Where are b cells produced in the body?
lungs
keratinocytes

lymphocytes
There are two main types of lymphocytes, called B cells and T cells. Both types of lymphocytes are produced in bone marrow. They are named for the sites where they grow and mature. The B in B cells stands for bone marrow, where B cells mature. The T in T cells stands for thymus gland, where T cells mature. Both B cells and T cells must be “switched on” in order to fight a specific pathogen. Once this happens, they produce an “army” of cells that are ready to fight that particular pathogen.
