Study Notes
Types of Epithelial Cells
-
Simple Squamous Epithelium
- Located in air sacs of lungs, lining of the heart, and blood/lymphatic vessels.
- Facilitates the passage of materials through diffusion and filtration.
- Secretes lubricating substances to reduce friction.
-
Simple Cuboidal Epithelium
- Found in ducts and secretory portions of small glands as well as kidney tubules.
- Primarily involved in secretion and absorption activities.
-
Simple Columnar Epithelium
- Ciliated version present in bronchi, uterine tubes, and uterus.
- Functions in absorption and secretion of mucus and enzymes.
- Non-ciliated variety located in the digestive tract and bladder.
-
Pseudostratified Columnar Epithelium
- Lines the trachea and much of the upper respiratory tract.
- Secretes mucus, which is then moved by cilia to trap and expel debris.
-
Stratified Squamous Epithelium
- Lines the esophagus, mouth, and vagina.
- Provides protection against abrasion and friction.
-
Stratified Cuboidal Epithelium
- Located in sweat glands, salivary glands, and mammary glands.
- Serves as protective tissue.
-
Stratified Columnar Epithelium
- Found in the male urethra and ducts of some glands.
- Functions in secretion and protection.
-
Transitional Epithelium
- Lines the bladder, urethra, and ureters.
- Allows urinary organs to expand and stretch as they fill.
