Epithelial and Connective Tissue

simple squamous

Location: lining of blood vessels, kidney, the heart, alveoli of lungs, and lining of ventral body cavity

Function: filtration, diffusion, osmosis, and secretion of lubricating substances

simple cuboidal

Location: lining of blood vessels, kidney, the heart, alveoli of lungs, and lining of ventral body cavity

Function: filtration, diffusion, osmosis, and secretion of lubricating substances

simple columnar

Location: non-ciliated lines the stomach and intestinal tract. ciliated are in uterine tube, parts of the uterus, and small bronchi

Function: absorption, secretion of mucous through goblet cells in GI tract, and propels mucous (cilia)

pseudostratified columnar

Location: ciliated lines the trachea and upper respiratory tract. nonciliated in sperm ducts and ducts of large glands

Function: secretion of mucus and propulsion of mucus by ciliary action.

stratified squamous

Location: nonkeratinized in lining of the mouth, esophagus, and vagina. keratinized forms epidermis

Function: protection against abrasion, pathogens, and chemical exposure.

transitional epithelium

Location: lines the urinary bladder, ureters, and part of the urethra.

Function: allows for stretching and distension of the urinary organs.

hyaline cartilige

Location: forms most of the embryonic skeleton, covers the ends of long bones, and supports the nose, ribs, trachea, and larynx.

Function: provides flexibility, support, and reduces friction between bony surfaces.

elastic cartilage

Location: found in the external ear, epiglottis.

Function: supports and maintains the shape of the epiglottis and outer ear

fibrocartilage

Location: found in intervertebral discs, pubic symphysis, and menisci of the knee. Function: able to withstand compression and is weight-bearing

loose areolar

Location: commonly found epithelia of tissue of skin, surrounding capilaries, and packages internal organs

Function: cushioning and packaging

loose adipose

Location: under the skin, in long bones, breast, abdominal area, around kidneys, and eyeballs

Function: store fat for energy, insulation, protection, and support of other tissues/organs

loose reticular

Location: lymph nodes, spleen, bone marrow

Function: supports other cells

dense regular

Location: tendons, ligaments

Function: strong attachment between muscle and bone

dense irregular

Location: fibrous capsule of joint, dermis, submucosa of GI tract

Function: to provide strength and withstand tension in many different directions
