Explanation

Lymphocyte is the most important cell type related to the body’s immunity because it is the WBC that secretes the maximum amount of antibody proteins. Lymphocytes are formed in the bone marrow and are found in blood and lymphatic tissues. Lymphocytes are mainly of two types—B-lymphocytes and T-lymphocytes. Notably, in response to pathogens, B-lymphocytes produce a chain of proteins in human blood so that they can fight pathogens. These proteins are called antibodies (Antibodies). T-lymphocytes do not secrete antibodies themselves, but they help B-lymphocytes in producing these proteins (antibodies). These are important parts of the immune system, which protect the body from diseases caused by pathogens. (418) ## Page 17
