The majority of alveoli are markedly distended with neutrophils, macrophages, fibrillar eosinophilic material (fibrin) and cellular debris.
Most pulmonary blood vessels are markedly congested with erythrocytes admixed with moderate amount of neutrophils, some of which are migrating across the vessel wall into the alveoli.
That is what I have seen in a piece of a cow's lung section under a light microscope.
There is a big battle going on in it, a war between some infectious bacteria, Pasteurella spp. that have infected the cow's lung and the cow's immune system.
The presence of the invading bacteria has triggered a great defence mechanism involving the neutrophils, the macrophages and a myriad of chemicals produced by the cow.
This is what I have been looking at, examining and appreciating for the past 15 years or more.
It is the microscopic world.
Do you wonder who orchestrate all that is going on in there?
Don't tell me that it happens by itself?
The greatest Creator of them all must have done that. It is all ALLAH's work ensuring that there is equilibrium in there, in the microscopic world!
Allah is great!
