The lungs also known as speech expression lungs are the main organs of breathing in mammals and most other vertebrates. It is paired with pink bodies, covered with membranous sheath called the pleura. They enter the bronchi which end in alveoli. cancer de prostata Lungs surround the heart and blood vessels in the chest.
The main function of the lungs breathing cancer de prostata in oxygen from the atmosphere into the blood and exhale carbon dioxide levels in the atmosphere. cancer de prostata When they spread inhaling, exhaling while the gather. The exchange of these gases takes place in the alveoli. However, the lungs have some nerespiratorni functions.
The main function of the respiratory system is to provide oxygen, the most important source of energy for the human body keliiite. Inspired air (air that enters the process of breathing) contains oxygen, which travels through the respiratory system to the alveoli. Oxygen moves out of the alveoli and through circulation is transmitted to the body as part of the red blood cells. Oxygen in the inspired air is exchanged in the alveoli is residual by-products of human metabolism, carbon dioxide. The air we exhale contains a gas called carbon dioxide. The gas exits from alveoli during exhalation. To sum up this gas exchange would be that breathe oxygen, cancer de prostata exhale carbon dioxide.
Acute bronchitis is an acute inflammation of the lining cancer de prostata of the bronchi. The disease cancer de prostata is most common cancer de prostata in winter, especially in the period of epidemiological bumovi respiratory (breathing) and viral diseases often appear exactly as their complication. The development of acute bronchitis virus play a role and bacterial infections, allergies, toxic effects, chemical factors, physical factors (low temperature or warm air in the workplace) radiation. The most common cause of acute bronchitis is viral or viral-bacterial infection, mycoplasmas and chlamydiae. cancer de prostata In patients with acute bronchitis, along with viral infection, often observe pneumococcus, mycoplasma, Haemophilus. Acute allergic bronchitis, as a rule, observed in humans with allergic diseases that are transmitted genetically. Here, and the skin allergy. Chronic bronchitis is widespread cancer de prostata progressive destruction of the bronchial tree that appears as a result of prolonged irritation and inflammation of the airways.
These phenomena characteristic degeneration cancer de prostata of secretory (ENDOCRINE) Camera lining with qualitative and quantitative changes in bronchial secretions development of degenerative-inflammatory and sklerotski cancer de prostata (development of unifying the tissue type of scar) changes in the walls of the bronchi. Such changes in the bronchial tree is accompanied by increased secretion in violation of prochistuvachkata function of the bronchi, with periodic cough. If you are busy and small bronchi are difficult breathing and appears unproductive cough. Major factors that influence the development of chronic bronchitis cancer de prostata is smoking, air pollution, poor conditions of professional activity and climatic factors. All this supports the development of infection.
Many researchers believe that the infective factor is secondary and is added later when after a long smoking or impact of polluted air appears cough and develop conditions that lead to infection of the bronchi. Furthermore, cancer de prostata infection plays a very important role for the development of the disease.
The structure cancer de prostata of the worsening of chronic bronchitis include bacterial and viral infections. Chronic bronchitis is closely cancer de prostata associated with infections in the respiratory (breathing) organs (rhinitis, cancer de prostata sinusitis, tonsillitis, bronhoektazii parts of dilated bronchi).
Distinguish primary and secondary chronic bronchitis, obstructive cancer de prostata (by reducing the patency of the bronchi) and neopstruktivni forms. According to clinical-laboratory features of the existence and expression of inflammation vary kataralni, mucous-purulent and purulent chronic bronchitis. cancer de prostata If there is obstructive bronchitis (narrowing of the bronchi), the disease can lead to deterioration of the heart and lungs.
Acute bronchitis often occurs after a respiratory or infectious diseases along with them. Therefore, the symptomatic picture of acute bronchitis includes symptoms of viral symptoms of intoxication and tracheobronchitis. cancer de prostata Among the most characteristic symptoms are fever, increased body temperature, muscle pain, reddening of the throat, cancer de prostata appeared on pharyngitis, cough associated with inflammation of the trachea. Acute bronchitis is usually easy going. Gradually, in the course of 2-3 weeks decreases and disappears cough
