Document Summary

Tissue: groups of cells that are similar in structure and function. Stratified epithelia: 2 or more layer of cells: list the four basic tissue types in the human body. Epithelial tissue: tissue that lines body cavities and covers surface. sheet of cells that covers the body surface or lines a body cavity. matrix; important in protection and support and to react to it cavity. skin. State the functions and some of the characteristics of epithelial tissues. Epithelial tissue: sheet of cells that covers the body surface or lines a body. Connective tissue: tissue type composed largely of nonliving extracellular. Nervous tissue: tissue that enables us to be aware of the external environment. Functions: protection: epithelium covering the body protects from bacterial invasion and chemical damage, absorption: lines the stomach and small intestines, ex: kidneys, filtration: ex: kidneys, excretion, secretion: ex: kidneys, sensory reception: gland ii. Epithelial cell shapes: simple squamous: epithelium that has one layer]
