study of tissues
Define: tissue
collections of cells that have a similar or common function
Stratified epithelial is usually found in
High abrasion areas such as skin and lining of the mouth
Simple epithelial is usually found
Passage or filtration occurs and little protection is needed
4 main types of tissues
connective, epithelium, muscle, nervous
Tissues come together collectively to form___
organs
This tissue forms boundaries between different environments; protects, secrets, absorbs, filters
epithelial tissue
This tissue contracts to cause movement
muscle tissue
This tissue is responsible for internal communication and is located in the brain, spinal cord, and nerves
nervous tissue
This tissue supports, protects, binds other tissues together
connective tissue
This is the most abundant tissue in the body
Connective
