Objectives for Lab 5

• Identify the veins listed below in a human model
  or photograph of a human.
• Identify the veins listed below on a dissected
  cat or photograph of a cat.
• Describe the layers/tunics and histological
  characteristics of veins.
• Trace the path of a drop of blood through the
  arteries AND veins, including the heart and
  pulmonary circulation.

13
Comparison of Walls of Arteries and Veins
Smooth muscle of the tunica media in both
arteries and veins is innervated by the
sympathetic nervous system.

Cat Blood Vessel Dissection Schedule

• Blood vessel labs
• Dissection 1(1st lab - arteries above diaphragm
  and upper limb)
• Preparing the cat (see page 706 in Marieb)
• Cardiovascular (pp. 733-741 in Marieb)
• Dissection 2 (last lab - arteries below diaphragm
  and lower limbs)
• Arteries below diaphragm (see Marieb)
• Dissection 3 (today - all veins review arteries)
• Veins (see Marieb)

23
Reminders for Cat Dissection

• You must wear gloves and goggles for this lab!
• ABSOLUTELY NO FOOD OR DRINK
• Be EXTREMELY careful when using the scalpels
• Keep your index finger on the top of the blade
• Be careful not to inadvertently cut structures
• Use a blunt probe, or your gloved fingers to
  dissect away tissue. Use the scalpel ONLY for
  initial cutting. Proceed S-L-O-W-L-Y.
• Discard scraps/liquid into the appropriate
  container
• Gloves, paper towels, plastic bags -gt regular
  trash

24
Continuing with Cat Dissection

• Work in groups you formed for dissection of
  arteries
• Get some paper towels and keep them at your lab
  table
• Get your instruments and dissecting tray (large
  trays in the front of the lab) ready
• Get a cat and cut open the sealed bag but dont
  discard the fluid youll be using this cat all
  semester and replacing the fluid each time.
• Let the cat out of the bag - again! ?
• You should be able to locate all the veins listed
  in your Lab Guide

Things you should do in lab today

• Examine the vein slide under the microscope
• Name/identify the layers of the vein
• Describe how each layer (tunic) is constructed
• Refer to Mariebs Lab Manual Figure 32.2 right
  side
• Perform cat dissection of veins listed for Lab 5.
  See Mariebs Lab manual pp. 737-741 for
  instructions.
• Review human veins listed for Lab 5
• Complete Lab 5 Assignment on a separate sheet of
  paper, put your name on it, and hand it in today.
• Use figures 32.8 32.15 as a guide
