13) In ------ phase the gastric acid secretion inhibited.

14) Parietal cells secrete pepsin enzyme.

15) Pepsin is not essential for protein digestion.

Pepsin is active only in the presence of a low H+ concentration

secretin lowers of acid secreation

1) The inactive forms of proteolytic enzymes are called zymogens.

2) Enterokinase convert trypsin into trypsinogen.

3) ------ function is splits polysaccharides into glucose and maltose.

4) All pancreatic enzymes are secreted as inactive forms.

5) ----- stimulate HCO3- secretion.

6) Which of the following stimulate CCK secretion?

7) Bile pigments are formed from the globin portion of hemoglobin.

1) Water movement into the lumen occurs when the chyme entering the small intestine from the stomach is -----

2) The rhythmic contraction and relaxation of the intestine known as segmentation.

3) The main function of intestinal movement is movement of food content.

4) The frequency of segmentation in ----- is about 12 contractions/ minute

5) In small intestine ----- increase the force of contraction while ----- decrease it.

6) The inputs like hormones and enteric nervous system change the force of muscle contraction only.

7) Migrating myoelectrical complex begins in the lower portion of the stomach.

8) After most of meal has been absorbed the migrating myoelectrical complex ends.

9) ------ stimulate migrating myoelectrical complex.
