Types Of Tissues Flashcards
Simple epithelium
Contains one layer of cells
Stratified epithelium
Contains two or more layers of cells
Squamous
Thin, flattened cells; the width of each cell is greater than its height
Cuboidal
“Cubes” of cells; the width, depth, and height of each cell are approximately equal
Columnar
Taller, cylindrical cells; the height of each cell is greater than its width
Simple squamous
Lines body cavities and the vasculature, offering a barrier to transport or functioning as an exchange system, often by simple diffusion
Simple cuboidal
Lines ducts of glands and kidney tubules, offering a passageway with or without the ability to absorb and secrete
Simple columnar
Lines much of the gastrointestinal system, offering a surface for absorption and secretion
Pseudostratified
Lines the trachea, bronchi of the lungs, and ductus deferens, offering a passageway with or without barrier or secretory functions
Stratified squamous
Forms the skin and lines the oral cavity, esophagus, and vagina, offering a protective surface; the skin may have a protective layer of keratin overlying the epithelium
Stratified cuboidal
Lines the ducts of sweat glands and other large exocrine glands, offering a conduit and/or serving as a barrier to transport
Stratified columnar
Lines the large ducts of exocrine glands, offering a conduit and serving as a barrier
Transitional
Lines the urinary system, offering a conduit; has the ability to distend
