SIMPLE SQUAMOUS EPITHELIUM - Answer location: air sacs of lungs, lining of heart, blood
vessels and lymphatic vessels
function: allows material to pass by diffusion; secretion
SIMPLE CUBOIDAL EPITHELIUM - Answer location: kidney tubules, ovary surface
function: secretion and absorption
SIMPLE CILIATED COLUMNAR EPITHELIUM - Answer location: bronchi tubes, digestive tract,
uterine tubes
function: absorption; secretion of mucus and other substances
STRATIFIED SQUAMOUS KERATINIZED EPITHELIUM - Answer location: epidermis of skin
function: protects underlying tissue from abrasion
STRATIFIED SQUAMOUS NONKERATINIZED EPITHELIUM - Answer location: oral cavity,
pharynx, anus, and vagina
function: protects underlying tissue from abrasion
STRATIFIED CUBOIDAL EPITHELIUM - Answer location: kidney tubules and small ducts of
glands
function: protection of the ducts of sweat, mammary, and salivary glands
TRANSITIONAL EPITHELIUM - Answer location: lining of urinary bladder and ureters
function: stretches readily, permits storage of urine
, PSEUDOSTRATIFIED CILIATED COLUMNAR EPITHELIUM - Answer location: in males' sperm
ducts, trachea, upper respiratory tract
function: secretion of substances, propulsion of mucus
LOOSE AREOLAR CONNECTIVE TISSUE - Answer location: widely distributed under epithelia of
body (lamina propria, packages organs, surrounds capillaries)
function: wraps and cushions organs, macrophages eat bacteria
LOOSE RETICULAR CONNECTIVE TISSUE - Answer location: lymphoid organs (lymph nodes,
bone marrow, spleen)
function: soft internal skeleton that supports other cells (WBC, mast cells, macrophages)
ADIPOSE TISSUE - Answer location: under skin sub-Q, around kidneys and eyeballs, breasts
function: fuel reserve, insulation, support
DENSE REGULAR COLLAGENOUS CONNECTIVE TISSUE - Answer location: tendons, ligaments
function: attaches muscles to bones or to other muscles
DENSE IRREGULAR COLLAGENOUS CONNECTIVE TISSUE - Answer location: fibrous capsules of
organs and joints, dermis of skin
function: withstand tension exerted in many directions
DENSE ELASTIC CONNECTIVE TISSUE - Answer location: walls of large arteries and bronchial
tubes
function: allows tissue to recoil after stretching, maintain flow of blood
HYALINE CARTILAGE - Answer location: embryonic skeleton, covers ends of long bones in
joint cavities; cartilages of nose, trachea, ribs to sternum, and larynx
function: support and reinforcement; resilient cushion and stress resistor
