How does inflammation help the immune system to fight pathogens?

Hint: There is a crucial function for the immune system: it defends the body from infectious chemicals, germs, and changes in the cells that may make you sick. Different tissues, cells, and proteins are made up of it.

Complete answer:
Inflammation is a mechanism by which the white blood cells in your body and the stuff they do protect you from infection, such as bacteria and viruses, from outside invaders.
But in certain illnesses, including arthritis, when there are no attackers to fend off, the protective system of your body the immune system causes inflammation. Your immune system behaves as if normal tissues are compromised or somehow unusual in these autoimmune diseases, causing damage.It primarily increases the temperature of the body so that no pathogens can reproduce themselves.
If there is an infection in some part of the body, a special force of large numbers of specialized cells to battle the infection that induces microbes is mobilized by our immune system.Many things happen in the body as a result of this process, such as swelling, pain, and fever, which is known as inflammation.
Inflammation occurs in the next steps—
1. The Irritation Stage: It is the first stage of inflammation in which if you have some kind of microbial infections found in some part of your body or your body, the spot will swell up so that you will feel itching in that place.
2. The Inflammation Stage: If the body part swells, it means that the immune system of the body has recognized the pathogen and is now taking action against it.The body recruits the WBC cells at this point and sends them to the inflammation site, which causes pain and burning. It also increases the temperature so that the pathogen does not replicate regularly.This entire activity produces an undesired liquid known as pus which has to be removed out to throw the pathogen out of the body.
3. The Suppuration Stage: The step of suppuration involves the discharge of the Pus created by the inflammation process. It is achieved either directly by extracting the pus or outside assistance by removing it. or By taking the pus into the stream of blood and discharging it through the anus.

Note:
When a pathogen invades body cells and reproduces, infection occurs. Usually, an infection can lead to an immune response. The infection will be removed or contained so easily if the response is swift and successful that the disease will not occur.
