Microbiology is the study of microorganisms, which are tiny organisms that live around us and inside our body. An organism is a living thing that ingests and breaks down food for energy and nutrients, excretes undigested food as waste, and is capable of reproduction. You are an organism and so are dogs, cats, insects, and other creatures that you see daily.
A microorganism is simply a very, very small organism that you cannot see with your naked eye, but you sure feel its effect whenever your eyes fill with water and mucus flows like an open faucet from your nose. You call it a head cold.
Actually, you are under siege by an army of microorganisms attacking membranes inside your body. Watery eyes and a runny nose are ways that you fight microorganisms by flushing them out of your body.
