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.

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 -> 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 don’t discard the
fluid; you’ll 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

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 Marieb’s Lab Manual Figure 32.2 right side
• Perform cat dissection of veins listed for Lab 5. See Marieb’s 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

Next Lab…
• Blood Pressure
– Read ahead: Exercise 33 in Marieb’s Lab Manual
– Review the handout (available online)
• ECG (EKG)
– Read ahead: Exercise 31 in Marieb’s Lab Manual
– Review the handout (available online – same one as
for BP)
• Wear comfortable clothes/shoes since you’ll be
exercising!
