Artist 52 [7]

Neutrophils component is deficient in a child who has a congenital immunodeficiency that impairs <u>B lymphocyte</u> function.

Neutrophils- A specific kind of white blood cell that aids in the body's defense against infection and is crucial to the immune system. White blood cells are one of the initial immune cells to react when bacteria or viruses enter the body.

B Lymphocytes- By generating antibodies, B cells are essential for pathogen-specific immunity. Immunoglobulins attached to the surface of B lymphocytes allow them to identify soluble antigens, causing them to develop into plasma cells, which can secrete immunoglobulins and produce antibodies. Primary lymphoid tissues include lymphocytes.
