Question

describe in brief any three functions of antibodies

Answer 1

An  antibody is a blood protein produced in response to and counteracting a specific antigen.
The main function of antibody is to bind with antigens and inactivate them so that other bodily processes can take over, destroy, and remove the foreign substances from the body.
The binding of IgG antibodies with bacterial or viral antigens activates other immune cells that engulf and destroy the antigens.
IgM is present in the blood and is the largest of the antibodies ,It functions similarly to IgG in defending against antigens but cannot cross membranes because of its size.

Answer 2

${\fbox{\huge\sf\red{AnsWeR}}}$

Antibodies are chemical agents released by our body to fight the antigens that enter our bosh .antigens are nothing but foreign agents that enter our body.

there are few main functions of antibodies :

1) agglutination of particulate matter including bacteria and viruses 

2) neutralization of toxins released by bacteria 

3) opsonisation or coating over bacteria.

4)Antibodies act as an immunity barrier against the pathogens.
