Study Notes

Simple Squamous Epithelium

Function: Involved in filtration and diffusion, found in kidneys and lungs; also has a role in secretion within serous membranes.
Location: Lines cardiovascular and lymphatic systems (endothelium), forms serous membranes (mesothelium), and is present in air sacs of lungs and kidney glomeruli.

Simple Cuboidal Epithelium

Function: Primarily serves in secretion and absorption.
Location: Covers ovarian surfaces, lines kidney tubules, and forms parts of glands including thyroid and pancreas.

Nonciliated Simple Columnar Epithelium

Function: Enhances secretion and absorption; secretes mucus to protect digestive and respiratory linings.
Location: Lines the gastrointestinal tract from stomach to anus, as well as ducts of various glands.

Ciliated Simple Columnar Epithelium

Function: Cilia move mucus and particles; aids in moving oocytes through the fallopian tubes.
Location: Lines bronchioles, fallopian tubes, uterus, and parts of the central nervous system.

Pseudostratified Columnar Epithelium

Function: Ciliated type traps and eliminates foreign particles; nonciliated type offers absorption and protection.
Location: Ciliated lines upper respiratory airways; nonciliated lines ducts of glands and male reproductive structures.

Stratified Squamous Epithelium

Function: Provides protection against physical abrasion, water loss, UV radiation, and pathogen invasion.
Location: Keratinized type forms skin’s outer layer; non-keratinized type lines moist surfaces (mouth, esophagus, vagina).

Stratified Cuboidal Epithelium

Function: Primarily offers protection with limited secretion and absorption.
Location: Found in ducts of sweat glands, esophageal glands, and parts of male urethra.

Stratified Columnar Epithelium

Function: Provides protection and facilitates secretion.
Location: Lines part of the urethra, large gland ducts, and certain mucous membranes.

Transitional Epithelium

Function: Enables stretching of urinary organs while maintaining a protective lining.
Location: Lines the urinary bladder, ureters, and urethra.

Endocrine Glands

Function: Secrete hormones to regulate metabolism and physiological activities for homeostasis.
Location: Varies widely across the body, dependent on the specific glands involved, such as thyroid and adrenal glands.
