Question

Insulin is secreted by:

• A. Thyroid gland
• B. Pancreas
• C. Pituitary gland
• D. Testis

Hint:

Insulin is crucial for regulating blood glucose levels and is secreted by the pancreas.

Answer 1

The Correct Option is B

Insulin is a hormone that is secreted by the pancreas, specifically by the beta cells of the islets of Langerhans. It plays a key role in regulating blood sugar (glucose) levels by facilitating the uptake of glucose into cells for energy production or storage.
- Option (A) Thyroid gland secretes thyroid hormones (T3 and T4), not insulin.
- Option (C) Pituitary gland secretes various hormones like growth hormone, but not insulin.
- Option (D) Testis primarily secrete testosterone, not insulin.
Thus, the correct answer is (B) Pancreas.
