Follicular dendritic cells reside primarily in which of the following tissue/organ?
question 9 options:
a)
the bone marrow
b)
the thymus
c)
primary lymphoid tissues
d)
secondary lymphoid tissues
e)
none of these

The correct answer will be option D-secondary lymphoid tissues.

Explanation:

Follicular dendritic cells or FDCs are non-migratory dendrite cells found in the follicles of B cell areas of any secondary lymphoid organs and belong to the stromal cells of these lymphoid organs.

They help in providing immunity by shaping the responses of B in the chronic inflammatory response and auto-immune disease. These cell help in the selection of memory B cells by presenting antigens to potential memory cells to which only  B cell with B cell receptors can bind.

Thus, option D-secondary lymphoid tissues is the correct answer.

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.
