Q

What is the location, structure and function of simple squamous epithelium tissue?

A

Simple - 1 layer
Located in lungs, lining of blood vessels and the heart
Function: easy gas exchange

17
Q

What is the location, structure and function of simple cuboidal epithelium tissue?

A

Simple 1 layer, cube/square
Located in glands and lining of bronchioles
Function is to secrete and to move mucus out of the bronchioles

18
Q

What is the location, structure and function of stratified squamous epithelium tissues?

A

Several layers
Located in skin
Function is protection

19
Q

What is the structure, function and location of stratified cuboidal epithelium?

A

2-3 layers, ring like shape
Location: sweat glands and salivary glands
Function: Secretion, absorption, protection against infection

20
Q

What is the structure, location and function of simple columnar epithelium tissue?

A

Structure: single layer of tall columns
Location intestines and stomach
Function: absorption

21
Q

What is the structure, location and function of stratified columnar epithelium tissue?

A

*most rare
2 layers
Location: larynx
Function: protection, secretion

22
Q

What is the location, structure and function of pseudostratified ciliated columnar epithelium tissue?

A

Location lining of the nasal cavity, trachea, nasal sinus
Structure: disorganized
Function: Secretes/ move mucus

23
Q

What is the structure, location and function of transitional epithelium tissue?

A

Location: bladder
Function: accommodates fluctuations in the volume of fluid
Structure: The number of layers is based on if it’s stretched or not stretched

24
