digestion and absorption

1. 1glucose absorption from the intestinal lumen is linked to sodium transport

   1. ATrue
   2. BFalse
2. 2PROCESS OF SECONDARY ACTIVE TRANSPORT:
   involves the generation of a [blank_start]sodium[blank_end] concentration gradient within the cell via the action of the ATP dependant [blank_start]Na+/K+ ATPase pump[blank_end]. sodium will then enter the cell on the [blank_start]luminal[blank_end] side via the [blank_start]Na+/glucose co-transporter[blank_end] along with [blank_start]glucose[blank_end]. It is active because ATP is required to set up the gradient, but it does not directly involve energy

   1. ATrue
   2. BFalse
5. 5trypsin is a pancreatic zymogen

   1. ATrue
   2. BFalse
6. 6all digestive enzymes are hydrolases

   1. ATrue
   2. BFalse
7. 7enzymes such as lactase and sucrase are secreted into the intestinal lumen to act upon their substrates

   1. ATrue
   2. BFalse
8. 8psychogenic diarrhoea is caused by excessive stimulation of the sympathetic nervous system

   1. ATrue
   2. BFalse
9. 9pancreatitis can be caused by over activation of the zymogens trypsin and chymotrypsin

   1. ATrue
   2. BFalse

    7. Gethnic background
    8. Hgall stones

11. 11what layer of the stomach lining would you find the secretory glands

    1. Amucosa
    2. Bsubmucosa
    3. Cadventitia
    4. Dserosa
12. 12what is the semifluid called that is produced by gastric digestion of food and peristalsis

    1. Achyme
    2. Bbile
    3. Cbolus
    4. Ddigestive fluids
13. 13where are proteins first digested

    1. Astomach
    2. Bsmall intestine
    3. Clarge intestine
    4. Dcolon
14. 14what is the name of the enzyme that breaks down kininogen and dilation of the blood vessels supplying the salivary glands

    1. Atrypsin
    2. Bkallikrein
    3. Calpha amylase
    4. Dlipase
15. 15which of the salivary glands secrete the majority of the digestive enzymes

    1. Aparotid
    2. Bsubmandibular
    3. Csublingual
16. 16what are the epithelial cells that line the lumen of the small intestine termed

    1. Atransitional epithelium
    2. Bparietal cells
    3. Centerocytes
    4. Dgastric chief cells
17. 17stomach juices are acidic due to the fact that they need to destroy bacteria and provide an optimum pH for the activity of pepsin

    1. ATrue
    2. BFalse
18. 18what mechanism is water absorbed from the intestine

    1. Apassive diffusion
    2. Bfacilitated diffusion
    3. Cosmosis
    4. Dactive transport
19. 19a 22 year old man presented with a history of weight loss, diarrhea, abdominal bloating and anaemia. He described his stools as pale and bulky. lab results included haemaglobin of 90g/L (normal 130-180 g/L). a biopsy was taken of his small bowel

    1. Acoeliac disease
    2. Bbowel cancer
    3. Cpancreatitis
    4. Dcrohns disease
20. 20COELIAC DISEASE:
    its an [blank_start]autoimmune[blank_end] disease caused by sensitivity to gluten, which causes inflammation of the small bowel [blank_start]mucosa[blank_end]. the resulting damage to the [blank_start]mucosa[blank_end] means that the absorptive surface of the [blank_start]small intestine[blank_end] is reduced and the subsequent [blank_start]malabsorption[blank_end] is severe. Pale, bulky stools are a hallmark of steatorrhea, or malabsorption of [blank_start]lipids[blank_end], which are passed in the feces rather than absorbed in the intestine.

    1. Aautoimmune
    2. Bviral
    3. Cbacterial
    4. Dmucosa
    5. Esubmucosa
