Human Anatomy and Physiology
Tissues exam questions with
correct solutions.
epithelial tissue - Answer 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 - Answer epithelium: flat
cuboidal - Answer epithelium: cube-shaped
columnar - Answer epithelium: greater in height than width
simple - Answer epithelium: single layer
stratified - Answer epithelium: multiple layers
Simple squamous - Answer 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 - Answer epithelium: single layer of cube-shaped
cells; forms walls of ducts in skin glands and kidney tubules -
secretion, absorption
blood - Answer connective tissue: has living cells; plasma is the
fluid matrix that contains fibers that come into action during
clotting; transports gases, nutrients, wastes, etc.
muscle tissue - Answer tissue: highly specialized to contract in
order to produce movement of some body parts
skeletal muscle - Answer muscle tissue: long, threadlike,
alternating light/dark cross markings called striations, many
nuclei, can stimulate a muscle cell to contract, found in muscles
that attach to bones, controls voluntary movements
cardiac muscle - Answer muscle tissue: alternating light/dark
cross markings called striations, branched, joined end to end,
intricate networks, single nucleus, intercalated disc where cells
touch, cannot stimulate a muscle cell to contract, found in heart,
controls involuntary movements
