Pneumonia, an infection of the lungs, occurs when an illness causes an increase in mucus in the airways. The mucus allows viruses and bacteria to multiply, resulting in the infection. The American Academy of Family Physicians reports that viruses...
During surgical anesthesia, respiratory reflexes such as gag reflexes that normally prevent vomited food or gastric juices from entering the lungs are suppressed. Food, stomach juices, blood or saliva can enter the trachea, the tube that leads to...
The double-layer membrane surrounding the lungs is called the pleura, and also covers the inner chest wall. It keeps the chest cavity airtight, however, if air enters the space between the two layers of the pleura, a collapsed lung or pneumothorax...

Bronchopneumonia, also known as bronchial pneumonia, is a disease resulting in an acute inflammation of the small bronchial tube walls. If left untreated, bronchopneumonia can cause lung abscess, emphysema, jaundice and heart failure. Exercises...
The lungs are a pair of organs in the chest responsible for respiration, a process that involves breathing in air and adding fresh oxygen to the blood, which then carries the oxygen to the cells. Many factors and conditions can alter how the lungs...
Cavities in the lungs are formed by inflammation of lung tissue leading to the development of an abscess. When the abscess ruptures, the contents are expectorated, leaving behind an air- and fluid-filled cavity. Chest X-rays and computer...
Lung infections are one of the most common infections that patients acquire, according to the Washington Manual of Surgery. Lung infections often start with viral disease such as influenza or the common cold. Respiratory tract viruses are common...

Methicillin-resistant Staphylococcus aureus, or MRSA, is a strain of the Staphylococcus aureus bacteria. It is resistant to several antibiotics usually used to treat Staphylococcus--or staph--infections. MRSA infections increased from 2 percent of...
Klebsiella pneumoniae is a ubiquitous bacterium normally found in the mouth, throat, skin and especially the intestines of most healthy people. Klebsiella can become a problem and cause serious infections in those with compromised or weakened...
Pathogenic bacteria cause disease in humans. Many different types of bacteria prove harmful to humans, causing infections that range from mild to potentially life threatening. In most cases, pathogenic bacteria can invade different areas of the...
Methicillin-resistant Staphylococcus aureus, also called MRSA or antibiotic staff infection, may cause a variety of symptoms when pneumonia--a secondary infection--develops. According to the Centers for Disease Control and Prevention, staph...
A fungus is a type of microorganism that can infiltrate the lungs and create severe respiratory problems such as difficulty breathing, a fever and a cough. Sometimes, individuals are more susceptible to fungal lung infections if they live in a...
