The immune system and inflammation are linked, with the immune system directing cells to areas of the body to fight harmful stimuli. Inflammation is a necessary response to cleanse the body, but can also be a problem in autoimmune diseases. Vaccines work by training the immune system to recognize pathogens.
The immune system and inflammation are interrelated as the actions of the immune system cause the inflammatory properties recognized throughout the body. Inflammation can be due to a number of things, but basically it’s an overabundance of cells or fluid in a particular region. This dense collection of matter causes an area of the body to feel larger than usual, and sometimes discoloration or tenderness is also present. The immune system is usually the commander telling cells and other matter to go to a certain area.
People go about their daily lives without stopping to think about the environment in which they live. There are a number of biologically harmful elements that can potentially harm or kill an unprotected human being. Thankfully, a healthy immune system works to protect the body from disease-causing bacteria, viruses, and other antigens. Sometimes, when one of these harmful stimuli is detected, the immune system and inflammation kick in to try and rid the body of these things.
Inflammation is part of the response that attempts to cleanse the body of whatever is causing harm. The immune system has special cells that attack bacteria and viruses. They can also recognize certain disease-causing beings, known as pathogens, and use their experience to be better suited for the next battle.
This recognition system is why vaccines work. Vaccines are actually dead or weakened viruses that are injected into the body so that the immune system can get used to the pathogen. However, this doesn’t work for all viruses, because some types can evolve to avoid recognition. An example is the HIV virus which causes AIDS.
The immune system and inflammation can work in the short or long term. Brief attacks are known as acute responses, while chronic inflammation is usually the result of long-term illness. The immune system and inflammation can also be a problem with autoimmune diseases. An autoimmune disease is an irregularity in which the immune system attacks particular, usually healthy, areas of the body for reasons that are not fully understood. An example of this type of disease would be rheumatoid arthritis.
Immune system function and inflammation help fight off disease. Humans and other creatures are unlikely to survive without them. While inflammation may sometimes seem problematic, it’s actually necessary.
