A group of cells similar in structure and function. 1. Define tissue. _______________________________________________________________________________________ __________________________________________________________________________________________________ 2. Use the key choices to identify the major tissue types described below. Key: a. b c c, d a b d c b a a a d connective tissue b. epithelium c. muscle d. nervous tissue
1. lines body cavities and covers the body’s external surface 2. pumps blood, flushes urine out of the body, allows one to swing a bat 3. transmits electrochemical impulses 4. anchors, packages, and supports body organs 5. cells may absorb, secrete, and filter 6. most involved in regulating and controlling body functions 7. major function is to contract 8. synthesizes hormones 9. the most durable tissue type 10. abundant nonliving extracellular matrix 11. most widespread tissue in the body 12. forms nerves and the brain
