Histology

Function: Simple squamous epithelium

Function: Simple squamous epithelium

allows materials to pass by diffusion and filtration in sites where protection is not important; secretes lubricating substances in serosae

Location: Simple squamous epithelium

Air sacs of lungs; lining of heart, blood vessels, and lymphatic vessels

Function: Simple cuboidal epithelium

secretion and absorption

Location: Simple cuboidal epithelium

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

Function: simple columnar epithelium

absorption; secretion of mucus, enzymes, and other substances; ciliated type propels mucus (or reproductive cells) by ciliary action

Location: Simple columnar epithelium

Nonciliated type lines most of the digestive tract (stomach to rectum), gallbladder, and excretory ducts of some glands; ciliated variety lines small bronchi, uterine tubes, and some regions of the uterus.

Function: Pseudostratified columnar epithelium

secrete substances, particularly mucus; propulsion of mucus by ciliary action

Location: Pseudostratified columnar epithelium

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: Stratified squamous epithelium

protects underlying tissues in areas subjected to abrasion

Location: Stratified squamous epithelium

esophagus, mouth, and vagina

Function: Transitional epithelium

stretches readily and permits distension of urinary organ by contained urine

Location: Transitional epithelium

lines the ureters, bladder, and part of the urethra

Function: Loose connective tissue areolar

wraps and cushions organs, its macrophages and phagocytes bacteria plays an important role in inflammation, holds and conveys tissue fluid

location: Areolar loose connective tissue

widely distributed under epithelia of body; forms lamina propria of mucous membranes; packages organs; surrounds capillaries

Function: Adipose loose connective tissue proper

Provides reserve fuel, insulates against heat loss, supports and protects organs

location of adipose loose connective tissue

under skin; around kidneys and eyeballs; within abdomen; in breasts

Location: dense regular connective tissue

tendons, most ligaments

Function: Dense regular connective tissue

attaches muscles to bones or to muscles; attaches bones to bones;

Function: Hyaline cartilage tissue

Supports and reinforces; serves as resilient cushion; resists compressive stress.

Location: Hyaline cartilage tissue

Forms most of the embryonic skeleton; covers the ends of long bones in join cavities; forms costal cartilages of the ribs; cartilages of the nose, trachea, and larynx

function: elastic cartilage tissue

provides strength, and elasticity, and maintains the shape of certain structure such as the external ear.

Location: Elastic cartilage tissue

external ear (helix), epiglottis

Function: Fibrocartilage

Acts as shock absorbers; cartilage that contains fibrous bundles of collagen

location: Fibrocartilage tissue

intervertebral discs; pubic symphysis

Function: Bones (osseous tissue)

bone supports and protects (by enclosing); provides levers for the muscles to act on; stores calcium and other minerals and fat; marrow inside bones is the site for blood cell formation (hematopoiesis)

Location: Osseous tissue

Bones

Function: Blood

Transportation materials to and from cells Transports nutrients, carries O2, waste products, and other substances

Location: Blood

contained within blood vessels

Function: Skeletal muscle

voluntary movement; locomotion; manipulation of the environment; facial expression; voluntary control

Location: Skeletal muscle

In the skeletal muscles attached to bones or occasionally to skin

Function: Smooth muscle

propels substances or objects along internal passageways; involuntary control

Location: Smooth muscle

Mostly in the walls of hollow organs

Function: Cardiac muscle

as it contracts, it propels blood into the circulation; involuntary control

Location: Cardiac muscle

walls of the heart

Function: Nervous tissue

neurons transmit electrical signals from sensory receptors and to effectors (muscles and glands); supporting cells support and protect neurons

Location: Nervous tissue

brain, spinal cord, nerves
