What is the structure of the respiratory system?

The

respiratory system is involved in the gas exchange process necessary to survive many living things. Body function causes the accumulation of many unwanted chemicals. In addition, the body needs gases from the environment, namely oxygen to survive. Without the respiratory system, there would be no way to obtain the necessary elements and dispose of undesirable metabolic by -products. The structure of the respiratory system includes a number of related components that cooperate on successful gas exchange. All are connected to allow air to allow air to flow freely into the lungs. The structure of the respiratory system also includes bronchial tubes, lobes, pleura, cilia and mule. Of course, lungs, lung vessels, membrane, ribs and alveoli cannot be excluded as parts of the structure of the respiratory system.

On the underlining how the respiratory system structure works, it can be useful to track the air breath into and out of the lungs. Air moves due to pressure differences created by the respiratory system and the environment.When people inhale or exhale, they change the volume of their lungs, a process controlled by contraction and relaxation of the diaphragm, muscle located on the lung base. These structures are kept safely in a rib cage.

The air enters and passes through the mouth and nose and open cavities known as cavities. Then the air flows through the trachea to the bronchial tubes that are attached to the lungs. Inside the lungs are bag structures called alveoli that store this air. These structures are highly vascular and directly connected to the lung vein and artery through capillaries.

The

capillaries allow the real change of GAS between lungs and blood and are part of the vascular nature of the respiratory system. This occurs as a result of a gradient in concentration. If the lungs are rich in oxygen, for example, after inhalation, this element will move to the blood of the pulmonary artery with oxygen resistant. This blood then moves toward the heart for systemic bothh. Gradient also allows the movement of undesirable metabolic by -products such as carbon dioxide, entry into the lungs from the blood from the expenditure into the atmosphere.

There are certain situations where one or more parts of this complex system may not work properly. Symptoms in such cases differ; However, any potential respiratory disorder should be taken seriously. Due to the importance of the respiratory system structure, a professional view should be consulted if there are negative symptoms.
