6.Stratified epithelial tissue may have different cell shapes from the bottom (basal) layer to the top (apical) layer.Which layer determines the shape classification of the tissue? Provide evidence to support your answer. 7.Name the specific type of epithelial being described: a tissue consists of multiple layers of cells, the top layer of which is composed of columnar cells. 8. In your group individually have each person complete this question by themselves on the provided separate sheet of paper . a. Indicate and label the apical surface on each epithelial tissue photomicrograph. b. Indicate and label the basal surface on each epithelial tissue photomicrograph. c. Draw a bracket to indicate the location of the epithelial tissue. d. Name the specific epithelial type. a. b. Tissue = _ simple columnar epithelial _ Tissue = _ stratified squamous epithelial _ APICAL BASAL
9. Within your group, compare your individual answers to the above question. As a group, come to a consensus and label the photomicrographs above. The answer must be agreed on by all group members. MODEL #2: Function of Epithelial Tissue QUESTIONS: 10. Epithelial tissue covers surfaces and provides a barrier between body fluids/air and underlying tissues. Organs need to transport fluids between blood vessels and lumen, which requires the chemicals to pass through the epithelial tissue. a. Label the epithelial tissues drawn above as either simple or stratified. left = simple, right = stratified b. Describe the path that chemicals move for absorption and secretion. Absorption: chemical moves from lumen through tissue into blood vessel; Secretion: chemical moves through tissue into the lumen.
