For my initial idea for this project, having my target audience in mind of a young child audience. I thought of using the plasma cells within the body as a police department, HBPD (Human Body Plasma Department) These cells with fight off bacteria trying to enter the body. They will do this by having the antibodies as their ammunition which they will fire at the bacteria. They will need to find the right ' ammunition' to fit the shape of the bacteria (as antibodies work). Once they capture the bacteria they will send in the White blood cells to destroy the bacteria.
How the Body Fights Bacteria
Your body uses white blood cells to fight off the bacteria and viruses that invade your body and make you sick. In the gif below you can see a white blood cell called a neutrophil chase down a Staphylococcus aureus bacterium. The circular cells that the white blood cell is moving through are red blood cells.
Your body is constantly covered (inside and out) by bacteria. Some are good for you, some are harmless and some can make you sick. Staphylococcus aureus is frequently found on our skin and respiratory tract. It doesn't always cause disease, but can infect the skin or lungs. There are more bacteria in and on your body than there are people on the Earth. Think on that one for a few minutes.
The white blood cell is attracted to the bacteria because proteins called antibodies have marked the bacteria for destruction. These antibodies are specific for disease-causing bacteria and viruses. When the white blood cell catches the bacteria it goes about "eating" it in a process called phagocytosis.
