  2. Histology Slides for the Epithelial, Connective and Integumentary Tissues • Slides are presented in order of magnification • As you view the following slides, make sure you can accomplish these goals: • Can you identify the tissue observable on the slides? • Can you identify the specific structures or layers indicated by the numbered arrows or brackets? • At the end of a sequence you will find the answers to the above for each vessel and layer.
