Explanation : parasympathetic nervous system stimulate GIT and increases secretion of digestive juice and increases rate of digestion while sympathetic outflow is the antagonist to the parasympathetic outflow that's why they inhibit all this process ..

Question No.10

Answer :- apical side of epithelial cell → basolateral side of epithelial cell → interstitial fluid → blood

Question No.11

Answer: None of the alternatives

Explanation : chief cell of stomach secrete pepsinogen and chymosin that break down fat .

Question No.12
Answer :- small intestine

Explanation : Bicarbonate secretion occurs primarily in the duodenum to neutralise chyme released from stomach.... Thanks dear student
