➡️ Saliva
➡️ Gastric Glands
➡️ Pancreas
➡️ villi
➡️ Large Intestine .

Answer 1

SALIVA

1 make the food soften

2 help in digestion of carbohydrate

GASTRIC GLAND

1 produces several gastric juices

2 secrete HCl (hydrochloric acid

PANCREAS

1 secrete several hormones

2 secrete several digestive enzymes

VILLI

1 absorption of nutrients in the lumen

2 seceretion of several digestive enzymes

LARGE INTESTINE

1 absorb water from the remaining indigestible food matter

Answer 2

hello

here is your answer

➡️ Saliva

(1) Chemical digestion: breaks down starch by the function of “salivary amylase”

(2) Helps chewing and swallowing

➡️ Gastric Glands

(1) GASTRIC GLANDS are present in the walls of the stomach and secrete GASTRIC JUICE

(2) The Gastric juice contains three substances-1)Hydrochloric acid,2)Enzyme Pepsin,3)Mucus

➡️ Pancreas

(1) A healthy pancreas produces the correct chemicals in the proper quantities, at the right times, to digest the foods we eat.

(2) The pancreas contains exocrine glands that produce enzymes important to digestion.

➡️ villi

(1) The villi increase the surface area for absorptionof digested food.  
     
(2) It absorbs all the nutrients from the food and convert it into glucose.

➡️ Large Intestine

(1) After digestion of food particles was completed , it moves to large intestine there

(2) It stores the waste food materials .
