Explanation:

• The tongue helps in swallowing by moving the bolus from the mouth into the pharynx. The tongue assists in moving the food around in the mouth and coating the food with saliva. It also helps in swallowing and speech.
• Digestion of starch starts from the mouth due to saliva.Use of many digestive fluids and enzymes like saliva, mucus, bile and hydrochloric acid, among others, is involved in this process.
• The digestion process starts from buccal cavity.
• The gall bladder plays a major role in food digestion. The liver contains bile and it is deposited temporarily in the gall bladder. Bile includes bile acids that are useful in the small intestine for digestion and absorption of fats.
• Grass has cellulose. It is the carbohydrate which can only be digested by ruminants because they have rumen. When they eat grass, it is sent to the rumen where enzymes acts on it and softens it. Softened cellulose is called cud. It is sent back to the mouth where ruminants chew it for sometime.
