Question

What is the difference between simple columnar epithelium tissue and compound columnar ephithellium tissue​

Answer 1

Answer:

Complete answer: The simple epithelium consists of only a single layer of cells that lie on a basement membrane. ... The compound epithelium has more than one layer of epithelial cells, and they are present on surfaces where the chances of wear and tear are high.

Answer 2

Answer:

The difference between simple epithelium and compound epithelium are given below:

Simple Epithelium Compound Epithelium

1. A single layer of epithelial cells resting on a basement membrane are called as simple epithelium.

2. They are present in the secretory and absorptive surface.

3. It is not protective as it can't resist the damages due to mechanical or chemical abrasions.

4. Squamous, cubical, columnar epithelium, etc.

Compound Epithelium

1. It consists of more than one layer. The innermost layer of cells is arranged on the basement membrane.

2. They are not involved in secretory or absorptive functions.

3. Because of the multi-layered structure, they help in the protection of tissues below them.

4. They may be transitional or stratified, i.e., stratified squamous epithelial.
