6 Examples of Your Immune System in Action

Your immune system works all the time in many different ways, but we usually don't notice it. We only really pay attention when it doesn't work well or has side effects that we can see or feel. Here are some examples:

NUMBER ONE

Cuts & infections.

  • When you get a cut, your skin acts as a barrier, but if it breaks, bacteria and viruses can enter.

  • White blood cells, a crucial part of the immune system, rush to the cut site to eliminate these invaders.

  • The immune response may lead to inflammation, a natural defense mechanism, and pus formation, which consists of dead bacteria and white blood cells.

NUMBER TWO

Mosquito bites.

  • When a mosquito bites, it injects saliva containing foreign substances into your skin.

  • The immune system recognizes these foreign substances as threats and releases chemicals to eliminate them.

  • This process causes the red, itchy bump as a visible sign of the immune system's defense.

NUMBER THREE

Breathing germs.

  • The respiratory system has mucus and tiny hair-like structures called cilia that trap and remove inhaled germs.

  • White blood cells in the respiratory system identify and destroy any germs that manage to bypass these initial defenses.

  • If a germ gets through and causes illness, the immune system works to eliminate it, leading to symptoms like coughing and sneezing.

NUMBER FOUR

Eating germs.

  • Saliva contains enzymes that start breaking down ingested germs.

  • Stomach acid further destroys many germs, preventing them from causing harm.

  • If a harmful microorganism survives these defenses, the immune system in the digestive tract kicks in to neutralize the threat, often causing symptoms like vomiting and diarrhea.

NUMBER FIVE

Immune system errors.

  • Allergies occur when the immune system overreacts to harmless substances (allergens) by releasing chemicals like histamines, leading to symptoms such as sneezing and itching.

  • In autoimmune diseases like diabetes and rheumatoid arthritis, the immune system mistakenly attacks the body's own cells. In diabetes, it targets pancreatic cells, while in rheumatoid arthritis, it affects the joints.

NUMBER SIX

Organ transplants.

  • When a new organ is transplanted, the immune system may recognize it as foreign and attempt to reject it.

  • To prevent rejection, transplant recipients often take immunosuppressive medications, which dampen the immune response.

  • The challenge lies in finding a balance to prevent rejection without compromising the overall immune function too much.
