What is the respiratory zone?

The

respiratory zone is part of the airways where gas is replaced, allowing the body to trade carbon dioxide for fresh oxygen. Along with the conductive zone that attracts the air to bronchial passages, it is part of the lower airways. Disorders of this area may include inflammation, neoplasms and trauma that may disrupt the ability to engage in gas exchange. This can quickly become fatal if it is not treated. These end in small bags with bubble -called alveoli. SACs are richly supplied with deoxygenated blood from the heart. When blood moves through the lungs, a thin membrane between alveoli and blood allows fainting of carbon dioxide, while oxygen passes. Freshly filled with oxygen, blood circles back with the heart for distribution to the rest of it.

In the respiratory zone, air pressure changes as people breathe in and out to inflate and defile the lungs. Careful control of pressure is the onemediated by lubricant on the outside of the lungs, which facilitates breathing. Elasticity and lung capacity may vary according to age and level of health. As people age, their lungs can become less elastic, making breathing more difficult. The accumulation of fluid in the chest can also contribute to compression in the respiratory zone, limiting the ability to inflate the lungs with fresh air.

airways can generally be very sensitive to environmental pressures. Part of the purpose of the conductive zone is the capture of particle materials that could clog the respiratory zone and make breathing difficult. These include smoke, pollen, dust and other materials that may be present in the air. If they enter the lungs, Ceilic and AUSE inflammation may lead to scarring over time. Scars reduce the patient's ability to breathe comfortably.

patients may develop chronic diseases in the lungs due to working exposure to materials such as asbestos fiber or coal dust. These may begin with inflammation that leads to fibrosis, developmentDressing hard tissue of scars in the lungs. Chronic inflammation can also contribute to neoplasms, growth that can spread and change cancer. The respiratory zone is an area of ​​special medical interest because it is so critical of the patient's survival.
