We did the EKG lab in class (handout provided before vacation). You will have about 10 minutes to complete your group work at the beginning of class Wednesday. The new PPT (on blood) is now posted on the class website.
Homework: read pages 645-648 and do #1,2,3 page 644

Period 2:
We talked about the digestive system using one of our notes handouts. Topics covered include the anatomy of the system, how each part works together to digest food (specific function of each part) and the differences between chemical and mechanical digestion.
Homework: quiz tomorrow on the digestive system!

Period 5:
We finished talking about the heartbeat, using the PPT notes. We outlined the autorhythmic cells in the heart and talked about some problems with the heartbeat, including methods of fixing these problems.
Homework: same as period 1, due Wednesday

Period 6:
We used a notes packet to go over the respiratory system. We talked about the anatomy of the system (tracing the path of air through the nose and down to the lungs) and the specific function of alveoli in gas exchange. We also discussed how the diaphragm acts as a muscle in the function of breathing.
Homework: read pages 971-974 and do #1,4 on page 974 AND respiratory system crossword puzzle
