  5. Greater omentum
    Greater curvature of stomach to transverse colon
  6. Lesser omentum

    • modifies hormones
    • phagocytosis of foreign materials from intestines
  12. Cirrhosis of liver

    • fibrotic tissues and nodules in liver that disrupt internal architecture - disrupt blood flow --> portal HTN --> varices of portal vein, ascites (fluid in abdomen), caput medusae, enlarged spleen
    • symptoms include neurological symptoms due to inability to filter toxins
    • due to ETOH and viral hepatitis
