  1. The small intestines and the first 2/3 of the large intestine are supplied with blood by what artery?

  2. The Superior Mesenteric Artery

  3. The Superior Mesenteric artery branches into what arteries?

  4. The mesenteric arteries.

  5. Name the first branch off the aorta below the diaphragm

  6. The celiac artery

  7. The celiac artery branches into what three arteries?

  8. The gastric, splenic, and hepatic arteries.

  9. What organs do these arteries supply blood to?

  10. The gastric supplies blood to the stomach, the splenic supplies blood to the spleen, and the hepatic supplies blood to the liver.

  11. Are there celiac, inferior, and superior mesenteric veins that empty directly into the vena cava?

  12. No. The celiac, inferior, and superior mesenteric veins empty into the Hepatic Portal System.

  13. What is this thin shiny watery mesh-like membrane?

  14. Mesentery

  15. Name this red blood vessel.

  16. Mesenteric artery

  17. Name this yellow stained blood vessel.

  18. Mesenteric vein.

  19. What does the Hepatic Portal System empty into?

  20. The liver

  21. The large yellow vein that the mesenteric veins empty into is called?

  22. The Hepatic Portal Vein

  23. What are the special macrophages in the liver that phagocytize debris and bacteria and also cleanse the blood?

  24. Kupffer cells which prowl the walls of the liver sinusoids.

  25. What artery takes blood the the last 1/3 of the Large intestine?

  26. The inferior mesenteric artery.

  27. Products of digestion that are filtered through the Hepatic Portal System are said to be?

  28. Blood-borne

  29. What products of digestion are Blood-borne?

  30. Amino acids, monosaccharides, disaccharides, etc.

  31. In the small intestine, name the finger-like projections that increase the surface area for absorption of nutrients.

  32. Villi (singular villus)

  33. Each villus contains a capillary bed and what other structure?

  34. A lacteal, a dead-end beginning of a lymphatic vessel.

  35. What is the function of the lacteal within the villus?

  36. Lacteals absorb excess interstitial fluid and are responsible for picking up and transporting the products of fat digestion.

  37. What are the products of fat digestion?

  38. Monoglycerides, diglycerides, glycerol, cholesterol, etc.

  39. What structure do the products of fat digestion originally become?

  40. Chylomicrons--packages of fatty things surrounded by a transport protein

  41. Chylomicrons are made by the brush border cells and exported to what dead-end vessels?

  42. Lacteals. What larger and larger vessels do lacteals empty into?

  43. Lymphatic vessels

  44. The lymphatic fluid in these vessels passes through what structures?

  45. Lymph nodes

  46. What is the name of the large sinus that the lymphatic vessels eventually empty into?

  47. The cisterna chylii

  48. The ciserna chylii is the beginning of what main duct in the lymphatic system?

  49. The thoracic duct

  50. The thoracic duct empties into what vessel?
