Choose the correct option. A. Acinar cells are present in .......... a. liver b. pancreas c. gastric glands d. intestinal glands B. Which type of teeth are maximum in number in the human buccal cavity? a. Incisors b. Canines c. Premolars d. Molars C. Explain heterocrine nature of pancreas with the help of histological structure. 2. Answer the following questions. A. For the school athletic meet, Shriya was advised to consume either Glucon-D or fruit juice but no sugarcane juice. Why must it be so? B. Alcoholic people may suffer from liver disorder. Do you agree? Explain your answer. C. Digestive action of pepsin comes to a stop when food reaches the small intestine. Justify. D. Small intestine is very long and coiled. Even if we jump and run, why does it not get twisted? What can happen if it gets twisted? 3. Write down the explanation. A. Digestive enzymes are secreted at appropriate time in our body. How does it happen? B. Explain the structure of tooth. Explain why human dentition is considered as thecodont, diphyodont and heterodont.
Understand the Problem
The image presents a set of biology exercise questions focusing on human anatomy and digestion. The questions require knowledge of various aspects such as gland functions, types of teeth, digestive processes, and specific structures and functions in the human body.
Answer
A: Pancreas. B: Molars. C: Heterocrine - Both endocrine and exocrine functions. Pepsin stops due to pH change.
The final answer is: A. Acinar cells are present in the pancreas. B. Molars are the maximum in number in the human buccal cavity. C. The heterocrine nature of the pancreas refers to its dual functions: endocrine (hormone secretion) and exocrine (digestive enzyme production). For question D, digestive action of pepsin stops in the small intestine due to a change in pH.

For question D, digestive action of pepsin stops in the small intestine due to a change in pH.
More Information
Acinar cells in the pancreas secrete digestive enzymes. Molars help in grinding food. The heterocrine nature of the pancreas involves both hormone release into the bloodstream and enzyme release into the digestive tract. Pepsin is inactivated by the alkaline environment of the small intestine.
Tips
Misunderstanding the heterocrine function of the pancreas means missing its dual role in the digestive and endocrine systems.
