    • Frequence of slow waves
      1. 3 > stomach
      2. 12 > duodenum
    • Long chain fatty acids release CCK (I cells) [By acitvating afferent vagal sensory fibres] or Acids secretin (S cells) or irritants serotonin (EC cells) > delay gastric gastric emptying
    • Delayed gastric emptying results from
      1. ENS
      2. Vagovagal reflex: Decreases fundic tone (NO and VIP ) and antral peristalsis while Increasing Pyloric constrictions and duodenul peristalsise
