Ch. 4 Tissue Flashcards
Simple Squamous Locations
Lining the heart, blood vessels, lymph vessels, and air sacs in the lungs
Simple Squamous Functions
Transfer of gases, fluids by diffusion; secretes lubricating substances
Simple Cuboidal Locations
Kidney tubules, ducts of small glands, surface of ovaries, ducts of pancreas
Simple Cuboidal Functions
Secretion and absorption
Simple Columnar Locations
Bronchioles, fallopian tubes, and spinal cord
Simple Columnar Functions
Ciliary action moves particles
Stratified Squamous Epithelium Locations
(Non-keratinized) linings of the esophagus, mouth, and vagina; (Keratinized) dry epidermis of the skin
Stratified Squamous Epithelium Functions
Provides protection from abrasion, water loss, and foreign invasion
Pseudostratified Ciliated Columnar Epithelium Locations
Upper respiratory tract
Pseudostratified Ciliated Columnar Epithelium Functions

Stratified Cuboidal Epithelium Functions
Secretion and protection
Stratified Columnar Epithelium Locations
Rare; conjunctiva, pharynx, anus, uterus, urethra
Stratified Columnar Epithelium Functions
Protection and secretion

Simple Squamous Epithelium (gas exchange occurs easily)
The proximal tubule of the nephron (kidney tubule) in the kidney is composed of which type of epithelium?
Simple cuboidal epithelium (allows secretion and absorption)
The epithelium of the esophagus is composed of which type of epithelial tissue?
Stratified Squamous Epithelium (to protect against wear and tear)
Which of the three muscle cell types has multiple nuclei?
Skeletal (because they’re larger)
Which types of cell junctions are needed in a mucosal membrane, such as the digestive tract, to keep the digestive enzymes, juices, and bacteria from leaking out?
Tight junctions
