Function: Allows passages of materials by diffusion and filtration in sites where protection is not important; secretes lubricating sustances in serosae

Location: Kidney glomerull; air sacs of lungs; lining of hearts, blood vessels, and lymphatic vessels; lining of ventral body cavity (serosae)

Function: Secretion and absorption

Location: Kidney tubules; ducts and secretory portions of small glands; ovary surface

Function: Absorption; secretion of mucus, enzymes, and other substances; ciliated type propers mucus (or reprodcutive cells) by ciliary 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

Function: Secretion, particularly of mucus; propulsion of mucus by 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.

Function: Protects underlying tissues in areas subjected to abrasion

Location: Nonkerantinized type fors the most linings of the esophagus, mouth, and vagina; keratinized variety forms the epidermis of the skin, a dry membrane

Function: Protection

Location: Largest ducts of sweat glands, mammary glands, and salviary glands

Function: Stretches readily and permits distension of urinary organ by contained urine.

Location: Lines the ureters, urinary bladder, and parts of the urethra

Function: Wraps and cushions organs; its macrophages phagocytize bacteria; plays important role in inflammation; holds and conveys tissue fluids

Location: Widely distributed under epithelia of body, e.g. forms lamina propria of mucous membranes; packages organs; surround capilaries

Function: Provides reserve fuel; insulates against heat loss; supports and protects organs

Location: Under skin; around kidneys and eyeballs; within abdomen; in breasts.

Function: Attaches muscles to bones or to mucles; attaches bone to bones; withstands great tensile stress when pulling force is applied in one direction

Location: Tendons, most ligament, apneuroses.

Function: Supports and reinforces; has resilent cushioning properties; resists compressive stress.

Locaiton: Forms most of the embryonic skeleton; covers the end of long bones in joint cavaties; forms costal cartilage of the ribs; cartilage of the nose, trachea, and larynx

Function: Transport of respiratory gasses, nutrients, wastes, and other substances

Location: Contained within blood vessels

Function: Transmit electircal signals from sensory receptors and to effectors (muscles&glands) which control their activity.

Location: Brain, spinal cord, and nerves

Function: Voluntary movement; locomotion; manipulation of the enviornment; facial expression; voluntary control

Location: In skeletal muscles attached to bones or occasionally to skin

Function: Propels substances or onjects (foodstuffs, urine, a baby) along internal passageways; involuntary control

Location: Mostly in the walls of hollow organs
