Location and function of tissue types
Terms in this set (16)
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.
Psuedostratified ciliated columnar epithelium
Function: Secretion, particularly of mucus; propulsion of mucus bu ciliary action.
Location: nonciliated type in male's sperm-carrying ducts and ducts of large glands; ciliated variety lines the trachea, most of 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
Function: gives rise to all other connective tissue types
Location: primarily in embryo
Areolar connective tissue
Function: wraps and cushions organs
Location: widely distributed under epithelia of body
Function: provides reserve fuel; insulates against heat loss; supports and protects organs
Location: under skin, around kidneys and eyeballs, within abdomen, in breasts.
Reticular connective fibers
Function: fibers form a soft internal skeloteton that supports other cell types, including white blood cells, mast cells, and macrophages
Location: lymphoid organs (lymph nodes, bone marrow, spleen)
Dense regular connective tissue
Function: attaches muscles to bones or to muscles; attaches bones to bones; withstands great tensile stress when pulling force is applied in one direction
Location: tendons, most ligaments, aponeuroses
Elastic Connective tissue
Function: allows recoil of tissue following stretching; maintains pulsatile flow of blood through arteries; aids passive recoil of lungs following inspiration
Location: walls of large arteries; within certain ligaments associated with vertebral column, within the walls of the bronchial tubes
Dense irregular connective tissue
Function: able to withstand tension exerted in many directions; provides structural strength
Location: fibrous capsules of organs and joints; dermis of the skin; submucosa of digestive tract
Function: supports and reinforces; has resilient cushioning properties; resists compressive stress
Location: forms most of the embryonic skeleton; covers the ends of long bones in joint cavities; forms the costal cartilages of the ribs, cartilages of the nose, trachea, and larynx.
