The correct Answer is:
To determine how many statements are correct, let's analyze each statement one by one: ### Step 1: Analyze Statement A **Statement A:** "All foods begin their enzymatic digestion in the mouth." - **Analysis:** This statement is incorrect. While carbohydrates begin their enzymatic digestion in the mouth due to the action of salivary amylase, proteins and fats do not start their digestion until they reach the stomach. Therefore, this statement is false. ### Step 2: Analyze Statement B **Statement B:** "After leaving the oral cavity, the bolus enters the larynx." - **Analysis:** This statement is also incorrect. After the oral cavity, the bolus (a mass of chewed food) enters the esophagus, not the larynx. The larynx is involved in the respiratory system and is not the correct passage for food. Therefore, this statement is false. ### Step 3: Analyze Statement C **Statement C:** "The epiglottis prevents food from entering the trachea." - **Analysis:** This statement is correct. The epiglottis is a flap-like structure that covers the trachea during swallowing, preventing food from entering the windpipe (trachea) and directing it into the esophagus instead. Therefore, this statement is true. ### Step 4: Analyze Statement D **Statement D:** "Enzyme production continues in the esophagus." - **Analysis:** This statement is incorrect. The esophagus does not produce digestive enzymes; it is primarily a conduit for food to travel from the mouth to the stomach. Therefore, this statement is false. ### Step 5: Analyze Statement E **Statement E:** "The trachea leads to the esophagus and then to the stomach." - **Analysis:** This statement is incorrect. The trachea and esophagus are separate structures. The trachea leads to the lungs, while the esophagus leads to the stomach. Therefore, this statement is false. ### Conclusion After analyzing all the statements: - Statement A: Incorrect - Statement B: Incorrect - Statement C: Correct - Statement D: Incorrect - Statement E: Incorrect Only **one statement (Statement C)** is correct. ### Final Answer **Only 1 statement is correct.** ---

When a person puts food in his mouth, then teeth cut it into small pieces, shew and grind it. The glands A in the mouth secrete a substance B which is mixed with the food by tongue. The substance B contains an enzyme C which starts the digestion of food in the mouth. The slightly digested food from the mouth goes down a tube D. The special type of movements E in the walls of tube D push the food into stomach for further digestion. The stomach wall secretes gastric juice containing three substance F, G and H. One of the functions of F is to kill bacteria which may enters the stomach with food. The substance G protects the inside layer fo stomach from the damaging effect of substance F whereas substance H is an enzyme for digestion. The partially digested food then enters into small intestine for further digestion. (a) What is (i) gland A (ii) substance B, and (iii) enzyme C ? (b) Name the tube D. (c) What is the movement E known as ? (d) What are (i) F (ii) G, and (iii) D ?
