Document Summary
Tissue a group of similar cells that work together to perform a specific structural or physiological role in an organ. The four primary tissues differ from one another, as follows: Relative amount of space occupied by cells versus matrix. Clear gel called ground substance, tissue fluid, extracellular fluid (ecf), interstitial fluid, or tissue gel characteristics of epithelial tissue. Consists of a flat sheet of closely adhering cells. Upper surface usually exposed to the environment or an internal space in the body. Forms the external and internal linings of many organs epithelial tissue. Extracellular material is so thin it is not visible with a light microscope. Epithelial cells rely on nourishment and waste removal via small blood vessels that are found in the adjacent connective tissue. Basement membrane layer between an epithelium and the underlying connective tissue. Basal surface surface of an epithelial cell that faces the basement membrane.
