The Immune System is the defense network of the body. The immune system works with specific receptors on specialized cells - detecting foreign bodies and signaling for the immune system to destroy them.
Antibodies
The name of the system is lymphatic system.
The immune system certainly does recognize germs and other foreign bodies. The immune system will then try to fight them off.
An allergy
Food allergies occur when the immune system mounts an attack on certain proteins in certain foods. The substances in the food that trigger this immune-system response are called allergens. The immune system is a complex network of cells and molecules that help defend the body against foreign substances. When a properly functioning immune system detects a foreign substance, it responds to this threat by producing proteins called antibodies against the invaders. The antibodies will recognize and attack this foreign substance when they next encounter it. This "battle" is what causes the allergy symptoms.
the immune system
The lymphatic system is sometimes called the secondary immune system, as it helps to fight infection by filtering out foreign material such as bacteria.The primary immune system is of course the white blood cells in the blood itself, which identify and attack foreign bodies directly.
