Exam 2 - Cells and Tissues Questions with
Answers (100% Correct Answers)
Groups of cells with similar structure and function Answer: Tissues
Name the four primary types of body tissues. Answer: Epithelium, Connective
tissue, Nervous tissue, Muscle
Where are epithelial tissues found? Answer: Body coverings, body linings,
glandular tissue
Functions of epithelial tissues. 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 Answer: Characteristics of Epithelium
What are the classifications of epithelium? Answer: Simple, one layer.
Stratified, more than one layer.
Shapes of epithelium. Answer: Squamous, flattened. Cuboidal, cube.
Columnar, column-like.
Single layer of flat cells / Usually forms membranes - Lines body cavities /
Lines lungs and capillaries. Answer: Simple Squamous
Single layer of cube-like cells / Common in glands and their ducts . Forms
walls of kidney tubules / Covers the ovaries Answer: Simple Cuboidal
Single layer of tall cells / Often includes goblet cells, which produce mucus /
Lines digestive tract 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 Answer: Pseudostratified
, 2
Cells at the free edge are flattened / Found as a protective covering where
FRICTION is common / Found in skin, mouth, and esophagus. Answer:
Stratified Squamous
Surface cells are columnar, cells underneath vary in size and shape. 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 Answer: Connective Tissue
Name two dominant characteristics of Connective tissues. Answer: Variations
in blood supply and extracellular matrix
Non-living material that surrounds living cells Answer: Extracellular matrix
What are the two main elements in extracellular matrix? 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
Answer: Bone (Osseous)
Most common cartilage / Composed of: abundant collagen fibers, rubbery
matrix / Entire fetal skeleton is hyaline cartilage Answer: Hyaline Cartilage
Provides elasticity / EX: supports the external ear Answer: Elastic Cartilage
Highly compressible / EX: forms cushion-like discs between vertebrae Answer:
Fibrocartilage
Main matrix element is collagen fibers / Cells are fibroblasts / EX: tengon -
muscle --> bone; ligaments - bone --> bone Answer: Dense Connective Tissue
Most widely distributed connective tissue / Soft, pliable tissue / Contains all
fiber types / Can soak up excess fluid Answer: Areolar Connective Tissue
