dermis
Can you match these structures, functions, and examples with the appropriate type of animal tissue?
epithelial tissue tissue type: epidermis of skin function of tissue: lines organs and body cavities; functions in protection, absorption, and exchange structure of tissue: sheet of tightly packed cells; one or several cell layers thick connective tissue tissue type: bone function of tissue: binds and supports other tissues structure of tissue: sparse population of cells in an extracellular matrix muscle tissue tissue type: skeletal, smooth or cardiac function of tissue: moves body parts structure of tissue: cells called fibers containing contractile proteins nervous tissue tissue type: brain and spinal cord function of tissue: senses stimuli and transmits signals throughout body structure of tissue: neurons with branching extensions
The diagram shows examples of different types of epithelial tissues. The letters in the first column of the table refer to the lettered tissues in the diagram above. Use the diagram to help you fill in the table. Use only pink labels for pink targets and blue labels for blue targets.
