With this fact in mind, it only makes sense that we should all be doing everything possible to bolster and strengthen our immune system.
The immune system is complex, containing many interacting blood cells, proteins and chemicals. A healthy immune system contains elements that are in working together and are in balance with one another. But when the immune system is compromised, the results can be deadly.
In a compromised immune system, the components are unable to protect the body against harmful agents or mutation processes. The immune system can also be compromised when it is overworked when called upon to fight off multiple battles on several fronts.
Surgeries also depress the immune system. The greatest cause of death following a successful surgery is a secondary, or nosocomial infection (one picked up as a result of the hospital stay). With a depressed immune system, secondary infections can be deadly.
