Simple squamous epithelium
-found in the lungs, lining of heart and blood vessels, kidney, and external covering
around the organs such as the esophagus;
-function:it's thin so it allows for easy diffusion and filtration. Also reduces friction.
Simple cuboidal epithelium
-found in the ducts, kidney tubules, glands;
-function: secretion and absorption
Simple columnar epithelium
-found in the digestive system and larger ducts;
-function: secretion and absorption
Pseudostratified columnar epithelium
-found in the nasal cavity, trachea, bronchi, and portions of the male reproductive tract;
-function: protection and secretion
Stratified squamous epithelium
-surface of skin; found in the lining of mouth, throat, esophagus, rectum, anus and
vagina;
-function: provides physical protection against abrasion, pathogens, and chemical
attack.
Stratified cuboidal epithelium
-found in the lining of some ducts (rare); -function: protection, secretion and absorption
Stratified columnar epithelium
-found in small areas of the pharynx, epiglottis, anus, mammary gland, salivary ducts
and urethra;
-function: protection
Transitional epithelium
-found in the urinary bladder, renal pelvis and ureters;
-function: permits expansion and recoil after stretching.
(the picture is of the tissue at the relax stage.)
Areolar connective tissue
-Function: wraps and cushions organs; protects against bacteria; reservoir of water
-Location: widely distributed under epithelia of body
Adipose connective tissue
-Function: wraps and cushions organs; protects against bacteria; reservoir of water
-Location: under skin, around eyes, around kidneys, in bones and abdomen
Reticular connective tissue
-Function: fibers form a soft internal skeleton that supports other tissues
-Location: lymph organs, spleen, and bone marrow
Dense regular connective tissue
-Function: attaches muscles to bone/ muscles to muscles; withstands great tensile
stress in one direction
-Location: tendons and ligaments
