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

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.

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
