How many types of tissues are there?
There are four types of tissues
Name the four different types of tissues.
Epithelial
Connective
Muscular
Nervous
What is the role of epithelial tissue?
Forms barriers/linings and coverings
What are the two main roles of connective tissue?
Provide structure and support
Link and protect organs
What are the two main roles of muscular tissue?
Contract to move
Create force
What are the two main roles of the nervous tissue?
Control
Communication
How are epithelial or connective tissues classified?
By morphology
What types of tissues are classified through morphology?
Epithelial tissue
Connective tissue
How are muscular or nervous tissues classified?
Muscular and nervous tissue are classified based on the function e.g. muscle tissues have to create force
List some examples of epithelial tissue.

Lining of body cavities
What type of specialised cell is included under the epithelial classification?
Secretary cells and glands
List the four functions of epithelial tissue.
Physical protection
Control permeability
Provide sensation
Produce specialized secretions
What three epithelial tissues found in the body provide physical protection?
Outer layer of skin
Lining of the gut
Respiratory tract
Describe how epithelial tissue controls permeability.
They allow water, gases and nutrients to cross into and out of the body
They prevent toxins and micro organisms from entering
