Explanation:

1. Salivary glands produce saliva which helps in digestion. The description "these help the digestive process by emptying saliva into the mouth; the saliva moistens food, making it easier to chew and swallow" (l) matches.
2. Pharynx is also called the throat. The description "also called the throat; it passes food from the mouth to the esophagus" (i) matches.
3. Mastication is the process of chewing (fragmenting food in the mouth). The description "fragmenting of food in the mouth" (f) matches.
4. Chyme is the semi - liquid form of food leaving the stomach. The description "semi - liquid form of food which leaves the stomach" (a) matches.
5. Epiglottis is a flap - like structure that prevents food from entering the lungs. The description "valve which keeps food from going into the lungs" (n) matches.
6. Fats are broken down into fatty acids and glycerol. But there is no correct match in the given options (assuming no error in the problem setup, maybe a mis - print. If we consider the closest, but strictly as per given options, no correct match. But if we assume the problem has an error and we consider the description for enzymes (b) is wrong for the given term, and if we re - assign, but as per the problem, we go with the given).
7. Esophagus is a muscular tube from pharynx to stomach. The description "muscular tube that conveys food from the pharynx to the stomach" (g) matches.
8. Gastric juices are produced in the stomach. The description "produced in the stomach, they aid the digestion of food; made up of water, mucus, hydrochloric acid, and the enzyme pepsin" (j) matches.
9. Peristalsis is the muscle contraction movement of food. The description "process by which muscle contractions move food along the digestive tract" (c) matches.
10. Carbohydrates are broken down into simple sugars. The description "they are broken down into simple sugars during the digestive process" (e) matches.
11. Stomach is a J - shaped sac. The description "J - shaped sac which stores food before passing it on to the small intestine" (h) matches.
12. Proteins are broken down into amino acids. The description "they are broken down into amino acids during the digestive process" (d) matches.
13. Enzymes help break down food. The description "chemicals which help break down food during the digestive process" (b) matches.
14. Uvula is a flap - like projection to keep food from nose. The description "flap - like projection which keeps food from going into the nose" (k) matches.
