In context of the given picture ,answer the following questions :

Which among the following cells produce antibodies in response to pathogen into our blood to fight with them ?

 B-lymphocytes

The correct answer is (2)-  B-lymphocytes

The primary and secondary immune responses are carried out with the help of two special types of lymphocytes present in our blood, i.e., B-lymphocytes and T-lymphocytes. The B-lymphocytes produce an army of proteins in response to pathogens into our blood to fight with them. These proteins are called antibodies.

The cells that produce antibodies in response to pathogens in our blood are B-lymphocytes, also known as B-cells. These cells are a crucial part of the immune system and are responsible for recognizing specific antigens present on pathogens. Upon encountering antigens, B-cells differentiate into plasma cells, which are specialized cells that produce and secrete antibodies. Antibodies, also called immunoglobulins, play a vital role in neutralizing pathogens such as bacteria, viruses, and other harmful substances in the body.
