Question

Quizplus · Accepted Answer

Lymphoid tissue is predominantly composed of reticular connective tissue, which provides a supportive framework for lymphocytes and other immune cells.

Answer: A
 Once a lymphocyte enters the lymphoid tissue, it can reside there for an extended period of time, but it may also exit and circulate through other lymphoid tissues or return to the bloodstream.

Answer: B and D are incorrect
 Lymphoid macrophages may play a role in antibody production, but they do not secrete antibodies directly into the blood. T lymphocytes do not act by ingesting foreign substances, but by recognizing and attacking cells that have been infected or transformed.
