Which feature characterizes a lymphatic organ?

• A. Presence of nerve endings
• B. CT capsule
• C. High blood supply
• D. Absence of lymph nodes

Answer: (B)

A key feature that characterizes lymphatic organs is the presence of a connective tissue capsule. This capsule not only provides structural support but also distinguishes lymphatic organs from other structures in the lymphatic system, such as lymphatic vessels and lymph nodes, which may not be encapsulated. The capsule helps to organize the internal architecture of the organ, facilitating the appropriate immune response by allowing for the structured arrangement of lymphocytes and other immune cells within the organ.

In contrast, while some lymphatic organs may have a high blood supply or be associated with nerve endings, these features are not universally present across all lymphatic organs. Additionally, the absence of lymph nodes does not provide a defining characteristic for lymphatic organs, as many organs contain or are associated with lymph nodes. Thus, the defining characteristic remains the presence of the connective tissue capsule.
