Cells: Different tissues are composed of different types of cells, each with specific functions. For example, epithelial tissue is made up of epithelial cells, while connective tissue contains fibroblasts, macrophages, and other cell types. Extracellular Matrix (ECM): This non-cellular component provides structural and biochemical support to the cells. It includes collagen fibers, proteoglycans, and other molecules. Intercellular Junctions: These are specialized connections between cells that help in communication and adhesion. Examples include tight junctions, desmosomes, and gap junctions.
