TITTLE Animal Tissues : Epithelial Tissues OBJECTIVES 1. To recognize the four basic tissues and their common mammalian subtypes. 2. To list the functions of the four basic tissues and their common mammalian subtypes 3. To explain how the four basic tissues combine to make organs MATERIALS 1. Compound microscope 2. Prepared slides of : 2.1. Whole mount of mesentery (simple squamous epithelium) 2.2. Section of trachea 2.3. Small intestine (preferably of the ileum) 2.4. Section of esophagus 2.5. Section of mammalian skin PROCEDURE 1. The prepared slides was observed starting from the simple squamous epithelium slide, then the section of trachea, small intestine, section of esophagus and lastly, the section of mammalian skin. 2. While observing all of the tissues’ slides, these things have been identified so that the most subtypes of epithelial tissue could be recognized. a. The shape of the outermost cells, whether they are squamous (scalelike or flat), cuboidal, or columnar. b. The number of layers of cells. They are simple if there was only one layer of cells. They are stratified if there was two or more layer of cells. 3. The results has drawn. RESULTS
