Answer 1

Hint: The lymphatic system, also known as the lymphoid system, is a vertebrate organ system that is part of the circulatory and immune systems. It consists of a dense network of lymph, lymphatic vessels, lymph nodes, lymphatic or lymphoid organs, and lymphoid tissues.

Complete answer:
Lymphocytes are formed and mature in primary lymphatic organs. They create an environment in which stem cells can divide and mature into B and T cells: The red bone marrow and the thymus gland are the two primary lymphatic organs. The lymphatic system, also known as the lymphoid system, is a vertebrate organ system that is part of the circulatory and immune systems. It consists of a dense network of lymph, lymphatic vessels, lymph nodes, lymphatic or lymphoid organs, and lymphoid tissues.

Primary lymphoid tissues (thymus, fetal liver, and bone marrow) promote lymphocyte development, while secondary lymphoid organs aid in lymphocyte maturation, survival, and activation. Secondary lymphoid organs are strategically distributed throughout the body, draining antigenic material from tissues and organs. The primary lymphoid organs are the bone marrow and the thymus, where immature lymphocytes develop into antigen-sensitive lymphocytes. Spleen, lymph nodes, and tonsils are secondary lymphoid organs.

Note: The spleen is a part of the digestive system. The spleen and lymph nodes are two major secondary lymphoid organs that play important roles in filtering out and destroying pathogens; Keeping the population of mature lymphocytes (white blood cells) alive so that the adaptive immune response can begin.
