Terms in this set (20)
group of similar cells that perform a particular function
epithelial, connective, muscle, nervous
Tissue that covers outside of the body and lines organs and cavities.
squamous epithelial cells
Flat irregularly shaped cells
Found on skin, heart vessels
cuboidal epithelial cells
are box-shaped, and the nuclei are near the center of each cell
Cells shaped like bricks standing on end.
arranged in layers
the study of the microscopic structure of tissues
simple squamous epithelium
Function: Allows passage of materials by diffusion and filtration in sites where protection is not important; secretes lubricating substances in serosae.
Location: Kidney glomeruli, air sacs of lungs, lining of heart, blood vessels, and lymphatic vessels; lining of ventral body cavity(serosae)
simple cuboidal epithelium
Function: secretion and absorption
Location: Kidney tubules; ducts and secretory portions of small glands, ovary surface.
simple columnar epithelium
Function: Absorption; secretion of mucus, enzymes, and other substances; ciliated type propels mucus (or reproductive cells) by ciliated action.
Location: nonciliated type lines most of the digestive tract (stomach to anal canal), gallbladder and excretory ducts of some glands; ciliated variety lines small bronchi, uterine tubes, and some regions of the uterus.
pseudostratified columnar epithelium
tissue that consists of a single layer of irregularly shaped and sized cells that give the appearance of multiple layers; found in ducts of certain glands and the upper respiratory tract
stratified squamous epithelium
Function: protects underlying tissues in areas subject to abrasion
Location: nonkeratinized type forms the moist lining of the esophagus, mouth, and vagina; keratinized type forms the epidermis of the skin, a dry membrane.
stratified cuboidal epithelium
Location: Largest ducts of sweat glands, mammary glands, and salivary glands.
stratified columnar epithelium
Function: protection and secretion
Location: rare in the body; small amounts in male urethra and in large ducts of some glands
function: stretches readily and permits distension of urinary organ by contained urine
Location: lines the ureters, urinary bladder, and part of the urethra
Composed of cells that are specialized to produce and secrete substances.
secrete chemical substances into ducts that lead either to other organs or out of the body
a ductless gland that secretes hormones directly into the bloodstream
