Tissue Types Flashcards
Simple Squamous Epithelium
LOCATIONS: Mesothelia lining pleural, pericardial, and peritoneal cavities; endothelia lining heart and blood vessels; portions of kidney tubules (thin sections of nephron loops); inner lining of cornea; alveoli of lungs
FUNCTIONS: Reduces friction; controls vessel permeability; performsabsorption and secretion
Stratified Squamous Epithelium
LOCATIONS: Surface of skin; lining of mouth, throat, esophagus, rectum, anus, and vagina FUNCTIONS: Provides physical protection against abrasion, pathogens, and chemical attack
Simple Cuboidal Epithelium
LOCATIONS: Glands; ducts;portions of kidney tubules; thyroid gland FUNCTIONS: Limited protection, secretion, absorption
Stratified Cuboidal Epithelium
LOCATIONS: Lining of some ducts(rare) FUNCTIONS: Protection, secretion, absorption
Transitional Epithelium
LOCATIONS: Urinarybladder; renal pelvis;ureters FUNCTIONS: Permits expansion and recoil after stretching
Simple Columnar Epithelium
LOCATIONS: Lining ofstomach, intestine, gallbladder,uterine tubes, and collectingducts of kidneys FUNCTIONS: Protection, secretion, absorption
Pseudostratified Ciliated Columnar Epithelium
LOCATIONS: Lining ofnasal cavity, trachea, andbronchi; portions of malereproductive tract FUNCTIONS: Protection, secretion, move mucus with cilia
Areolar Tissue
LOCATIONS: Within and deep to thedermis of skin, and covered by the epithelial lining of the digestive, respiratory, and urinary tracts; between muscles; around joints, blood vessels, and nerves FUNCTIONS: Cushions organs; provides support but permits independent movement; phagocytic cells provide defense against pathogens
Adipose Tissue
LOCATIONS: Deep to the skin, especially at sides, buttocks, and breasts; padding around eyes and kidneys FUNCTIONS: Provides padding and cushions shocks; insulates (reduces heat loss); stores energy
Reticular Tissue
LOCATIONS: Liver, kidney, spleen, lymph nodes, and bone marrow FUNCTIONS: Provides supporting framework
Dense Regular Connective Tissue
LOCATIONS: Between skeletal muscles and skeleton (tendons and aponeuroses); between bones or stabilizing positions of internal organs (ligaments); covering skeletal muscles; deep fasciae FUNCTIONS: Provides firm attachment; conducts pull of muscles; reduces friction between muscles; stabilizes positions of bones
Dense Irregular Connective Tissue
LOCATIONS: Capsules ofvisceral organs; periostea and perichondria; nerve and muscle sheaths; dermis FUNCTIONS: Provides strength to resist forces from many directions; helps prevent over expansion oforgans, such as the urinary bladder
