Location

Between bones, inside the heart, lining of hollow organs.

Responds to stimulation and contracts to provide body movement.

Cardiac muscle, skeletal muscle, smooth muscle

In the brain, spinal cord, and nerves

Sends and receives electrical impulses throughout the body to control and coordinate body activity.

Simple squamous

Function

Structure

Location

Absorbs; secretes mucous and enzymes

One layer of columnar cells;
taller than it is wide

Ciliated tissues are in bronchi, uterine tubes, and the uterus;
Smooth (non-ciliated tissues) are in the digestive tract and bladder

Location

One layer of squamous cells; wider than it is tall

Allows materials to pass through by diffusion and filtration; secretes lubricating substances

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

In ducts and secreting portions of small glands and in kidney tubules.

Location

Sweat glands, salivary glands, mammary glands

Protective tissue

The male urethra and the ducts of some glands

Secretes and protects

Several layers of columnar cells;
apical surface covered in cilia

Lines the esophagus, mouth, and vagina

Protects against abrasion

Several layers of squamous cells; cells are flat

Lines bladder, urethra, and ureters

Allows urinary organs to expand and stretch

Several layers of cuboidal cells; neatly arranged

Ciliated tissue lines the trachea and much of the upper respiratory tract

Secretes mucus;
ciliated tissue moves mucus

All cells are irregularly shaped and touch the basement membrane; curvy lateral surfaces;
apical surface covered in cilia

All cells irregularly shaped and arranged

Shared components

Categories

Protein fibers

Ground substance (usually a fluid, but it can also be mineralized and solid, as in bones)

Specialized cells (form immune system)

Fluid connective tissue

Supporting connective tissue

Connective tissue proper

Function

Function

Tissue under the skin, fatty tissue, tendons, and ligaments

Stores energy in adipose tissues until needed

Blood and lymph

Transporting materials from one part of the body to another

Cartilage and bone

Support the body, protect delicate organs, and surround and interconnect other tissues

Absorb shock and bind tissues together

Provide supportive and protective framework for soft organs
