• Human/Cat Gross AnatomyHistology

Objectives for Lab 4

• 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.

3
Objectives for Lab 5

• 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.

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.

Descending and Thoracic Aorta
Diaphragm is the point at which the thoracic
aorta becomes the abdominal aorta

Cat Blood Vessel Dissection Schedule

• Blood vessel labs
• Dissection 1(1st lab two weeks ago - arteries
  above diaphragm and upper limb)
• Preparing the cat (see page 721 in Marieb)
• Cardiovascular (pp. 725-728 in Marieb)
• Dissection 2 Combined Labs 4 5
• Lab 4 - arteries below diaphragm and lower limbs
• Lab 5 - all veins

17
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

18
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 artery in slide 31-4094 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
  Labs 4 AND 5 (arteries below diaphragmlower limb
  veins). See Mariebs Lab manual pp. 725-733
  for instructions.
• Review human arteries and veins listed for Lab
  4/5
• Complete Lab 4 5 Assignments on a separate
  sheet of paper, put your name on it, and hand it
  in today or next week.
