To determine: The three types of lymphocytes and the three types of phagocytes.
Introduction: The cells that are responsible for adaptive immunity are known as lymphocytes. There are three types of lymphocytes. However, the immune cells that attack the pathogens by the process of phagocytosis are called phagocytes. They engulf the attacking pathogens and kill them.

Explanation of Solution
The three types of lymphocytes are as follows:
- B lymphocytes:
B-cell lymphocytes are the cells that have to differentiate into other types of cells called plasma cells. These plasma cells are able to destroy an antigen. The primary function of the B cells is to produce humoral immune responses, antibodies, and memory cells.
- T lymphocytes:
There are two types of T lymphocytes. These are helper T cells and cytotoxic T cells. The cytotoxic T-cells are the cells that require activation molecules such as an antigen to kill antigens. The function of the cytotoxic T cells is to generate cellular responses. However, helpers T-cells are the cells that enhance the activity of both B and cytotoxic T-cells. The function of the helper T cells is to regulate the humoral and cellular responses.
- Natural Killers (NK):
Natural killers (NK cells) are a type of lymphocytes that kill the pathogens by releasing harmful toxins and chemicals. They attack the body parts that are infected by viruses.
The three types of phagocytes are as follows:
- Macrophages:
These are the phagocyte cells that engulf the invading pathogens and kill them by the process of phagocytosis. They also help in the process of antigen presentation.
- Dendritic cells:
The dendritic cells are the phagocytes that function very similarly to the macrophages. The dendritic cells engulf the pathogens and kill them by the process of phagocytosis. They present the antigens to the T cells.
- Neutrophils:
They are the phagocytes that are involved in the process of inflammation. They destroy the microorganisms that are present in the areas that are affected by inflammation.
