For fighting against pathogenic microbes in our body, immunity is the must thing that should our body need. It has cells that are specialised to kill infecting microbes and keep our body healthy. If the body's immune system is strong, it can easily fight pathogens, keeping us healthy.
Also, infections like the flu virus, mono (mononucleosis), and measles can weaken the immune system for a brief time. Your immune system can also be weakened by smoking, alcohol, and poor nutrition.
Signs of a weak immune system include frequent cold, infections, digestive problems, delayed wound healing, skin infections, fatigue, organ problem, delayed growth, a blood disorder, and autoimmune diseases. The immune system helps protect the body from harmful pathogens and other environmental risks.
HIV, which causes AIDS, is an acquired viral infection that destroys important white blood cells and weakens the immune system.
If an antigen enters the body and B-cells recognize it (either from having had the disease before or from being vaccinated against it), B-cells will produce antibodies. When antibodies attach to an antigen (think a lock–key configuration), it signals other parts of the immune system to attack and destroy the invaders.
