Question

wht is humoral immunity and antigens_??​

Answer 1

Answer:

Humoral immunity is also called antibody-mediated immunity. With assistance from helper T cells, B cells will differentiate into plasma B cells that can produce antibodies against a specific antigen. The humoral immune system deals with antigens from pathogens that are freely circulating, or outside the infected cells.

$\underline \mathscr \purple{Answer \: : - }$

Humoral immunity: The B-lymphocytes produce an army of proteins in response to the pathogen. As any pathogen enters into the blood, B-lymphocytes get activated and differentiate into plasma cells that secrete a large number of antibodies in response to pathogens into our blood to fight them. Undifferentiated B-lymphocytes remain as memory cells.

Antigens: The antigens are 'molecules which when introduced into the body, stimulate the production of antibody. The word 'antigen' is a shortened form of 'antibody generating' because they stimulate the production of antibodies in response to infection. Antigens are generally large molecules. The majority of them are made of proteins or polysaccharides found on the cell walls of bacteria and other cells or on the coats of viruses. All antigens are not parts of a microorganism. Other structures like pollen grains, white of an egg, shell fish, certain fruits and vegetables, chicken, feathers of birds, blood cells from other persons or animals, drugs, chemicals, etc. can also induce the immune system to produce antibodies.
