Short Answer:
The immune system senses foreign cells in the body and destroys them.
Long Answer:
Destroying, say, the common cold, begins when an antibody marks one common cold cell. It does this by attaching to the membrane. Another immune system cell, the nature killer cell (yes, THAT is its professional name), will kill this cell, but basically take pieces of that cell and add it to its membrane (kind of how in a video game you take the sword of the villain you just defeated as a trophy)
The natural killer cell will then wander over to another immune cell, known as the helper T-cell.
The helper T-cell
sees the pieces of the foreign cell and freaks out (this process is call antigen recognition). The T-cell
is now considered "activated" and begins to replicate and differentiate itself.
As all this is happening, and T-cell
that runs into a B-cell
(another immune cell) activates it. The B-cell
also begins to replicate and differentiate itself. One of the B-cell
types created then release antibodies that will bind to the foreign invader (the common cold, in this case) to mark it as an enemy.
The antibodies
go out and mark the invader, and natural killer cells, and cytotoxic T-cells
will go and destroy the infection and start the process over again until the invader has been eliminated.
This is still a brief summary of what occurs in a immune system response, but I hope it helps.
The purpose of the body's immune system is to protect the body from harmful pathogens such as bacteria, viruses, and other foreign invaders. It does this by recognizing and attacking these invaders to prevent illness and infection.
The immune system and the lymphatic system work together to protect the body from infection. The immune system identifies and fights off pathogens, while the lymphatic system helps circulate immune cells and remove waste products from the body. Additionally, the integumentary system, which includes the skin, acts as a physical barrier to prevent pathogens from entering the body.

The immune system and the lymphatic system work together to protect the body from pathogens. The immune system recognizes and targets pathogens, while the lymphatic system helps circulate immune cells and remove pathogens from the body. Additionally, the skin and mucous membranes act as physical barriers to prevent pathogens from entering the body.

Defensive proteins are manufactured by the immune system. These proteins help protect the body from pathogens such as bacteria and viruses. Examples include antibodies and cytokines.

The body fights diseases through the immune system, which includes specialized cells like white blood cells and antibodies. When pathogens such as bacteria or viruses enter the body, the immune system recognizes them as foreign invaders and works to eliminate them to protect the body from illness.
The function of the immune system is to protect your body from infection by pathogens and foreign invaders, or what the body perceives as invading "germs". Your immune system works to identify pathogens and sometimes other unrecognized cells, like tumor cells, that could cause disease and then to eliminate them from your system. Your body's immune system has an incredibly difficult task in this because some of these pathogens can be "sneaky": they can redesign (mutate) themselves to trick the immune system into misidentifying them as harmless cells rather than appropriately treating them as foreign invaders.
