Which part of the human body produces insulin to regulate blood sugar?

Reviewed by Jordan Morley, Editorial Lead at 247SimpleTests. Written by the 247SimpleTests Editorial Team from the official source material cited on every question.

Correct answer

The pancreas

  1. A The stomach
  2. B The pancreas
  3. C The liver
  4. D The kidneys

Why this is the answer

The pancreas produces insulin, a hormone that regulates the level of glucose (sugar) in the blood by helping cells absorb it. When insulin production or function is impaired, the result can be diabetes. The liver stores and releases glucose and performs many other functions but does not make insulin; the kidneys filter blood to make urine; and the stomach digests food. Knowing key glands and the hormones they produce — such as the pancreas and insulin — is standard human-body content on the General Science subtest.
