simple squamous epithelium

~one layer of flat cells

~forms capillaries to permit exchanges of materials

~lines arteries and veins and is smoothe to prevent abnormal blood clotting

Term

Definition

stratified squamous epithelium

~many layers of cells; surface cells are flat

~forms the epidermis of the skin

~forms the lining of the mouth and esophagus

Definition

cuboidal epithelium

~one layer of cube shaped cells

~secretes the hormone of the thyroid gland

~secretes saliva of salivary gland

Term
unicellular glands
Definition
consist of only one cell;
goblet cells that secrete mucus
Term
exocrine glands
Definition
have ducts to take their secretions to their site of action; salivary glands and sweat glands,
Term

blood

~made of cells in the liquid matrix called plasma

~transports oxygen and nutrients and contains cells to destroy pathogens

~ the cells are produced in red bone marrow

Term

Definition

areolar connective tissue

~made of fibroblasts in a matrix of tissue fluid, collagen and elastin fibers

~beneathe the skin and the epithelium of muucous membranes; has white blood cells to destroy pathogens

Definition

elastic connective tissue

~made primarily of elastin fibers

~surrounds the alveoli of the lungs and contributes to normal exhalation

bone

~made of osteocytes in a matrix of calcium salts and collagen

Definition

cartilage

~made of chondrocytes in a matrix that is smooth and flexible

~provides a smooth surface to prevent friction on joint surfaces

~forms rings to keep trachea open

Term

Definition

transitional epithelium

~many of laters of cells; surface cells are alternately rounded or flat

~permits stretching of the urinary bladder as it fills

Term

Definition

columnar epithelium

~one layer of cells that are taller than they are wide

~forms the stomach lining and secretes gastric juices

~forms the lining of the small intestine and absorbs nutrients

~may have microvilli to increase the surface area for absorbtion

Term

Definition

ciliated epithelium

~columnar cells with cilia on their free surfaces

~lines the trachea, and sweeps mucus and bacteria toward the pharynx

~ lines the fallopian tubes to sweep an ovum toward the uterus
