lymphocyte
Antibody-producing blood cell
A lymphocyte is a type of white blood cell central to the immune system.
Lymphocytes include T cells, which attack infected cells directly, and B cells, which produce antibodies.
They circulate in blood and lymph, recognizing and responding to foreign substances.
The blood test showed elevated lymphocyte counts, suggesting infection.
