During which phase in the control of the digestive system would bicarbonate and bile be stimulated? view available hint(s) during which phase in the control of the digestive system would bicarbonate and bile be stimulated?
a. intestinal phase
b. gastric phase
c. cephalic phase

Gastric Phase

Explanation:

Background Knowledge:

For food digestion both the nervous system and endocrine system work in collaboration with each other. Purpose of this collaboration is to increase gastric secretion soon after food is eaten and to reduce secretion  when the stomach empties.

Gastric activity:

Gastric activity related to eating can be divided into three stages called the 1) Cephalic phase: Stomach Digestion is being controlled by the brain

2) Gastric phase: Stomach Digestion is being controlled by itself

3) Intestinal phase: Stomach Digestion is being controlled by the small intestine.

Answer of the question:

About 50 to 60 % of the digestive material including Bicarbonates and biles are secreted by Gastric phase

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
