The extracellular matrix of animal cells holds cells together to form a tissue and allow tissues to communicate with each other. In some cases, the ECM accounts for more of the organism's bulk than its cells. Elastic fibers in the ECM allow tissues such as skin, the lungs, and blood vessels to withstand repeated stretching and considerable deformation and to return to a relaxed state. The extracellular matrix (ECM) is a three-dimensional network of extracellular macromolecules. It contains high quantities of water, several types of cells, and a fibrous extracellular matrix.The connective tissue of an organ is usually referred to as the stroma.This tissue type can have very different structures according to the proportions of its components.
