Name the three types of lymphocytes and identify their functions.

Verified step by step guidance

1. Identify the three main types of lymphocytes: B cells, T cells, and natural killer (NK) cells.
2. Explain that B cells are responsible for producing antibodies, which target specific antigens to neutralize pathogens.
3. Describe T cells, which include helper T cells that assist other immune cells and cytotoxic T cells that destroy infected or cancerous cells.
4. Clarify that natural killer (NK) cells provide a rapid response to virally infected cells and tumor formation by directly killing these abnormal cells.
5. Summarize the distinct roles of each lymphocyte type in the immune response to provide a comprehensive understanding of their functions.

Key Concepts

Types of Lymphocytes

Lymphocytes are a type of white blood cell essential for the immune response. The three main types are B cells, T cells, and Natural Killer (NK) cells, each with distinct roles in identifying and combating pathogens.

Function of B Cells

B cells are responsible for producing antibodies that specifically target antigens on pathogens. They play a key role in humoral immunity by neutralizing microbes and marking them for destruction.

Function of T Cells and NK Cells

T cells mediate cellular immunity by directly killing infected cells or helping other immune cells, while Natural Killer (NK) cells provide rapid responses to virus-infected and tumor cells without prior sensitization.
