The fibroblasts associated with capillaries are:

 # The fibroblasts associated with capillaries are:

A. Plasma cell

B. Histiocytes

C. Lymphocytes

D. Pericytes

The correct answer is D. Pericytes.

Pericytes are cells associated with capillaries. They are located on the outer surface of capillaries and are in close proximity to endothelial cells. Pericytes play a role in supporting the structural integrity of capillaries, regulating blood flow, and contributing to angiogenesis (the formation of new blood vessels). They are not the same as fibroblasts, which are involved in the synthesis of extracellular matrix components in connective tissue.
