Keep on beginning and failing. Each time you fail, start all over again, and you will grow stronger until you have accomplished a purpose - not the one you began with perhaps, but one you’ll be glad to remember

Simple Squamous
Flattened cells
all cells have a free surfaces and are attached to basement membrane
Usually lining blood vessels, air sacs of lungs

Glandular Epithelium
Secretion of a product
goblet cells
found in PSCC and columnar epithelium
