Superficial epidermis
Mostly dense connective tissue
Underlying dermis
Surface epithelium -Type depends on site
Underlying loose connective
tissue (lamina propria)
Lines all body cavities that open to the exterior body surface
Often adapted for absorption or secretion

Surface simple squamous epithelium
Underlying areolar connective tissue
Lines open body cavities that are closed to the exterior of the body
