GH 125 A & P - chapters 4, 5, 6, and 7 Test
With Complete Solution
Histology - ANSWER Study of tissues
Epithelial tissue - ANSWER Covers all body surfaces
Deficient in blood vessels
Rapid reproduction
May contain cilia
Epithelial tissue classification - ANSWER Based on shape and number of
layers:
squamous
cuboidal
columnar
Epithelial functions - ANSWER protection
absorption
filtration
excretion
secretion
sensory reception
Simple squamous epithelium - ANSWER Function: Allows passage of
,materials by diffusion and filtration in sites where protection is not
important; secretes lubricating substances in serosae.
Location: Kidney glomeruli, air sacs of lungs, lining of heart, blood vessels,
and lymphatic vessels; lining of ventral body cavity(serosae)
Stratified squamous epithelium - ANSWER Function:
protects underlying tissues in areas subject to abrasion
Location:
non-keratinized: the moist lining of the esophagus, mouth, and vagina;
keratinized: the epidermis of the skin, a dry membrane.
Simple Squamous epithelium - ANSWER single layer of flattened cells
Function:
transport via absorption
Simple Cuboidal epithelium - ANSWER Function:
secretion and absorption
Location:
Kidney tubules;
ducts and secretory portions of small glands, and
ovary surface
Simple cuboidal epithelium 2 - ANSWER
, Simple Columnar Epithelium - ANSWER Function: Absorption; secretion of
mucus, enzymes, and other substances
Location:
digestive tract (stomach to anal canal), gallbladder and excretory ducts of
some glands; small bronchi, and uterine tubes
Pseudostratified Epithelium - ANSWER Multiple layers due to difference in
cell height, but are really one layer.
Stratified Transitional Epithelium - ANSWER Multiple layers of cells which
appear cuboidal when not stretched, but squamous when stretched; found in
the urinary organs/bladder
Connective tissue - ANSWER A body tissue that provides support for the
body and connects all of its parts
Types of Connective Tissues - ANSWER Blood
Areolar
Adipose
Fibrous
Elastic, Bone, Cartilage
Connective tissue: Blood - ANSWER Function:
transport of respiratory gases, nutrients, wastes, and other substances
Location:
contained within blood vessels
