(Respiratory System)

Basic Information

The Respiratory System consists of: The Trachea which is the tube that the air goes down when you breath in from either you mouth or nose, The lungs which take the Co2 that you breath in and turn in into air and lets all the bad things in the air out when you breath out, The trachea, also called the windpipe, filters the air that is inhaled. It branches into the bronchi, which are two tubes that carry air into the lungs. In humans, the average rate of breathing is dependent upon age. Newborns up to 6 weeks take 30 to 60 breaths per minute, while the average resting respiratory rate for adults is 12 to 20 breaths per minute. Physical exertion also has an impact on respiratory rate and healthy adults can average 45 breaths per minute during strenuous exercise.

Diseases That Can Occur in the Respiratory System

Common diagnostic tools for diagnosing respiratory disease include chest x-ray, pulmonary function test and CT scan. A bronchoscopy is performed by inserting a bronchoscope into the airways — usually through the nose or mouth — to examine for bleeding, tumors, inflammation or other abnormalities.

Diseases and conditions of the respiratory system can be caused by the inhalation of foreign bodies such as cigarette smoke, chemicals, allergens and other irritants. Not all people will develop respiratory ailments as a result of environmental factors, as genetics also play a role in the development of respiratory diseases.

Asthma causes breathing difficulties due to inflammation of bronchi and bronchioles, this causes a restriction in the airflow into the alveoli. Air pollution, tobacco smoke, factory fumes, cleaning solvents, infections, pollens, foods, cold air, exercise, chemicals and medications are some common asthma triggers.

Chronic obstructive pulmonary disease (COPD) is the intersection of three related conditions — chronic bronchitis, chronic asthma, and emphysema. It is a progressive disease that makes in increasingly difficult for sufferers to breath.

Lung cancer is often associated with smoking, but the disease can affect non-smokers as well. Like all cancers, lung cancer is caused by the uncontrolled growth of abnormal cells.

Some other ailments involving the respiratory system are respiratory infections, including tuberculosis, pneumonia and influenza.
