    • E. Aorta and Branches
    • F Pulmonary Veins
  1. What kind of capillaries are these? Name 4 places you can find them? Label.
    • Fenestrated Capillaries for absorption via pinocytosis (pinch off drinking).  Kissable Gentleman Intimately Exfoliate : Kidney Gall bladder, Intestine, Endocrine Glands
    • A: pericyte (contractile cells surrounding endothelial cells of capillaries)
    • B:Basal Lamina
    • C: Fenestrations from Pinocytosis
    • D: Pinocytotic vesicles
    • A: Pinocytotic Vesicles
    • B. Fenestrae
  2. What are these (arrows)? How are they made? What 2 places will you find them and 1 place where you WILL NOT find them?
    Fenestrae enclosed by diaphragms made by glycocalyx pinched off in pinocytosis. Found in intestine & gall bladder for absorption. NOT found in glomeruli of kidney.
  3. Fenestrated capillaries with diaphragms of GI tract& gall bladder @ NO ABSORPTION:
    have ____ walls &   ____ fenestrae and  DURING ABSORPTION ____ walls and ____ fenestrae
    • –during no absorption•have fewer fenestrae•thicker wall–during absorption• During ABSORPTION Increased fenestrae and pinocytotic vesicles•walls thin
  4. Label A, B, C, arrow, arrowhead
    • A Basal Lamina
    • B Endothelium
    • C Podocyte
    • A: Portal Canals
    • B. Central Vein (drains)
    • C. Sinusoids (liver)
    • All are sinusoids in liver!

  5. What kind of cell is this? Label.
    • Discontinuous Capillary (large spaces between endothelial cell)
    • A. RBC
    • B. Endothelial cells
    • C. Discontinuous Gaps between endothelial cells aka space of Disse
    • D. ?? Hepatic cells?
    • H: Hepatocytes (liver cells) with nucleus, mitochondria & organelles
    • S: Endothelial cells and nucleus
    • E: Lumen?
    • D. Space of Disse
    • L?
    • BC?
    • A face liver endothelial cell
    • EV= endothelial pits
    • P= pinocytic openings
  6. B face;  liver endothelial cell;  EV = small dome shaped  hemispheres of pinocytotic vesicles;  arrows show pinocytotic vesicle necks broken so only the rims of the openings remain (arrows)
  7. Label. Also, what is contained in D?
    • A.sinusoids (light pink rows)
    • B. Megakaryocyte (2)
