What is called inflammation?

Can adults have stridor?
Stridor in adults is commonly caused by vocal cord paralysis; an unusual narrowing of the airway below the vocal cords called subglottic stenosis; inhaling a piece of food; or a foreign object stuck in the airway.
Does inflammation cause pneumonia?
Pneumonia is an acute inflammatory response deep in the lungs, in the alveoli. When a tissue is infected or injured, there is an inflammatory response that is, in the simplest sense, an accumulation of pus. When the deep lungs are injured or infected, pus accumulates there. Pus in the alveoli is pneumonia.
How long does lung inflammation last?
Acute inflammation happens suddenly and resolves in a few days to weeks. Chronic lung inflammation can happen gradually and take 6 weeks or longer to recover. In some cases, your immune system can attack healthy cells, which leads to chronic inflammation.
What are pulmonary infections?
Infectious lung diseases caused by the action of an infectious agent (viruses, bacteria, fungi) in assessing disease activity, spread and therapy response.
What causes emphysema?
The main cause of emphysema is long-term exposure to airborne irritants, including: Tobacco smoke. Marijuana smoke. Air pollution.
What is a bacterial lung infection?

What are the types of inflammation?
There are two types of inflammation:
- Acute inflammation: The response to sudden body damage, such as cutting your finger. To heal the cut, your body sends inflammatory cells to the injury.
- Chronic inflammation: Your body continues sending inflammatory cells even when there is no outside danger.

Bronchospasm can also cause frequent coughing without wheezing. Bronchospasm is due to irritation, inflammation, or allergic reaction of the airways.
What causes lung inflammation?
Pulmonary sarcoidosis, for instance, may cause large nodules called lung granulomas . This list covers the most common causes of lung inflammation. When airborne toxins enter the lungs, irritation results. Common irritants include: Inflammation helps repair your lungs.
What is the pattern of lung inflammation in pulmonary infections?
The pattern of lung inflammation in pulmonary infections differs depending on the infection. Generally, with a mild self-limited infection, lung inflammation should clear up as the infection resolves. Severe lung infections may cause acute respiratory distress syndrome (ARDS), a life-threatening condition in which lung function suddenly declines.
What is inflammation of the respiratory mucous membranes?
inflammation of the respiratory mucous membranes, known as rhinitis or the common cold. The term common cold is usually used when referring to symptoms of an upper respiratory tract infection.
Can inflammation of the lungs be harmful?
If the irritation is not severe, the inflammation can be short-lived and cause minimal consequences. If the irritation continues, inflammation could be more harmful. Pneumonitis is a type of inflammation that comes from being exposed to chemical irritants. It can affect the whole lung.
