"agglutination"-precipitation and clumping |\ |\




Opsonization-"coating" then engulfed by macrophage. - CORRECT |\ |\ |\ |\ |\ |\


ANSWERS ✔✔Please use your own words to define
|\ |\ |\ |\ |\ |\ |\ |\


"agglutination" and "opsonization" of antigen and antibody
|\ |\ |\ |\ |\ |\ |\ |\


reaction

, Stem cells differentiate into T-cell line (Thymus gland) and B-cell
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\


line (Spleen). |\




If a small soluble antigen will activate B-cell line through mono-

cloning generate lots of B-cell further become antibody and has
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\


strong memory ability. If a large complex antigen will be
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\


recognized by MHC, and bind to a denderic cell and active T-cell|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\


line, generate T-killer cell, T-helper cells, and T-memory cell, but
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\


with short memory ability. |\ |\ |\
