Bronchitis • Bronchitis is an inflammation of the lining of the bronchial tubes. • The bronchi become infected and less air is able to flow to and from the lungs, and a heavy mucus is coughed up. • Smoking is by far the most common cause of bronchitis. • Close to 9 million Americans are diagnosed with bronchitis annually.
Influenza • It is commonly called the flu • Generally spreads from person-to-person when an infected person coughs or sneezes • Influenza can lead to severe illness if not treated quickly and effectively • Symptoms include fever, dry cough, sore throat, runny or stuffy nose, headache, muscle aches, and extreme fatigue • Children may experience problems such as nausea, vomiting, and diarrhea.
Sarcoidosis • It is also known as Sarcoid or Boeck’s disease • It is a multi-system auto-immune disease • It especially involves the lungs with resulting fibrosis but can also effect the skin, liver, spleen, eyes, bones, brain, parotid glands and other soft tissue organs. • Not contagious • It can cause lifelong ailments. • There is no cause or cure for this disease.
Air enters through the nose and the nose hairs block dust and unwanted objects The nasal passage warms and adds moisture to the air you breathe. The epiglottis is a flap that closes over the trachea during swallowing preventing choking. Esophagus • Air also enters through the mouth
The bronchi is a short tube that carries air from the trachea to each lung The diaphragm is the muscles at the bottom of the chest cavity that enables breathing Bronchioles The trachea is a tube that carries air from the nasal chamber to bronchi The lung is the main organ of this system. Gas exchange occurs here.
The alveolus is and air sac where gas exchange occurs between your blood and the air you breath Capillaries are blood vessels that surround the alveoli
Exhaling = When the diaphragm relaxes, the cavity inside your body gets smaller and your muscles squeeze your ribcage and your lungs begin to collapse as the air is pushed up and out of your body in an exhale, which reduces the air pressure in your lungs. Inhaling = Inhaling begins when the diaphragm pulls down, and lowers the internal air pressure. When the air pressure is greater outside, you suck in the air in an inhale, which expands your lungs and increases the air pressure in your lungs. Inhaling & Exhaling
