Last week, students in Mrs. Lawson’s Anatomy and Physiology classes learned more about epithelial tissues through an interactive lab. Students viewed and sketched the six different types of epithelial tissues under the microscope and then compared/contrasted each as far as structure, function, and location in the body.
Epithelial tissues are thin tissues that cover all the exposed surfaces of the body. They form the external skin, the inner lining of the mouth, digestive tract, secretory glands, the lining of hollow parts of every organ such as the heart, lungs, eyes, ears, the urogenital tract, as well as the ventricular system of the brain and central canals of the spinal cord.
Students completed a lab report with all of the information they collected from viewing the tissues. Mrs. Lawson first explained what students should be seeing by using both the book and the microscope, as microscope work can be challenging.
