Biology 102 Laboratory 4 Arteries II Human/Cat Gross Anatomy Histology

1. Biology 102 Laboratory 4 Arteries II Human/Cat Gross AnatomyHistology

2. 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.

3. Review of last lab’s vessels

4. Review of last lab’s vessels

5. Review of last lab’s vessels

6. Review of last lab’s vessels

7. Major Vessels of Arterial System • Reminders: • Arteries carry blood AWAY from heart. • Same ‘tube’ is named something different depending on the anatomical landmark it’s near. Figure from: Martini, Anatomy & Physiology, Prentice Hall, 2001

8. Descending and Thoracic Aorta Diaphragm is the point at which the thoracic aorta becomes the abdominal aorta Figure from: Martini, Anatomy & Physiology, Prentice Hall, 2001

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

16. 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 -> regular trash

17. 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 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 arteries below the diaphragm and in the lower limb that are listed in your Lab Guide

24. Descending aorta Right iliolumbar artery Left iliolumbar artery Left internal iliac artery Right internal iliac artery Right external iliac artery Left external iliac artery Left deep femoral artery Left femoral artery Right femoral artery Median sacral artery

25. Things you should do in lab today • Examine the artery slide under the microscope (if you haven’t already done this) • Name/identify the layers of the artery • Describe how each layer (tunic) is constructed • Refer to Marieb’s Lab Manual Figure 32.1 left side • Perform cat dissection of arteries listed for Lab 3 (below diaphragm and lower limb). See Marieb’s Lab manual pp. 733-741for 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.

26. 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 we’ll be covering.
