I’ve decided from here on out to include the slides and the handout in the same post. Below you will find both the slides and the handout for the chapter on Protection, Support and Locomotion, dealing with the skin, skeletal system, and muscular system. I go into the structure and functions of all three, and get into some of the exciting details of how the skin is involved in temperature regulation, how the skeletal system is there for our protection and how muscle contraction actually happens.
These are all from Chapter 34 in Biology: The Dynamics of Life.
Wonderful videos and powerpoint slides. Keep up the good work.
