The Respiratory System

The human body requires many things to function. One of the most important requirements is oxygen. Oxygen is used by the entire body to make energy. The Respiratory System collects and filters the air we breath to get that precious oxygen. The respiratory(breathing) process begins when you inhale and air is taken in through the mouth and/or nose. The air flows into the pharynx(throat) and enters the trachea(windpipe). The air then flows into one of two bronchi, left bronchus and right bronchus. The left bronchus transports air to the left lung and the right bronchus transports oxygen to the left lung. The bronchi split into smaller bronchi, which split into even smaller tubes called bronchioles. The part of the Respiratory System described, nose to bronchioles, is called the respiratory tract. At the bottom of the bronchioles air sacs called alveoli. This is where oxygen enters the blood and carbon dioxide leaves it. When you exhale, Carbon dioxide leaves the Respiratory system through the mouth and/or nose.
One such disease is Interstitial Lung Disease. Interstitial Lung Disease causes scarring of the lungs. This can cause coughing, fatigue/inability to exercise, shortness/faster breath, and in some cases deformity of nails and weight lose. Interstitial Lung Disease can be caused by exposure to hazardous material or an autoimmune disease.
Another disease harmful to the Respiratory System is Bronchitis. Bronchitis is the inflammation of the lining of bronchial tubes. Some symptoms of Bronchitis are chronic/dry/phlegm cough, fatigue or malaise, runny nose or postnasal drip. Some other common symptoms are chest tightness, headache, shortness of breath, sleeping difficulty, or sore
