum.
Bronchitis.
Through the process of inhalation and exhalation, the air enters the lungs.
Alveoli :-
Enhances the process of inhalation and exhalation. The vesicles also protect the delicate blood capillaries and the lungs contain 300 million vesicles.


It is necessary to care and maintain the respiratory system: -
Give the body vaccines against respiratory diseases that occur.
Breathe through the nose and stay as far as possible for breathing by mouth.
The practice of sports in general and regular and especially the sport of walking and exercises stimulated for the body and its blood.
Do not smoke and keep away from alcoholic beverages of all kinds.
Do not be exposed to cold air in the winter.
Provide the body with vaccines against various respiratory diseases.

Diseases that may affect the respiratory system: -

Asthma:
It is one of the most common diseases, a sudden contraction of the lungs, disrupting its function and increasing its severity when exposed to some stimuli such as dust, dust and smoke.

Pulmonary fibrosis:
The disease appears as scars or bruises on the bronchi.

Cystic fibrosis:
The disease is a disease of a genetic nature and increase severity when the integration of sweat and saliva with tears.

Obstructive disease: -
This disease causes the erosion of the bronchial tissue and that corroboration results in difficulty breathing.
