X

X

-

Only used to pass the chewed food to stomach

Stomach

X

D

X

Protease starts digestion on proteins

Here salivary Amylase stops working due to low pH

Small intestine

D, A

D, A

D, A

Absorption of minerals.

Here various enzymes are present like protease, amylase and lipase which digest carbohydrate, fat and proteins.

Pancreas

X

X

X

-

It is involved in the formation of enzyme protease, amylase and lipase

It provides the enzymes to small intestine to digest the food.

Liver

X

X

-

It forms bile salts which is required in the digestion of fat.

Gall bladder

X

X

X

-

It stores the bile salts formed by liver.

It provides bile salts in small intestine for the digestion of fats.

Large intestine
