A&P 2113L- Tissue

simple squamous epithelium

fxn: allows materials to pass by diffusion and filtration, found in kidney glomeruli, air sacs of lungs; lining of heart, blood vessels (capillaries), and lymphatic vessels

simple cuboidal epithelium

fxn: secretion and absorption, found in kidney tubules, ducts of small glands; ovary surface

simple columnar epithelium

fxn: absorption and secretion of mucus and enzymes, lines digestive tract (excluding pharynx, esophagus, and anus)

pseudostratified columnar epithelium

fxn: secretion and movement of mucus, ciliated: lines trachea (bronchioles) and upper respiratory tract, nonciliated in males’: sperm-carrying ducts and ducts of large glands

stratified squamous epithelium

fxn: protection, nonkeratinized: pharynx, tongue, vagina, and anus, keratinized: epidermis of the skin

(stratified) transitional epithelium

fxn: stretching and distension, found in ureters, bladder, and part of the urethra

loose areolar connective tissue

fxn: wraps and cushions organs, found under epithelia

loose adipose connective tisue

fxn: provides reserve food fuel, insulates against heat loss; supports and protects organs, found under skin, around kidneys and eyeballs; within abdomen and in breasts

loose reticular connective tissue

fxn: fibers form soft internal skeleton that supports leukocytes, mast cells, and macrophages, found in lymphoid organs

dense regular connective tissue

fxn: attaches muscles to bone or to muscle, found in tendons, most ligaments, aponeuroses

dense irregular connective tissue

fxn: provides structural strength, withstands tension, found in fibrous capsules of organs joints, dermis of the skin, digestive tract, pericardium, meninges, 4 heart valves

dense elastic connective tissue

fxn: allows tissue to recoil after stretching, found in large arteries

hyaline cartilage

fxn: supports and reinforces, serves as a cushion, found in skeleton- covers the ends of long bones in joints, cartilage in ribs, nose, trachea, larynx

elastic cartilage

fxn: maintains shape of a structure while allowing flexibility, found external ear (pinna); epiglottis

fibrocartilage

fxn: absorbs compressive shock, found in intervertebral discs, pubic symphysis, knee joint discs, and meniscus

compact bone

fxn: supports and protects by enclosing body structures

blood

fxn: transports respiratory gases, nutrients, wastes, etc., found in blood vessels

skeletal muscle

fxn: voluntary movement, found attached to bone and sometimes skin

cardiac muscle

fxn: involuntarily propels blood into circulation, found in the walls of the heart

smooth muscle

fxn: involuntarily propels substances or objects along passageways, found in the walls of hollow organs

nervous tissue

fxn: transmit electrical signals from sensory receptors and to effectors, found in brain, spinal cord, and nerves
