Textbook Question

Match the letter of the digestive organ shown in the figure with its function.
___ produces both endocrine and exocrine secretions

Verified step by step guidance

Step 1: Begin by identifying the organ in the figure that produces both endocrine and exocrine secretions. In the human digestive system, the pancreas is the organ responsible for these functions.

Step 2: Understand the endocrine function of the pancreas. It involves the secretion of hormones such as insulin and glucagon directly into the bloodstream to regulate blood sugar levels.

Step 3: Understand the exocrine function of the pancreas. It involves the production and secretion of digestive enzymes (e.g., amylase, lipase, proteases) into the small intestine via the pancreatic duct to aid in digestion.

Step 4: Match the letter in the figure corresponding to the pancreas with its function of producing both endocrine and exocrine secretions.

Step 5: Review the figure carefully to ensure the correct identification of the pancreas and its associated letter, and confirm the dual role of endocrine and exocrine secretions.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Endocrine and Exocrine Functions

Endocrine glands release hormones directly into the bloodstream, regulating various bodily functions such as metabolism and growth. In contrast, exocrine glands secrete substances through ducts to specific sites, such as digestive enzymes into the gastrointestinal tract. Understanding the distinction between these two types of secretions is crucial for identifying the organ responsible for both functions.

Pancreas

The pancreas is a vital organ that serves both endocrine and exocrine roles. It produces insulin and glucagon, which are hormones that regulate blood sugar levels, representing its endocrine function. Simultaneously, it secretes digestive enzymes like amylase and lipase into the small intestine, illustrating its exocrine function. Recognizing the pancreas's dual role is essential for answering questions about digestive organ functions.

Digestive System Overview

The digestive system comprises various organs that work together to break down food, absorb nutrients, and eliminate waste. Each organ has specific functions, such as the stomach's role in digestion and the intestines' role in absorption. Understanding the overall structure and function of the digestive system helps in accurately matching organs with their respective roles, particularly in the context of the pancreas.
