What are to major kinds of lymphocytes?

Answer 1

Lymphocyte is a white blood cell; the two types are:

phagocytes - engulfs and digests foreign substances.

Leukocytes - releases antibodies to destroy harmful foreign substances.

side note: Antibodies break down the substance.

Answer 2

The three major types of lymphocytes are the T-cells, B-cells, and NK cells. NK cells, natural killer cells, are cells that detect other cells with tumors or otherwise altered cells and are naturally in the blood stream. B-cells secrete antibodies, which mark a pathogen for destruction and "chain" it down. T-cells come in multiple types, mainly helpers, which help other cells of the immune system develop, cytotoxic T-cells, which attempt to destroy infected cells/pathogens, and memory cells, which store "memories" of previous pathogens and how to destroy them(why a vaccine works).

Answer 3
