Tissue Types and Their Functions

Smooth Muscle

Involuntarily moves substances through intestines

Cardiac Muscle

Involuntarily contracts, circulating blood

Skeletal Muscle

Voluntary movement of bones

Nervous Tissue

Transmits communications through electrical signals

Blood

Transports gases and nutrients

Bone

Supports against the pull of gravity

Fibrocartilage

Padding or cushioning; absorbs shock

Elastic Cartilage

Maintains the shape of a structure while still flexible

Hyaline Cartilage

Supports; prevents bone from rubbing bone

Dense Irregular Connective Tissue

Gives strength in more than one direction

Yellow Elastic Connective Tissue

Allows tissues to go back to original shape after stretching

White Fibrous Connective Tissue

Connects muscle to muscle or muscle to bone

Reticular Connective Tissue

Provides framework for white blood cells to attach to lymph nodes

Adipose Connective Tissue

Stores fat to use for energy; insulates against heat loss

Areolar (Loose) Connective Tissue

Wraps and cushions organs; holds and conveys tissue fluid

Transitional Epithelium

Stretches to permit bladder to hold more urine

Stratified Squamous Epithelium

Protects underyling tissues against abrasion

Pseudostratified Columnar Epithelium

Secretes mucus and propels mucus with cilia

Simple Columnar Epithelium

Secretion of mucus and enzymes; ciliated type propels mucus

Simple Cuboidal Epithelium

Secretion and absorption

Simple Squamous Epithelium

Allows passages of materials by diffusion and filtration
