Causes of pneumonia.

Some organisms can also infect a person's lungs through the bloodstream. After entering the respiratory tract, the organism attacks a person's lung parenchyma and alveoli. The body will then produce immunity to fight the organism, which can lead to the breakdown of cytokines, inflammation, damage to the combined lung and lung system. The bacterium that most often causes this condition is Streptococcus pneumoniae, followed by Haemophilus influenzae.
