What is Pneumonia

It is simply an infection of the Lungs that causes it to be filled with fluid or pus. It can be due to bacterial, fungal or viral causes.

The Lungs is the organ of the body that is responsible for breathing. The air (oxygen) your take in through your nose goes into the lungs, from where it goes to the rest of the body, through the blood. The air that has been used by the body (carbon dioxide) is also sent to the lungs that sends it out of your body through you nose.

When the lungs become filled with fluid or pus, it would not be able to perform this function effectively.
