D. FUNGUS OF STOMACH |
E. BODY STOMACH |
F. PANCREAS |
G. DESCENDING COLON |
H. SMALL INTESTINE |
I. RECTUM |

L. RIGHT LOBE OF LIVER |
1) From the given table
digestive organs are
ESOPHAGUS
STOMACH
PANCREAS
DESCENDING COLON
SMALL INTESTINE
RECTUM
GALL BLADDER
LIVER
2) ESOPHAGUS - no digestive secretions, only mechanical digestion
STOMACH- stomach produce Hydrochloric acid for digestion
digestive enxymes like pepson(convert protein in to aminoacid), gastric lipase( fat into fatty acid and glycerol), Intrinsic factor for the absorption of vitamin b12, mucin, Gastrin
PANCREAS
trypsinogen
chymotrypsinogen
carboxypeptidase
pancreatic lipase
pancreatic amylase
pancreatic nuclease
SMALL INTESTINE
secretin, motilin,cholecystokinin,Gastric inhibitory peptide,maltase,lactasesucrase
NO DOGESTION IN DESCENDING COLON,RECTUM
GALL BLADDER : store and concentrate Bile
LIVER : production of Bile , which help in the digestion of fat
3)Food bolus is formed in the mouth as a result of the mechanical chewing of the food by the teeth and the saliva help in the cohesiveness between the food particle.
Chyme is produced in the stomach
it is by the mixing of the food particles with the digestive enxymes in the stomach make it a white semi fluid material
4)Major site of food absorption is the small intestine
small intestine contain finger like projection called villi, on the surface of the villi there is small projection called microvilli. Both of this increase the surface area of the absorption.
5)waste product are formed in the large intestine
Rectum of the large intestine stores the waste product until is has been eliminated from the body
6)waste product are eliminated through the Anus.
