Simple means that there’s only one layer of the cells, not as much protection as stratified which indicates several layers of the cells. Stratified epithelium are named according to the cells at the apical surface of the epithelium membrane.

Question 23

Question 24

What role does ciliated epithelium play?

Answer 24

They keep mucus and any other debris’s from entering the lower reaches of lung tissue

Question 25

How does transitional epithelium differ from other stratified squamous epithelium?

Answer 25

It's structure is different in that it is rounded or plump

Question 26

How does the structural difference in transitional epithelium and stratified squamous epithelium support its function?

Answer 26

Transitional epithelium has the ability to slide over one another to allow the organ to be stretched

Question 27

How did the endocrine and exocrine glands different and structure and function?

Answer 27

Endocrine glands are ductless, and their function is to release hormones into the extracellular fluid where they enter the bloodstream lymphatic vessels. Exocrine glands have ducts and they secrete through the ducts to an epithelial surface

Question 49

Why do adipose cells remind people of a ring with a single jewel?

Answer 49
