Ch. 36 part.3-gastric motility

  • chyme production; pushed through pyloric canal into small intestine

    What are the two functions of gastric smooth muscle contraction?

  • a

    The _________ shows low frequency contractions that create a basal tone.

    a)upper stomach

    b) lower stomach

  • b

    The ________ shows high frequency peristaltic contractions.

    a) upper stomach

    b) lower stomach

  • gastric distention

    _________ strongly stimulates peristaltic waves of contraction, accelerating liquefaction, resulting in gastric emptying.

  • neural; hormonal

    Gastric motility is controlled by a very complex set of : ______ & _______ signals.

  • relax the proximal stomach; enhance contractions in distal stomach

    How do Gastrin & Choleycystokinin affect gastric motility?

  • mixing contents w enzyems, increasing surface area, propulsion into large intestine

    What are 3 functions that motility of small intestines serves?

  • segmentation

    -contractions that chop, mix, and roll the chyme

  • peristalsis

    -a ring of muscle contraction that slowly propels chyme toward the large intestine

  • c

    Segmentation usually occurs in the _______.

    a) stomach

    b) large intestine

    c) small intestine

    d) liver

  • segmentation, antiperistaltic, mass movements

    What are the 3 methods of large intestine motility?

  • haustration

    -a mixing, modified segmentation movement

  • haustra

    -bulge -sac like appearance of large intestine

  • anti-peristalsis

    -propagate bolus toward the ileum; allows additional opportunity for absorption of water and electrolytes.

  • cranially

    Anti-peristalsis moves large intestinal contents ________.

  • b

    Mass movements are ONLY found in the _________.

    a) stomach

    b) large intestine

    c) small intestine

    d) liver

  • mass movement

    -a very intense and prolonged peristaltic contraction which strips an area clear of contents.

  • dormant; extremely active

    The colon is _______ between meals and __________ after meals

  • duodenocolic reflexes

    -reflexes stimulated exclusively by the presence of fat in the proximal small intestine

  • gastrocolic reflex

    -serves as a stimulus for defecation

  • d

    Which organ is responsible for producing bile and filtering toxins and waste including drugs, alcohol, and poisons?

    a) stomach

    b) large intestine

    c) small intestine

    d) liver

  • gall bladder

    -stores bile from liver

    -fatty diets can cause gallstones to form here

  • fats

    Bile helps digest ________.

  • c

    Gall bladder releases bile into the _______

    a) stomach

    b) large intestine

    c) small intestine

    d) liver
