Integumentary Structures Objectives

  • Describe the major structures of the integumentary system including cells and their products.

  • List the various functions of the integumentary system.

  • Explain how the integumentary system relates to thermoregulation.

Warm up:

 

From your notes, what is the difference between an observation and an inference?

This video introduces the integumentary system.

Now that you have background on basic integumentary structures in the skin, this video introduces their functions.

You are not turning in your lecture notes for this guide, there is a different media piece introduced on the next page.  However you will still be able to use your notes for the quiz.

From your lecture notes, name the tissues that make up the epidermis, dermis, and hypodermis of the skin.
