A. The lymphocyte is the basic cell responsible for both humoral and cellular immunity.
B. The lymphocytes which enter or become processed by the thymus are called B cells.
C. Lymphocytes are found in high concentration in the lymph nodes and spleen.
D. They are found in low concentration in the bone marrow and the thymus.
E. The hemopoietic stem cells are the ultimate origin of lymphocytes.

Lymphocyte Characteristics Explained
This section details the correctness of each statement regarding lymphocytes, crucial cells in the immune system.
Evaluating Lymphocyte Statements
- Statement A: Correct
Lymphocytes are the core cells responsible for adaptive immunity. They orchestrate both humoral immunity (via B cells) and cellular immunity (via T cells). - Statement B: Incorrect
Lymphocytes that mature within the thymus become T cells, responsible for cellular immunity. Lymphocytes processed elsewhere (bone marrow) mature into B cells. - Statement C: Correct
Lymph nodes and the spleen are secondary lymphoid organs. They are densely populated with lymphocytes, serving as key sites for immune surveillance and initiating immune responses. - Statement D: Incorrect
The bone marrow is a primary lymphoid organ where B cells mature, and the thymus is where T cells mature. These organs contain significant populations of lymphocytes essential for development, thus not characterized by 'low concentration'. - Statement E: Correct
The ultimate origin of all lymphocytes lies in the hemopoietic stem cells (HSCs), which reside mainly in the bone marrow and differentiate into various blood cells, including lymphocytes.
Conclusion on Correct Statements
Statements A, C, and E accurately describe key aspects of lymphocytes.
- Statement A correctly identifies their role in both types of adaptive immunity.
- Statement C correctly places their high concentration in secondary lymphoid organs like lymph nodes and spleen.
- Statement E correctly identifies their origin from hemopoietic stem cells.
Statements B and D are incorrect based on the specific functions and locations of lymphocyte maturation and presence.
