Where would you find Simple Cuboidal epithelial tissue?
Glands & their ducts.
Forms walls of kidney tubules.
Covers the ovaries & vasdeferans.
Describe Simple columnar epithelial tissue;
Single layer of tall cells.
(Often includes Goblet cells, which produce mucus.)
Where would you find Simple columnar epithelial tissue?
Linning digestive tract.(cellia)
Describe Pseudostratified epithelial tissue;
Single layer but appears to be >1 layer because some cells are shorter than others.
Sometimes ciliated (the respiratory tract; it helps to move mucus out of airways)

Found in the reproductive system.
Stratified cuboidal & Columnar epithelial tissue / where?
Rare in human body
Found mainly in ducts of large glands.
Describe Transitional Epithelium & where is it found?
It can easily change shape, the shape depends upon the amount of stretching.
It line organs of the urinary system.
Describe Glandular Epithelium & where is it found?
One or more cells that secretes a particular product. It is found in 2 major gland types;
Endocrine gland-(hormone secretion) ductless
Exocrine gland-Empty through ducts to the epithelial surface (includes sweat & oil glands)
Where is connective tissue found?
Everywhere in the body.
Includes most abundant & widely distributed tissues.
What are the functions of connective tissue?
Binds body tissues together
Gives support
Provides protection
What are the characteristics of connective tissue?
Some tissue types are well vascularized.
Some have poor blood supply (avascular)
