Characteristics of simple squamous epithelial tissue:
- A single later of flat cells that contain a disc-shaped nucleus. They are used in functions such a diffusion and filtration.
Examples of simple squamous epithelial tissue:
- This type of tissue is found in kidney glomeruli, the lining of the heart, blood vessels, and lymphatic vessels.

2. Simple Cuboidal Epithelium
Characteristics of simple cuboidal epithelial tissue:
- A single layer of cube-like cells that have a large spherical nuclei. Their function is secretion and absorption.
Examples of simple cuboidal epithelial tissue:
- Cuboidal epithelium is found in kidney tubules, ducts and secretory portions of small glands, and ovary surface.

3. Simple Columnar Epithelium
Characteristics of simple columnar epithelial tissue:
- A single layer of tall cells that contain an oval nuclei. These types of cells can contain cilia. They are used in absorption and secretion.
Examples of simple columnar epithelial tissue:
- Ciliated columnar epithelium lines the small bronchi, uterine tubes, and some regions of the uterus. Non-ciliated columnar epithelium is lines the digestive tract and gallbladder.

4. Pseudostratified Columnar Epithelium
Characteristics of pseudostratified columnar epithelial tissue:
- A single layer of cells with differing heights. They can be either ciliated or non-ciliated. Their function is secretion and propulsion of mucus.
Examples of pseudostratified columnar epithelial tissue:
- Ciliated pseudostratified columnar epithelium is found in the trachea, while non-ciliated is found in the male sperm-carrying ducts.

5. Stratified Squamous Epithelium
- A thick membrane composed of several layers of cells. Their function is to protect the underlying areas that are subjected to abrasion.
Examples of stratified squamous epithelial tissues:
- Stratified squamous epithelial tissue is found in the external part of the skin’s epidermis (keratinized cells) and linings of the esophagus, mouth and vagina (non-keratinized cells).

6. Stratified Cuboidal Epithelium
Characteristics of stratified cuboidal epithelial tissues:
- This type of tissue is very rare in the body, but when found is usually two cell layers thick.
Examples of stratified cuboidal epithelial tissues:
- This tissues are found in some sweat and mammary glands.

7. Stratified Columnar Epithelium
Characteristics of stratified columnar epithelial tissue:
- This type of tissue is had limited distribution in the body and is usually occurs at a transition area between two other types of epithelia.
Examples of stratified columnar epithelial tissue:
- Stratified columnar tissue is found in the pharynx, male urethra, and the lining of some glandular ducts.

8. Transitional Epithelium
Characteristics of transitional epithelial tissues:
- Transitional epithelium is a layer of several cells, with basal cells being cubiodal and surface cells being dome shaped.
Examples of transitional epithelial tissues:
- Transitional epithelium lines the urinary bladder, ureters, and part of the urethra.
