Epithelial tissue
A tissue that covers the surface of the body and lines the ducts, vessels, and other body cavities
Function of epithelial tissue
Protection, absorption, filtration and secretion
What is epithelial tissue made of
Continuous sheets of connected cells
What are the three basic cell shapes
Squamous, cuboidal, and columnar
Epithelial tissue is
Avascular
Simple epithelial tissues have
One cell layer
Functions of simple epithelial tissue cells
Filtration, absorption, and secretion
Stratified epithelium tissue cells have
Two or more cell layers
Functions of stratified cell
Protection
Simple squamous epithelium function and location
Function: filtration
Location: lawn tissue and capillary blood vessels
Simple cuboidal
Function: secretion
Location: kidney tubules and glands
Simple columnar
Function: absorption and secretion
Location: entire digestive tract
Pseudostratified columnar
Function: absorption and secretion
Location: most of the respiratory tract
Simple columnar has
Microvilli
Pseudostratified columnar has
Cilia
Stratified squamous
Most common type of stratified epithelium
Location: esophagus, mouth, and skin
Stratified cuboidal and stratified columnar
Extremely rare
Stratified transitional
Location: in the urinary system, bladder, uterus
Function: allows cells to move so that tissue can stretch
Goblet cells
Cells that make and secrete mucus protein
Goblet cells are in what tissues
Simple columnar, pseudostratified columnar
Connective tissue
Connects different body parts: most abundant tissue
Connective tissue functions
Protecting, supporting, and binding together body tissues
General structure of connective tissue
- Vascular (good blood supply)
2. Surrounded by ECM
Structure of the ECM
Ground substance composed mainly of water plus proteins and polysaccharides.
(Collagen and elastin)
