What is Pneumonia? Pneumonia is inflammation from infection in your lungs. It is usually caused by bacteria or a virus, but can also be caused by a fungus, parasites or breathing something that irritates your lungs, like dust, smoke or chemicals. Your lungs have two main parts: the airways, which are also called bronchial tubes; and the sacs that hold air when you breathe, which are called alveoli. When you breathe, air moves through your airway tubes and into your air sacs. The air sacs pull oxygen from the air you breathe into your bloodstream. This oxygen moves through your bloodstream and goes everywhere in your body to keep you healthy and alive. If you have pneumonia, the air sacs become irritated and swollen, and fill with fluid. When the air sacs are full and swollen you can’t breathe easily, and oxygen cannot get into your bloodstream to be carried to the rest of your body. People with pneumonia often have a productive cough, fever with shaking chills, sharp chest pain with breathing, rapid heart rate, and in some people, particularly the elderly, confusion. Pneumonia is diagnosed by healthcare providers through physical examination, blood and sputum tests. X-rays are often used to confirm the diagnosis. 3 bronchial tubes alveoli, with fluid lungs from pneumonia
