We'll have a quiz on Thursday instead of Tuesday this week. It will be over Hormones (old material), Metabolism (current material), and Circulatory (new material).

Mini-Lecture
- open vs. closed circulatory system, and why these different circulatory systems evolved. - how the electrical activity of heart muscles is different than in skeletal muscles (such as your bicep). - Different ways in which your heart and circulatory system maintain homeostasis, with respect to delivering oxygen to your body and removing carbon dioxide, and with resepct to keeping the blood pressure stable during different body orientations or thoracic pressure levels.
