It is quite interesting how digestion and circulation and respiration and excretion all work together! We need to break down food, bring in oxygen, transport both to cells so they can release energy, and then clean up the waste so we don't die! Pretty neat plan!!! This weekend most of us have quite a bit of work to do. Set the kitchen timer for 30 minutes... watch the video for digestion and check packet work... then take a short break and assess if you need more time... keep working through the videos and systems (some of you may choose to do a little research work for answers!). We will discuss the Excretory System together on Monday as well as check with questions you may still have. Packets are due Monday (or Tuesday if the weekend didn't allow much work time). IF YOU MISSED CLASS TODAY get working! You still can learn about your body if you do the work!
