Tissue (biology) - Wikipedia
In biology, tissue is a cellular organizational level between cells and a complete organ.A tissue is an ensemble of similar cells and their extracellular matrix from the same origin that together carry out a specific function. Organs are then formed by the functional grouping together of multiple tissues. The English word "tissue" derives from the French word "tissue", meaning that something ...
Road Pavement Design and Maintenance
