Immunity.
Yes. Antibodies are made in response to pathogens. The antibodies are made by WBCs. These antibodies are a "match" to the pathogen. The next time the body is attacked by this pathogen, the antibody response will be much faster and a person will recover much sooner.
titer
Active immunity can be acquired through natural exposure to an infectious agent, which triggers the body's immune response to produce antibodies. It can also be acquired through vaccination, where the immune system is exposed to a weakened or inactivated form of the pathogen, leading to the production of antibodies without causing illness.
The blood cells detect the pathogen The pathogens release toxins The blood cells make antibodies to fit the toxins ( they have to be a specific shape) The antibodies stick the bacteria together ready to be engulfed by he white blood cells The White blood cells remember the antibodies needed for that pathogen so they can make antibodies quicker next time the pathogen invades
Antibodies are formed as the defence against antigen or pathogen which is consider as a foreign particle by body against whcih body immune system acts. Antibodies are formed my activated B cells called plasma cell and are made of glycoproteins
Antigens
Antigen. An antigen is a small piece of a pathogen, such as a virus or bacteria, that triggers the immune system to produce antibodies to fight off the infection. This immune response helps protect the body from further exposure to the pathogen in the future.
An antigen is a substance that produces an immune response in the body, typically by binding to specific antibodies or activating immune cells. This immune response is essential for recognizing and eliminating foreign substances such as pathogens.
c. a pathogen makes more than one antigen. Pathogens typically have multiple epitopes that can be recognized by antibodies, but they do not make more than one antigen. Each pathogen produces specific antigens that can trigger an immune response.
This type of reponse is the adaptive response which develops over the life span and "learns" and "remembers". This makes antibodies in response to antigens.
Positive antibodies indicate that the immune system has produced antibodies in response to a specific infection or vaccination. These antibodies help protect the body against future encounters with the same pathogen by recognizing and neutralizing it.
Active immunity can be gained through natural infection, where the body produces antibodies in response to exposure to a pathogen. Alternatively, it can be acquired through vaccination, which introduces a harmless form of the pathogen or its components, prompting the immune system to generate a protective response without causing the disease.
