Quizplus · Accepted Answer

Lymphoid follicles are the masses of lymphoid tissue found within a lymph node, consisting predominantly of B lymphocytes. They are also called lymphatic nodules or lymphoid nodules.

Answer: D
 The white pulp of the spleen is also made up of masses of lymphoid tissue (primarily lymphocytes) that are involved in immune function.

Option A refers to the connective tissue strands that extend throughout the lymph node, providing structural support. Option B refers to the indented region of the lymph node where blood vessels enter and exit. Option E refers to the space beneath the capsule of the lymph node where lymph enters. While all of these structures are present in a lymph node, they do not specifically refer to masses of lymphoid tissue.
