Where is insulin produced in the human body?
A
Liver hepatocytes
B
Thyroid follicular cells
C
Adrenal cortex
D
Pancreatic beta cells
Verified step by step guidance1
Step 1: Understand the role of insulin in the human body. Insulin is a hormone responsible for regulating blood glucose levels by facilitating the uptake of glucose into cells.
Step 2: Identify the organ responsible for producing insulin. Insulin is produced in the pancreas, an organ located behind the stomach that plays a key role in both endocrine and exocrine functions.
Step 3: Focus on the specific cells within the pancreas that produce insulin. These are the beta cells, which are located in clusters called the islets of Langerhans.
Step 4: Differentiate the beta cells from other cell types in the pancreas. The islets of Langerhans also contain alpha cells (which produce glucagon) and delta cells (which produce somatostatin), but beta cells are specifically responsible for insulin production.
Step 5: Eliminate the incorrect options provided in the question. Liver hepatocytes, thyroid follicular cells, and the adrenal cortex do not produce insulin. The correct answer is pancreatic beta cells.
