Tissue

Tissue: Cells that are organized into groups and layers

Tissue Tissue: Cells that are organized into groups and layers 4 Kinds: Epithelial, Connective, Muscle, Nervous

Tissue Tissue: Cells that are organized into groups and layers 4 Kinds: Epithelial, Connective, Muscle, Nervous Basement Membrane: Underside of tissue, nonliving layer

Tissue Epithelial Tissue: Tissue that covers body surface, organs, and glands.

Tissue Epithelial Tissue: Tissue that covers body surface, organs, and glands. Used for protection, secretion, absorption, and excretion

Tissue Epithelial Tissue: Tissue that covers body surface, organs, and glands. Used for protection, secretion, absorption, and excretion Lack blood vessels, divide frequently, tightly packed

Simple Squamous Epithelium

Consist of a single layer of tightly packed, flattened cells

Simple Squamous Epithelium Consist of a single layer of tightly packed, flattened cells Form in the airs sacs of lungs, blood vessels, and body cavities

Simple Squamous Epithelium Consist of a single layer of tightly packed, flattened cells Form in the airs sacs of lungs, blood vessels, and body cavities Thin and delicate, easily damaged

Simple Cuboidal Epithelium

Cube-shaped cells, tightly packed

Simple Cuboidal Epithelium Cube-shaped cells, tightly packed Ovaries, kidneys, salivary glands, liver

Simple Columnar Epithelium

Elongated, single layer cells.

Simple Columnar Epithelium Elongated, single layer cells. Can contain Cilia: for movement of materials

Simple Columnar Epithelium Elongated, single layer cells. Can contain Cilia: for movement of materials Female reproductive tubes, small and large intestines

Pseudostratified Columnar Epithelium

Single, elongated layer, but appear stratified because nuclei are located at different levels

Pseudostratified Columnar Epithelium Single, elongated layer, but appear stratified because nuclei are located at different levels Line passages of respiratory system, trap dust and microorganisms

Stratified Squamous Epithelium

Many layers, thick tissue. New cells push older ones further out

Stratified Squamous Epithelium Many layers, thick tissue. New cells push older ones further out Outer layer of skin, esophagus, vagina, anal canal

Stratified Cuboidal Epithelium

Two-three layers of cube like cells

Stratified Cuboidal Epithelium Two-three layers of cube like cells Sweat glands, Salivary glands

Stratified Columnar Epithelium

Several layers of elongated cells

Stratified Columnar Epithelium Several layers of elongated cells Male urethra

Transitional Epithelium

Specialized to contract and expand based upon tension

Transitional Epithelium Specialized to contract and expand based upon tension Bladder and ureters

Glandular Epithelium Cells that produce and secrete substances into ducts and body fluids

Glandular Epithelium Cells that produce and secrete substances into ducts and body fluids Exocrine Glands: secrete their product on open surfaces (Skin, digestive tract)

Glandular Epithelium Cells that produce and secrete substances into ducts and body fluids Exocrine Glands: secrete their product on open surfaces (Skin, digestive tract) Endocrine Glands: Secrete into tissue fluid and blood

Tissue Illustration Draw and illustrate the 8 types of specific tissue Label: Nucleus, Cytoplasm, Basement membrane, and Connective Tissue Two types of tissue per page, Use Color!!! Describe cell and give examples of type Use pg in Text
