You know when your immune system is at work because of the symptoms you might have. Fever, swelling, and a runny nose are all examples of symptoms during an immunological response. Your immune system can respond many ways to a problem. There would be one response to a knife wound, a separate response to hay fever and pollen, and a specific response to catching a cold.

It may surprise you, but one of the most important parts of the immune system is the entire integumentary system (your skin). Your skin is usually the first defense your body has against disease. It just makes sense. There is far more chance you will get dangerous bacteria or viruses on your skin and hands than breathe those microorganisms in your lungs. You have cells and compounds on your skin that help to kill any bacteria that appear. Always remember to wash your hands; most of the microorganisms that get you sick are picked up when you touch things.

There are also genetic problems with immune systems. Something as simple as an allergic reaction happens because an individual cannot properly tolerate certain allergens. Inflammation and hay fever occur. Normal individuals can destroy those allergens, but people who are "allergic" cannot defend themselves. You could have allergies to animals, food, or plants. Some allergic reactions are so extreme they can kill.
