Types of tissue
Epithelial, Connective, Muscular, and nervous tissue.
The cells in this tissue are usually thin, functions are diffusion of gases across linings and the gases best diffuse across thin moist surfaces.
The picture below describes the location of the Epithelial tissue.
Composed of minerals and organic matter, Main function is strength and flexibility, strength is provided by minerals, flexibility by organic matter. Picture below showing the locations and functions. http://cnx.org/contents/4e46e67c-5867-4d6b-8583-fa0bba6d65af@1
Contains fibres, main function pumping by contraction, fibres ratchet past each other to contract the muscle. Picture below showing function and location.
Structure long thin, insulated fibres, functions include carrying electrical messages from eye to brain. Long and insulated so electrical messages are carried quickly. Picture below showing location.
