Tissue Functions And Locations

Front 1

Simple Squamous Epithelium

Back 1

Function: Allows passage of materials by diffusion and filtration in sites where protection is not important;secretes lubricating substances in serosae.
Location: Kidney glomeruli; air sacs of the lungs; lining of heart; blood vessels, and lymphatic vessels; lining of ventral body cavity(serosae)

Front 2

Simple Cuboidal Epithelium

Back 2

Function: Secretion and absorption.
Location: Kidney tubules; ducts and secretory portions of small glands; ovary surface.

Front 3

Simple Columnar Epithelium

Back 3

Function: Absorption; Secretion of mucus, enzymes, and other substances; ciliated type propels mucus (or reproductive cells).
Location: Nonciliated type lines most of teh 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.

Front 4

Pseudostratified Columnar Epithelium

Back 4

Function: Secretion, particularly of mucus; proplusion 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.

Front 5

Transitional Epithelium

Back 5

Function: Stretches readily and permits distension of urinary organ by contained urine.
Location: lines the ureters, bladder, and part of the urethra.

Front 6

Stratified Squamous Epithelium

Back 6

Function: Protects underlying tissues in areas subjected to abrasion.
Location: nonkeratinized type forms the most linings of the esophagus, mouth, and vagina; keratinized variety forms the epidermis of the skin.

Front 7

Stratified Cuboidal Epithelium

Back 7

Function: Protection
Location: Largest ducts of sweat glands, mammary glands, and salivary glands.

Front 8

Stratified Columnar Epithelium

Back 8

Function: Protection; secretion.
Location: Rare in the body; small amounts in male urethra and in large ducts of some glands.

Front 9

Mesenchyme

Back 9

Function: Gives rise to all other connective tissue.
Location: Primarily in embryo.

Front 10

CT Proper: Loose Connective Tissue
Areolar
Fibrocyte

Back 10

Function:Wraps and cushions organs; its macrophages phagocytize bacteria; plays important role in inflammation; holds and conveys tissue fluid.
Location: Widely distributed under epithelia of the body (forms lamina propria of mucousmembrans); packages organs; surrounds capillaries.

Front 11

CT Proper: Loose Connective Tissue
Reticular
Fibrocyte

Back 11

Function: Fibers form a soft internal skeleton (stroma) that supports other cell types including white blood cells, mast cells, and marcophages.
Location: Lymphoid organs (lymph nodes, bone marrow, and spleen).

Front 12

CT Proper: Loose Connective Tissue
Adipose
Fibrocyte

Back 12

Function: Provides reserve food fuel; insulates against heat loss; supports and protects organs.
Location: Under skin; around kidneys and eyeballs; within abdomen; in breasts.

Front 13

CT Proper: Dense Connective Tissue
Regular
Fibrocyte

Back 13

Function: Attaches muscles to bones or to muscles; attaches bones to bones; withstands great tensile stress when pulling force is applied in one direction.
Location: Tendons, most ligaments; aponueroses.

Front 14

CT Proper: Dense Connective Tissue
Irregular
Fibrocyte

Back 14

Function: Able to withstand tension exerted in many directions; provides structural strength.
Location: Dermis of teh skin; submucousa of digestive tract; fibrous capsules of organs and joints.

Front 15

Cartilage: Hyaline
Chondrocyte

Back 15

Function: Supports and reinforces; has resilient cushioning properties; resists compressive stress.
Location: Forms most of the embryonic skeleton; covers the ends of long bones in joint cavities; forms costal cartilages of the ribs; cartilages of the nose, trachea, and larynx.

Front 16

Cartilage: Elastic
Chondrocyte

Back 16

Function: Maintains the shape of the structure while allowing great flexibility.
Location: Supports the external ear(pinna); Epiglottis.

Front 17

Cartilage: Fibrocartilage
Chondrocyte

Back 17

Function: Tensile strength with the ability to absorb compressive shock.
Location: Intervertebral discs of knee joint.

Front 18

Bone (osseous tissue)
Osteocyte

Back 18

Function: Bone supports and protects (by enclosing); provides levers for the muscles to act on; Sores calcium and other minerals and fat; marrow inside bones is the site for blood formation.
Location: Bones

Front 19

Blood
Hematopoietic Stem Cell

Back 19

Function: Transports respiratory gases, nutrients, wastes and other substances.
Location: Contained within blood vessels.

Front 20

Skeletal Muscle

Back 20

Function: Voluntary movement; locomotion; manipulation of the environment; facial expression; Voluntary control
Location: In skeletal muscles attached to bones or occasionally the skin.

Front 21

Cardiac Muscle

Back 21

Function: As it contracts, it propels blood into circulation; involuntary control.
Location: Walls of heart.

Front 22

Smooth Muscle

Back 22

Function: Propels substances or objects (food, urine, a baby) along internal passageways; involuntary control
Location: Mostly in the walls of hollow organs.

Front 23

Nervous tissue

Back 23

Function: Transmit electrical signals from sensory receptors and to effector (muscles and glands); control effector activity
Location: Brain, spinal cord, and nerves.
