Lab 11: Lab 11: Mammalian Organ Systems II Mammalian Organ Systems II
– Respiratory and – Respiratory and Circulatory SystemsCirculatory Systems
• 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 systemTask B-2: Rat circulatory system
• 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 systemTask B-2: Rat circulatory system
• 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 systemTask B-2: Rat circulatory system
• 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
• 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
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
