Question

t cells achieve immunocompetence in the
multiple choice
thymus
bloodstream
spleen
bone marrow
liver

Explanation:

T cells (lymphocytes) originate in the bone marrow but mature and achieve immunocompetence in the thymus. The bloodstream is for circulation, the spleen is for filtering blood and immune responses (not T - cell maturation), bone marrow is where B cells mature and T cells originate (not mature), and the liver has other functions like metabolism, not T - cell immunocompetence development. So the correct answer is the thymus.

Answer:

A. thymus
