1 layer w/ disc shaped nuclei and sparse cytoplasm

diffusion and filtration

provides a slick friction reducing lining in the lymphatic and cardiovascular system

secretion and absorbtion

kidney tubules, ducts and secretory portions of small glands and ovary surface

goblet cells

absorbtion and secretion

noncilated line digestive tract and gallbladder

ciliated type line small bronchi, uterine tubes, and some regions of the uterus

nuclei are seen @ diff layers

secretion and propulsion of mucus

nonciliated: male sperm carrying ducts

ciliated: trachea

protection of underlying areas subjected to abrasion

external part of skins epidermis

linings of the esophagus, mouth and vagina

streches to permit distension of the urinary bladder

lines the urinary bladder, ureters and part of  the urethra

ductless and produces hormones

secretions include amino acids, proteins, glycoproteins, and steroids

(endocrine system glands)

secrete their products onto body surfaces or into body cavities through a duct

body cavities, oil and salvitory glands

goblet cells

merocrine products are secreted by exocytosis

holocrine- products are secreted by the rupture of gland cells

what is the difference between a mecrine and holocrine gland?

wraps and cusions organs

widely distributed throghout the body

reserves food stores. insulates against heatloss. supports and protects

under skin, around kidneys, w/in abdominin and breast

forms a soft internal skeleton or stroma that supports other cell types

lymph nodes bone marrow spleen

attaches muscles to bones or to other muscles and bone to bone

tendons, ligaments and aponeurosis

w/ stands tension in many directions provides structural strength

 dermis, submucosa of the digestive tract and fibrous organ capsules

supports, reinforces, cushions and resists compression

embryonic skeleton, ends of long bones, nose trachea, and larynx

 more elastic fibers

maintains shape and structure while allowing flexibility

external ear (pinna) and epiglottis

less firm than hyaline w/ thick collagen fibers

provides tensile strength and absorbes compression shock

intervertebral discs, pubic symphysis, and in discs of knee joint

supports, protects, provides levers for muscular actin. store calcium, minerals and fat

bones

transmits eletrical signals from sensory receptos to effectors

brain, spinal cord and peripheral nerves

initiates and controls voluntary movement

skeletal muscles thayt attach to bone or skin

propels blood in circulation

found in walls of heart

have intercalated discs-joints- where cells join together

cadiac has intercalated discs and branches

skeletal muscle doesnt branch or have calated discs

both have striations

white fat stores nutrients

brown fat- consumes nutrients to generate heat

antibodies/ direct attack

two types B and T

 phagocyte

eat different kinds of bad guys

 destroys parasitic worms

(the kind that clog up the lymphatic system)

 histamine production

 (like mast cells)

top layer

forms brain, nerve, and epithelial tissue

stuff in middle

form muscule, connective, and epithelial tissue

underside layer

in certain parts of the body . respond to an injury

release histimines

grow up in bone marrow

Processes___________

support cells__________

 Internal communication

• Brain, spinal cord, and nerves

Muscle tissue:

 Contracts to cause movement

• Muscles attached to bones (skeletal)

• Muscles of heart (cardiac)

• Muscles of walls of hollow organs (smooth)

Epithelial tissue:

 Forms boundaries between different

environments, protects, secretes, absorbs, filters

• Skin surface (epidermis)

• Lining of GI tract organs and other hollow organs

Connective tissue:

 Supports, protects, binds

other tissues together

• Bones

• Tendons

• Fat and other soft padding tissue

fibers

release of inflammatory chemicals

dialation of blood vessels

increase in vessel permeability

clotting occurs

• blood is replaced w/ granulation tissue
• epithelium begins to regenerate
• fibroblasts produce collagen fibers to brige the gap
• debris is phagocytized

• the scab detaches
• fibrous tissue matures; epithelium thickens and begins to resemble adjacent tissue
• results in a fully regenerated epithelium w/ underlying scar tissue
