  1. Hemangiosarcoma
    • A generally aggressive malignant tumor that originates from the blood vessels in various parts of the body.
    • Most common in the large breed dogs.
    • Mostly associated with spleen and/or liver. Some with heart.
    • Clinical signs: internal bleeding. Anemia and shock, acute weakness, collapse, difficulty breathing.
  2. Giraffe physiology
    • They have giraffe physiologic hypertension due to their extraordinary height. They are not born hypertensive, but become so as they grow.
    • The left ventricular and interventrical walls are hypertrophied and their thicknesses are linearly related to neck length. Cardiac output is the same but peripheral resistance is double that predicted for similar sized mammals.
  3. Rete mirabile
    • Complex of arteries and veins lying very close to each other.
    • Used for heat exchange in feet, fluid and electrolyte exchange in kidneys.
    • Used to equalize blood pressure in the giraffe's head when drinking.
  4. Image Upload
    Where is this found? What things are shown here?
    • This is from the liver.
    • You can see the hepatocytes.
    • Also, the dark blue cells are called Kupffer cells.
    • The hepatocytes make contact with sinusoids, which are vascular channels lined with highly fenestrated endothelial cells.
  5. Image Upload
    Where is this found? What things are shown here?
    • This is from the pancreas.
    • There is an exocrine pancreatic duct in the box.
  6. Image Upload
    This is the pancreas. What is shown in the boxes?
    • Pancreatic islets. AKA islets of Langerhans.
    • These are the regions of the pancreas that contain its endocrine (hormone-producing) cells.
  7. Image Upload
    What are these? Where can they be found?
    • Sebaceous glands.
    • Can be found in the skin.
    • They secrete sebum, to lubricate the skin and hair of mammals.
  8. Image Upload
    In this skin sample, what is there alot of?
  9. What can be used to stain mast cells?
    Toluene blue.
  10. Image Upload
    What would you classify the epithelium as?
    Pseudostratified ciliated columnar epithelium.
  11. Image Upload
    What are these?
    • Left: arteriole.
    • Right: venule.
  12. Image Upload
    Just look at the difference between a medium muscular artery, a small artery, an arteriole, and a venule.
  13. Image Upload
    What two things are shown here?
    Medium muscular artery and a medium vein.
  14. Image Upload
    What are the things shown at the bottom?
    Purkinje fibers.
