Question

the pancreas produces ______ secretions that include digestive enzymes and hormones, respectively.
secretory and absorptive
serous and sebaceous
exocrine and endocrine
merocrine and holocrine
mucous and acid

Explanation:

To solve this, we analyze each option:

• "secretory and absorptive": Absorptive is not a main secretion type of the pancreas. Eliminate.
• "serous and sebaceous": Sebaceous is related to skin, not pancreas. Eliminate.
• "exocrine and endocrine": The pancreas has exocrine (digestive enzymes via ducts) and endocrine (hormones like insulin, glucagon, into blood) functions. This matches.
• "merocrine and holocrine": These are glandular secretion methods, not the main secretion categories of pancreas. Eliminate.
• "mucous and acid": Mucous and acid are more related to stomach, not pancreas' main secretions. Eliminate.

Answer:

C. exocrine and endocrine
