Epithelial Tissue Locations/Functions

Allows rapid movement of molecules across surface; Lines alveoli, endothelium, mesothelium

Designed for absorption and secretion; Structural components of glands.

Move extracellular objects along; Lines the bronchioles and uterine tubes

Secrete Mucin; Lines digestive tract from stomach to anal canal

Protection and Mucin Secretion; Large passageways of respiratory system

Protection; Male urethra and epididymis

Protection against abrasion and friction; Epidermis

Protection; Lines oral cavity, pharynx, esophagus, vagina, anus

Protection and Secretion; Walls of ducts in most exocrine glands

Protection and Secretion; Large ducts of salivary glands, parts of male urethra

Allows for stretching; Urinary tract

Protection, binds skin and some epithelial tissue to deeper tissue; Papillary layer of dermis, subq layer, surrounding organs, nerve and muscle cells, blood vessels

Stores energy, generates heat in newborns; Subcutaneous layer, surrounds and covers some organs

Provides stroma to lymphatic organs; lymph nodes, red bone marrow, spleen

Attaches bone to bone and muscle to bone; ligaments and tendons

Withstands stresses applied in all directions, durable; Most of dermis, periosteum, perichrondium, epineurium, epimysium

Allows fro stretching and recoil; Walls of elastic arteries, trachea, vocal chords

Profvides support, fetal skeleton; Tip of nose, trachea, larynx costal cartilage, etc.

Resists compression, shock absorber; Intervertebral discs, pubic symphysis, menisci of knee joints

Maintains shape while permitting extensive flexibility; external ear, epiglottis
