Objectives for Lab 4

• Identify the arteries below the diaphragm and in
  the lower limb listed on your Lab Handout in a
  human model or photograph of a human.
• Identify the arteries below the diaphragm and in
  the lower limb listed on your Lab Handout on a
  dissected cat or photograph of a cat.
• Be able to trace the path of a drop of blood
  through the arteries for today.

Major Vessels of Arterial System

• Reminders
• Arteries carry blood AWAY from heart.
• Same tube is named something different
  depending on the anatomical landmark its near.

Cat Blood Vessel Dissection Schedule

• Blood vessel labs
• Dissection 1(last lab - arteries above diaphragm
  and upper limb)
• Preparing the cat (see page 721 in Marieb)
• Cardiovascular (pp. 725-728 in Marieb)
• Dissection 2 (today- arteries below diaphragm and
  lower limbs)
• Cardiovascular (pp. 725-728 in Marieb)
• Dissection 3 (next lab - all veins)
• Cardiovascular (pp. 729-732 in Marieb)

15
Reminders for Cat Dissection

• You must wear lab coat, 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

16
Continuing with Cat Dissection

• Work in groups you formed for dissection of
  arteries last lab
• 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 arteries
  below the diaphragm and in the lower limb that
  are listed in your Lab Guide

Things you should do in lab today

• Examine the artery slide under the microscope (if
  you havent already done this)
• Name/identify the layers of the artery
• Describe how each layer (tunic) is constructed
• Refer to Mariebs Lab Manual Figure 32.1 left
  side
• Perform cat dissection of arteries listed for Lab
  3 (below diaphragm and lower limb). See Mariebs
  Lab manual pp. 721 and 725-728 for instructions.
• Review human arteries listed for Lab 4 (below
  diaphragm and lower limb)
• Complete Lab 4 Assignment on a separate sheet of
  paper, put your name on it, and hand it in today.

25
Next Lab

• We will continue with blood vessels by looking at
  all the veins in the next lab
• Good idea to look ahead at the veins well be
  covering.
