Pneumonia is inflammation in your lungs caused by an infection. You have two lungs, one on each side of your chest each lung has separate sections called lobes.

Normally as you breathe air moves freely through your trachea or windpipe, then through large tubes called bronchioles, and finally into tiny sacs called alveoli.

Your Airways and alveoli are flexible and springy, when you breathe in each air sac inflates like a small balloon and when you exhale the sacs deflate.

Small blood vessels called capillaries, surround your alveoli. oxygen from the air you breathe passes into your capillaries, then carbon dioxide from your body passes out of your capillaries into your alveoli so that your lungs can get rid of it when you exhale.
