Detailed explanation-1: -Antibodies are protective proteins produced by your immune system. They attach to antigens (foreign substances)-such as bacteria, fungi, viruses and toxins-and remove them from your body.
Detailed explanation-2: -The immune system is a complex network of organs, cells and proteins that defends the body against infection, whilst protecting the body’s own cells. The immune system keeps a record of every germ (microbe) it has ever defeated so it can recognise and destroy the microbe quickly if it enters the body again.
Detailed explanation-3: -Antibodies are proteins made by the body’s natural defence system (immune system) to fight foreign substances, such as bacteria. Antibodies attach themselves to the foreign substance, allowing other immune system cells to attack and destroy the substance.
Detailed explanation-4: -1) Antibodies are secreted into the blood and mucosa, where they bind to and inactivate foreign substances such as pathogens and toxins (neutralization). 2) Antibodies activate the complement system to destroy bacterial cells by lysis (punching holes in the cell wall).
Detailed explanation-5: -Fight infectious agents. Neutralize harmful substances from the environment. Fight non-infectious diseases (i.e. cancer) Fight repeated infections more effectively. 06-Dec-2021
