Detailed explanation-1: -The inner cortex contains mostly T-cells. The deep cortical, and medullary cords contain B-cells and plasma cells. Plasma cells live for 3 days, and make IgG type antibodies. This diagram of a lymph node shows the pathways that lymphocytes can take, in and out of the lymph node.
Detailed explanation-2: -Lymph nodes are not present in the central nervous system. There are three superficial regions on each side of the body where lymph nodes tend to cluster. These areas are the inguinal nodes in the groin, the axillary nodes in the armpit, and the cervical nodes in the neck.
