Organ (anatomy)

Stroma is the part of a tissue or organ with a structural or connective role.
A given organ's main tissue ( tissues being groups of cells, similar in origin, that interact to effect that organ's biological function), are namely parenchyma, and sporadic tissues, also called stroma.

Parenchyma

parenchymallung parenchymaparenchymatous
It is made up of all the parts without specific functions of the organ - for example, connective tissue, blood vessels, nerves, ducts, etc. The other part, the parenchyma, consists of the cells that perform the function of the tissue or organ. The function of connective tissue proper is to secure the parenchymal tissue, including blood vessels and nerves of the stroma, and to construct organs and spread mechanical tension to reduce localised stress.
This is in contrast to the stroma, which refers to the structural tissue of organs or of structures, namely, the connective tissues.

Stroma of iris

The stroma is a delicate interlacement of fibres.

Fibroblast

A fibroblast is a type of biological cell that synthesizes the extracellular matrix and collagen, produces the structural framework (stroma) for animal tissues, and plays a critical role in wound healing.

Connective tissue

In hematopoietic and lymphatic tissues, reticular fibers made by reticular cells provide the stroma—or structural support—for the parenchyma—or functional part—of the organ.

Extracellular matrix

Stromal tissue is primarily made of extracellular matrix containing connective tissue cells.

Ground substance

Extracellular matrix is primarily composed of ground substance - a porous, hydrated gel, made mainly from proteoglycan aggregates - and connective tissue fibers.
