  1. 1Choose the incorrect statement about the eosophagus
    1. AIs pH 6 - 7
    2. BSwallows via peristalsis
    3. CEpithelia is protective and secretes mucous
    4. DCan be affected by dysphagia, perforation
  2. 2The ileum is the main site for drug absorption.
    1. ATrue
    2. BFalse
  3. 3Which of these is not a main function of the stomach?
    1. AControl of food delivery
    2. BStorage of food
    3. CBeginning digestion
    4. DAbsorption
  4. 4pH changes along the GIT.
    Fasted state average pH in the stomach = [blank_start]1.3[blank_end], duodenum = [blank_start]6.5[blank_end], jejunum = [blank_start]6.6[blank_end], ileum = [blank_start]7.4[blank_end].
    Fed state average pH in the stomach = [blank_start]4.9[blank_end], duodenum = [blank_start]5.4[blank_end], jejunum = [blank_start]5.2-6[blank_end], ileum = [blank_start]7.5[blank_end].
    1. A1.3
    2. B6.5
    3. C6.6
    4. D7.4
    5. E4.9
    6. F5.4
    7. G5.2-6
    8. H7.5
  5. 5Which of these is not a cell that has secretions directly affecting small intestine pH?
    1. AParietal cells
    2. BBrunner's glands
    3. CIntestinal goblet cells
  6. 6Gastric emptying is important in determining/controlling the [blank_start]onset of drug action[blank_end] because it controls how [blank_start]quickly[blank_end] a drug gets to the main site of absorption([blank_start]intestine[blank_end]). It also controls the time a drug spends in a [blank_start]low pH environment[blank_end] which has implications for stability.
    1. Aonset of drug action
    2. Bquickly
    3. Cintestine
    4. Dlow pH environment
  7. 7In general, a fasted state promotes shorter gastric residence time.
    1. ATrue
    2. BFalse
  8. 8The fasted pattern of motility in the stomach is also known as the [blank_start]migrating myoelectric complex[blank_end], MMC. The fasted stomach is [blank_start]less discriminatory[blank_end] for dosage forms. It has a roughly [blank_start]2h[blank_end] cycle.
    1. Amigrating myoelectric complex
    2. Bless discriminatory
    3. C2h
    4. D4h
  9. 9Because of the [blank_start]sieving[blank_end] effect in the stomach, during the [blank_start]fed[blank_end] state larger particles are retained [blank_start]longer[blank_end] due to [blank_start]retropulsion[blank_end] whereas small particles in [blank_start]trubulent fluids[blank_end] are emptied more [blank_start]rapidly[blank_end].
    1. Asieving
    2. Bfed
    3. Cfasted
    4. Dlonger
    5. Eturbulent fluids
    6. Frapidly
    7. Gretropulsion
  10. 10Lymphatics in the small intestine are important for absorption of fats, protein drugs and [blank_start]lipid soluble[blank_end] drugs — they transport proteins [blank_start]intact[blank_end] across the GIT. There are lymphatic capillaries and [blank_start]lymphoid tissue[blank_end], such as the fat deposits on the [blank_start]ileum[blank_end] known as Peyer's patches. They contain [blank_start]M cells[blank_end] and are important for the [blank_start]immune[blank_end] system.
    1. Alipid soluble
    2. Bintact
    3. Clymphoid tissue
    4. Dileum
    5. EM cells
    6. Fimmune
