Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Specialized cells located in various tissues that help initiate the immune response by recognizing, “processing”, and presenting Ag to other cells of the immune system are known as?
A
Dendritic Cells
B
Phagocytes
C
Antibodies
D
Antigens
Explanation: 

Detailed explanation-1: -B cells (sometimes called B-lymphocytes and often named on lab reports as CD19 or CD20 cells) are specialized cells of the immune system whose major function is to produce antibodies (also known as immunoglobulins or gamma-globulins). B cells develop in the bone marrow from stem cells.

Detailed explanation-2: -A dendritic cell is a type of phagocyte and a type of antigen-presenting cell (APC).

Detailed explanation-3: -Dendritic cells enter the tissues as immature phagocytes where they specialize in ingesting antigens. These antigen-presenting cells subsequently migrate into lymphoid tissue. There are two major types of lymphocyte: B lymphocytes, which mature in the bone marrow; and T lymphocytes, which mature in the thymus.
