Is found on the outer and inner body and organs
What is the Epithelial Tissue function?
secrete, absorbs, and protect
What is a tissue?
Cells that are organized in a similar structure or function
What is an organ?
A structure with a specific function and is composed of two or more tissues
What is an organ system?
When multiple organs are used to work together for a common purpose
What is histology?
The study of tissues
What is the lumen?
The cavity or space in an organ
What does the word simple mean in tissue definition?
One uniform cell layer thick
What is stratified?
When something is multiple cells thick
What is pseudostratified?
A single layer of cells but looks like it has multiple layers
What is cilia?
Hairlike projections of the plasma membrane.
What is the function of cilia?
To move things past cells
What is squamous mean?
A flat or pancake like cell
What is the basement membrane?
It is a thin sheet of protein that attaches epithelium tissues with other tissues
What is cuboidal mean?
cube shape cells
What is columnar mean?
Tall in a column or upright position
What is simple squamous epithelium?
It is a one layer thick cell that is flat
Where can simple squamous epithelium be located?
the thoracic or lung cavity, the peritoneum, lining of the abdominal cavity, or pericardial sac
What is simple cuboidal epithelium?
it is one cell layer thick and has a cube like shape.
Where can simple cuboidal epithelium be located?
Salivary glands, thyroid, pancreas
What does simple cuboidal epithelium specialize in?
secretions
What is Simple Columnar Epithelium?
They are one cell layer thick and have column like cells
Where is Simple Columnar Epithelium located?
stomach or digestive tract
What does Simple Columnar Epithelium specialize in?
absorption and secretions
What is simple columnar ciliated epithelium?
Has a one cell layer thick, has column shape cells, and has hair like cells.
Where is the simple columnar ciliated epithelium located?
uterus or respiratory tract or oviducts
What does simple columnar ciliated epithelium do?
can move eggs out of reproductive tract and foreign particles out of the respiratory tract. TO SUM UP JUST MOVES THINGS PAST THE CELL
What is stratified squamous epithelium?
has multiple layers of cells and has flat like cells
Where is stratified squamous epithelium located?
skin, cheek and gum, vagina, cornea of eye
What is stratified squamous epithelium specialize?
dead cells that protect the living cells
What is Pseudostratified Ciliated Columnar Epithelium?
It is a one cell layer, that have hair like cells, has a column shape like cells, and has a goblet cell
What is Pseudostratified Ciliated Columnar Epithelium located?
It is located in the respiratory tract
What is the function of a goblet cell?
It secretes mucus
What type of cell is this?
Simple squamous epthelium
What is this circled?
the nucleus
What is the arrow pointing at?
the plasma membrane
What is the arrow pointing at?
The cytoplasm
