Question

Which hormones do stimulate the production of pancreatic juice and bicarbonate?
A. Cholecystokinin and secretin
B. Insulin and glucagon
C. Angiotensin and epinephrine
D. Gastrin and insulin

Answer 1

Hint: Cholecystokinin acts on both pancreas as well as gall bladder along with stimulates the secretion of pancreatic and bile juice respectively. Secretin acts on the exocrine pancreas and it stimulates the secretion of bicarbonate ions in the body.

Complete answer:
Option A- The small intestine secretes 4 types of hormones; cholecystokinin, secretin, gastric inhibitory peptide (GIP) as well as Motilin. While Cholecystokinin and secretin are emitted by all the three parts of the small intestine that are respectively duodenum, jejunum, and ileum, GIP, as well as motilin, is secreted by only the duodenum and jejunum. Cholecystokinin is generated by the 'I' cells, 'S' cells elicit secretin, GIP is constructed by the 'K' cells and the 'M' cells secrete motion. These hormones are emitted as a result of various stimuli such as protein, fat, carbohydrate as well as acid in the intestine.
Option B - Glucagon works to equalize the actions of insulin. About four to six hours after you intake the glucose levels in your blood drop, triggering your pancreas to produce glucagon. This hormone signals in your liver and muscle cells to shift the stored glycogen back into glucose.
Option C - Angiotensin (Ang)II and epinephrine (Epi) provoke hemodynamically as well as metabolic responses in a normal liver. These reactions are modified in various ways in two models of hypertension.
Option D- The outcomes demonstrate that gastrin can stimulate a rapid as well as the short-lived release of insulin. In physiologic concentrations, gastrin potentiates the glucose-stimulated insulin secretion along with it in the absence of its effect on basal insulin secretion

So, the valid answer to the above question is Option – A - 'Cholecystokinin and secretin'.

Note:
Pancreatic secretions are also the main mechanism for neutralizing gastric acid in the small intestine of a body. When acid reaches the small gut, it stimulates secretin to be discharged, and the effect of this hormone is to stimulate the secretion of lots of bicarbonate.
