Wow, another snow day! Your respiratory system will now be on Monday, and your lung volume lab will be due then....assuming we have school! It should be warming up by then, so these lake effect snow squalls will likely end.
If you were absent on Thursday, but have your textbook at home with you, please read the first 2 sections in the Transport and Circulation chapter (pages 280 -291). You should define the following terms: vascular system, circulatory system, cardiovascular system, open transport system and closed transport system. From the second section, define cardiac circulation, pulmonary circulation, and systemic ciruculation. What are the 3 elements of any circulatory system? In which of the 3 circulatory systems is most of your blood right now? How is an arteriole different from an artery? How is a venule different from a vein? Finally, write a summary of the anatomical features and functions of arteries, veins, and capillaries.
Enjoy your extra long weekend!
