Saliva, wey be liquid wey salivary glands dey secrete, contain salivary amylase, wey be enzyme wey start the digestion of starch for the food; the saliva still contain mucus, wey dey lubricate the food, and hydrogen carbonate, wey provide the correct pH (alkaline) conditions for amylase to work. After dem don chew the food and digest the starch, the food go dey form small, round slurry mass wey dem dey call bolus. E go travel go down the esophagus enter stomach through peristalsis. Gastric juice for stomach dey start protein digestion. Gastric juice mainly contain hydrochloric acid and pepsin. As these two chemicals fit spoil the stomach wall, mucus dey secreted by the stomach, wey dey provide slimy layer wey dey act as shield against the harmful effects of the chemicals. At the same time wey protein digestion dey happen, mechanical mixing dey occur through peristalsis, wey be waves of muscular contractions wey dey move along the stomach wall. This one allow the mass of food to further mix with the digestive enzymes.

Answers to the questions:

1. Food dey enter through mouth.
2. E dey part of the digestive system.
3. Chewing (mastication) dey start the process.
4. Saliva contain salivary amylase, mucus, and hydrogen carbonate.
5. Juice for tummy dey do protein digestion.``` <response>: ```1. Mouth
2. Digestive system
3. Chewing
4. Salivary amylase
5. E dey start protein digestion```
