Which one of the following contains the largest quantity of extracellular material :-

Connective tissues are characterised by a large amount of extracellular material (matrix with fibres) in which the cells are scattered.
Areolar tissue is a loose connective tissue with a semi-fluid ground substance containing collagen and elastic fibres, and cells such as fibroblasts, macrophages and mast cells. Most of its volume is extracellular material.
Epithelium has closely packed cells with very little intercellular material. Muscle and nerve tissues are mostly made of cells (fibres), with little extracellular material.
So areolar tissue contains the largest quantity of extracellular material.
