When an antigen and its matching antibody meet in the body, the antibody binds to the antigen, marking it for destruction by the immune system. This process helps to neutralize the antigen and prevent further harm to the body.
During an antigen-antibody reaction, antibodies bind to antigens on the surface of pathogens, marking them for destruction. Macrophages recognize these marked pathogens and engulf them through a process called phagocytosis. The antibodies help enhance the efficiency of macrophages in clearing pathogens from the body.
Antigens are substances that cause an immune response in the body by identifying substances in or markers on cells

antigen
An antigen is a substance that triggers an immune response in the body, by stimulating the production of antibodies. This response helps the body to recognize and destroy harmful pathogens such as bacteria, viruses, or foreign substances.
Basically to explain this, an antigen is any type of pathogen that causes disease, while an antibody is something that combats against the antigen.
Vaccination introduces foreign antigen and the body responds by producing antibodies for that specific antigen. So overall levels of antibody may not considerably increase, but antibodies specific for that antigen will increase dramatically.
When an antibody attaches onto an antigen it destroys the antigen to help your body fight off a disease.
difference between an antibody and an antigen
Antibody
One term that is used is antigen. An antiGEN will GENerate an ANTIbody which will 'kill' the antigen.
An antigen are the germs that enter the body, and antibodies are the thing that the body produces to kill them.
antigen
Antibody are generated in our body due to attack of any foreign particle known as antigen. Antibodies are produced to provide immunity against that antigen so that if in future that pathogen or antigen again enter in our body then antibody get activate and fight with pathogen to kill it and defend us from disease.
by producing an immune response
antibody
An antigen is actually foreign or toxic to the human body. It stimulates an adaptive immune response and binds to a antibody.
