Which of the following is NOT true about the pancreas?
A
The pancreas has both endocrine and exocrine functions.
B
The pancreas is a primary lymphoid organ involved in the maturation of T cells.
C
The pancreas produces insulin to regulate blood glucose levels.
D
The pancreas secretes digestive enzymes into the small intestine.
Verified step by step guidance1
Step 1: Begin by understanding the role of the pancreas in the human body. The pancreas is a dual-function organ with both endocrine and exocrine roles. Its endocrine function involves producing hormones like insulin and glucagon to regulate blood glucose levels, while its exocrine function involves secreting digestive enzymes into the small intestine to aid in digestion.
Step 2: Review the statement 'The pancreas has both endocrine and exocrine functions.' This is true based on the pancreas's dual roles described above.
Step 3: Examine the statement 'The pancreas produces insulin to regulate blood glucose levels.' This is also true, as insulin is a hormone produced by the beta cells in the pancreas to lower blood glucose levels.
Step 4: Analyze the statement 'The pancreas secretes digestive enzymes into the small intestine.' This is true as well, since the pancreas produces enzymes like amylase, lipase, and proteases that are released into the small intestine to break down carbohydrates, fats, and proteins.
Step 5: Evaluate the statement 'The pancreas is a primary lymphoid organ involved in the maturation of T cells.' This is NOT true. The primary lymphoid organs responsible for T cell maturation are the thymus and bone marrow, not the pancreas. Therefore, this statement is incorrect.
