Ex 6

simple squamous

mesothelium, alveoli, glomerular capsule, endothelium of capillaries

mesothelium

secretion of serous fluid into serous cavity

alveoli

single layer of squamous cells creates a short distance for diffusion of oxygen and CO2

glomerular capsule

filtration of blood to form urine filtrate

endothelium of capillaries

single layer of squamous cells creates a short distance for diffusion of substances between blood and interstitial fluid

simple cuboidal

walls of kidney tubules, glands

walls of kidney tubules

modify urine filtrate by absorption of substances from the filtrate and secretion of other substances into the filtrate

glands

secretion of products made by the simple cuboidal epithelial cells

simple columnar

lining of stomach and intestines, lining of uterine tubes, central canal of spinal cord

lining of stomach and intestines(non ciliated)

secretion of digestive juices by epithelial cells and secretion of mucus by goblet cells; small intestine has microvilli to increase surface area for absorption of nutrients

lining of uterine tubes(ciliated)

epithelial cells have cilia that help move the egg to the uterus

central canal of spinal cord(ciliated)

ciliated epithelial cells move cerebrospinal fluid

stratified squamous

surface of skin, lining of mouth, esophagus, anus, vagina

surface of skin(keratinized)

epithelial layer of skin is a tough, dry, waterproof outer surface that forms a protective barrier

lining of mouth, esophagus, anus, vagina(non keratinized)

moist epithelial layer that forms a protective barrier in areas subject to abrasion and friction

urothelium(transitional)

lining of bladder, ureters, and parts of urethra

lining of bladder, ureters, and parts of urethra

provides a protective barrier that permits distension

pseudostratified columnar

lining of nasal cavity, trachea, and bronchi, lines larger ducts of ,any glands, epididymis, part of male urethra

lining of nasal cavity, trachea, bronchi(ciliated)

secretion of mucus by goblet cells; cells have cilia, which move mucus toward the pharynx

lining of larger ducts of glands, epididymis, part of male urethra(non ciliated)

epithelial cells are involved in absorption, secretion, and protection

loose connective tissue

areolar, adipose, reticualr

areolar- beneath all epithelial tissues

binds epithelium to underlying tissues and allows nutrients to diffuse to epithelial cells

adipose- under skin and surrounding organs

stores lipids for fuel and thermal insulation; cushioning organs

reticular- liver, spleen, lymph nodes

forms support of these soft organs

dense connective tissue

regular, irregular, elastic

dense regular- forms ligaments, tendons, aponeuroses

resists pulling force at attachment points

dense irregular- skin

resists pulling forces from many different directions that would tear skin when skin is stretched

elastic- lungs, trachea, bronchi, aorta

allows respiratory organs to recoil after inhalation; recoil of elastic tissue helps push blood through cardiovascular system

cartilage

hyaline, fibrous, elastic

hyaline- ends of long bones; trachea and bronchi; anterior ends of ribs; embryonic skeleton

smooth surface that is resilient and reduces friction at joint; provide support and flexibility to ensure an open airway; connects to ribs to sternum with breastplate; provides template for bone formation

fibrous- intervertebral discs; cartilage pads in knee; pubic symphysis

provide strength to discs that form joints between vertebrae and act as shock absorbers; provide cushioning for bones forming knee joints; forms strong, flexible joint between hip bones

elastic- external ear; auditory tube; epiglottis of larynx

provide support and maintains shape of external ear; provides support and elasticity to auditory tube as it changes diameter to equalize pressure in middle ear; provides support and elasticity to epiglottis as it folds to block entrance to trachea while swallowing food and liquid

bone

compact, spongy

compact bone- exterior of bones

support, protection, storage of minerals

spongy bone- interior of bones

support, protection, storage of minerals

blood components

plasma, RBC, WBC, platelets

plasma- liquid part of blood in arteries, capillaries, veins

transport of nutrients, blood gases, wastes, chemicals, messenegers, blood cells and platelets

RBC- formed element of blood in arteries, capillaries, veins

transport of blood gases

WBC- formed element of blood, can leave blood vessels and enter infected tissues

attack pathogens and other substances that invade the body

platelets- formed element of blood

participate in blood clotting

muscle tissues

skeletal, cardiac, smooth

skeletal muscle tissue- attached to bone and skin

movement of bones and skin; contraction generates heat

cardiac muscle tissue- wall of heart

movement of blood through cardiovascular system

smooth muscle tissue- walls of digestive tract organs; arteries and veins; ureters, bladder, urethra; intrinsic muscle of eye

movement of food through digestive tract; contraction and relaxation controls blood flow and blood pressure; movement of urine through urinary tract; contraction and relaxation controls pupil size
