1. Lab 11: Mammalian Organ Systems II – Respiratory and Circulatory Systems

2. Work with same partner as last week Use the same rat as last week (if you can’t find it, get help from a TA) If you don’t have a partner, let a TA know Follow lab manual directions for opening the chest cavity (cut up along sternum towards the head) Task A-1:Rat respiratory system Task B-2:Rat circulatory system

3. See exit activity (in your lab manual); quiz each other on structures Use the figures in your lab manual to help you! Don’t destroy structures! Task A-1:Rat respiratory system Task B-2:Rat circulatory system

4. don’t worry about all of the arteries and veins that are in your manual – just those on the exit activity the iliac arteries become the femoral arteries – just learn them as a the iliac/femoral arteries latex colors: yellow – hepatic portal system red – arteries to most of body; pulmonary veins blue – veins from most of body; pulmonary arteries SOMETIMES these are not done correctly Task A-1:Rat respiratory system Task B-2:Rat circulatory system

5. Use tubes to help you get a sense of the flow of blood through the heart Learn the order of blood flow into, through, and out of the heart – including structure names (blood vessels, heart chambers, and valves) Task B-1:Bovine (cow) heart

7. Don’t forget the slide this week! use Figure 11-8 to help you be able to identify each of these cell types (this makes an excellent slide question or two for the practical) “red blood cells” may have the red color faded out; go more by shape than by color Task C-1:Blood smear slide

8. You will likely have some extra time after completing the activities for today’s lab; take advantage of it for review!!! plenty of review material is available for all labs all the stuff you need for last week’s lab is out in case you did not finish also…
