Which of the following regions/cells in the human body is involved in controlling blood sugar level?

Result
Your answer: —  Â·  Correct: B
Explanation

The Islets of Langerhans are the endocrine regions of the pancreas responsible for regulating blood sugar levels [t8][t9]. These clusters contain specialized cells, primarily beta cells and alpha cells [t8]. Beta cells act as glucose sensors and secrete insulin when blood sugar levels rise, facilitating glucose uptake by body cells [c1][t5]. Conversely, alpha cells secrete glucagon in response to low blood glucose to increase circulating sugar levels [t8]. While the hypothalamus and pituitary gland regulate general metabolism and other endocrine functions, the direct detection and immediate hormonal response to blood glucose fluctuations occur within these pancreatic islets [c1][t2]. The spleen is primarily involved in immune function and blood filtration rather than glucose regulation. Thus, the Islets of Langerhans are the primary site for maintaining glucose homeostasis [t5][t10].
