Human Anatomy and
Physiology Tissues

, epithelial tissue - CORRECT ANSWERS-tissue: cells are avascular (closely packed
together, little or no intercellular material between adjacent cells); major roles include
secretion, absorption, protection, and synthesizing hormones; covers external body
surfaces and lines inner walls of cavities and organs; has basement membrane
(attachment) and free surface (exposed side); classified by shape and layer

squamous - CORRECT ANSWERS-epithelium: flat

cuboidal - CORRECT ANSWERS-epithelium: cube-shaped

columnar - CORRECT ANSWERS-epithelium: greater in height than width

simple - CORRECT ANSWERS-epithelium: single layer

stratified - CORRECT ANSWERS-epithelium: multiple layers

simple squamous - CORRECT ANSWERS-epithelium: singer layer of flat cells; lines
inside wall of blood vessels, forms walls of capillaries and lung air sacs - absorption by
diffusion, filtration, osmosis; secretion

simple cuboidal - CORRECT ANSWERS-epithelium: single layer of cube-shaped cells;
forms walls of ducts in skin glands and kidney tubules - secretion, absorption

simple columnar - CORRECT ANSWERS-epithelium: single layer of column-shaped
cells; lines inside walls of stomach and intestines - protection, secretion, absorption,
moving of mucus w/ cilia

stratified squamous - CORRECT ANSWERS-epithelium: multiple layers of cells, with
cells along free edge flattened in shape; superficial layer of the skin, mouth, and throat
(friction) - protection

pseudostratified columnar - CORRECT ANSWERS-epithelium: single layer of irregularly
shaped cells that appear multi-layered, often with cilia; lines inside walls of larynx,
trachea, and bronchi - protection

transitional - CORRECT ANSWERS-epithelium: multiple layers of spherical or
irregularly shaped cells; lines inside walls of urinary bladder and ureter - permits
stretching

glandular - CORRECT ANSWERS-epithelium: specialized epithelium that manufacture
and secrete products

exocrine glands - CORRECT ANSWERS-glands that empty products into ducts. the
ducts transport products to the body surface or into a cavity. (salivary glands, oil glands
in skin, sweat glands)
