Cells and Tissues Exam 2 Updated Actual
Questions and CORRECT Answers
Groups of cells with similar structure and function - CORRECT ANSWER Tissues
Name the four primary types of body tissues. - CORRECT ANSWER Epithelium,
Connective tissue, Nervous tissue, Muscle
Where are epithelial tissues found? - CORRECT ANSWER Body coverings, body
linings, glandular tissue
Functions of epithelial tissues. - CORRECT ANSWER Protections, absorption,
filtration, secretion
Cells fit closely together / Tissue layer always has one free surface / Lower surface is bound
by a basement membrane / Avascular (no blood supply) / Regenerate easily - CORRECT
ANSWER Characteristics of Epithelium
What are the classifications of epithelium? - CORRECT ANSWER Simple, one layer.
Stratified, more than one layer.
Shapes of epithelium. - CORRECT ANSWER Squamous, flattened. Cuboidal, cube.
Columnar, column-like.
Single layer of flat cells / Usually forms membranes - Lines body cavities / Lines lungs and
capillaries. - CORRECT ANSWER Simple Squamous
Single layer of cube-like cells / Common in glands and their ducts . Forms walls of kidney
tubules / Covers the ovaries - CORRECT ANSWER Simple Cuboidal
, Single layer of tall cells / Often includes goblet cells, which produce mucus / Lines digestive
tract - CORRECT ANSWER Simple Columnar
Single later, but some cells are shorter than others / Often looks like a double cell layer /
Sometimes ciliated, such as in respiratory tract / May function in absorption or secretion -
CORRECT ANSWER Pseudostratified
Cells at the free edge are flattened / Found as a protective covering where FRICTION is
common / Found in skin, mouth, and esophagus. - CORRECT ANSWER Stratified
Squamous
Surface cells are columnar, cells underneath vary in size and shape. - CORRECT
ANSWER Stratified Columnar
Found everywhere in the body / Includes the most abundant and widely distributed tissues /
Functions: Binds body tissues together, supports the body, provides protection - CORRECT
ANSWER Connective Tissue
Name two dominant characteristics of Connective tissues. - CORRECT
ANSWER Variations in blood supply and extracellular matrix
Non-living material that surrounds living cells - CORRECT ANSWER Extracellular
matrix
What are the two main elements in extracellular matrix? - CORRECT
ANSWER Ground substance and fibers
____ cells in lacunae (cavities) / Composed of: hard matrix of calcium salts, large numbers of
collagen fibers / Used to protect and support the body - CORRECT ANSWER Bone
(Osseous)
Most common cartilage / Composed of: abundant collagen fibers, rubbery matrix / Entire
fetal skeleton is hyaline cartilage - CORRECT ANSWER Hyaline Cartilage
