A lung infection is when pathogens inflame the air sacs in your lungs, making it harder to breathe.
Understanding Lung Infections
Lung infections, like pneumonia, happen when harmful microorganisms enter the lungs. These infections affect the alveoli, which are tiny air sacs. When these air sacs get infected, they fill with fluid or pus. This can block oxygen from reaching your bloodstream, making it hard to breathe.
Common Causes of Lung Infections
Lung infections can stem from various pathogens:
- Bacteria: Bacteria are a very common cause.
- Viruses: Viruses, such as influenza, can also cause lung infections.
- Fungi: Fungal infections are less common, but can occur.
How Lung Infections Affect Breathing
When the alveoli become inflamed and fill with fluid or pus, this process makes it difficult for oxygen to pass into your bloodstream. This is why people with lung infections often experience:
- Shortness of breath
- Coughing
- Chest pain
- Fatigue
Pneumonia as an Example
One common example of a lung infection is pneumonia. As the reference points out, pneumonia inflames the lungs, with the alveoli filling with fluid or pus. The infection can be caused by bacteria, viruses, or fungi.
Summary
Here's a table summarizing key aspects of lung infections:
| Aspect | Description |
|---|---|
| Definition | Inflammation of the lungs, particularly the air sacs (alveoli). |
| Cause | Bacteria, viruses, or fungi. |
| Effect | Alveoli fill with fluid or pus, hindering oxygen flow into bloodstream. |
| Common Symptoms | Shortness of breath, coughing, chest pain, fatigue. |
| Example | Pneumonia is a common type of lung infection. |
In short, a lung infection involves the inflammation of the lungs, specifically the alveoli, due to various pathogens. This inflammation makes it difficult for the lungs to function effectively, especially in the transfer of oxygen.
