Sample item

Which organ is chiefly responsible for maintaining blood glucose during an overnight fast?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

C. Liver

The liver maintains blood glucose during fasting through glycogenolysis and gluconeogenesis, supplying glucose to dependent tissues.

Option by option

  • A. Thyroid gland

    Thyroid hormones influence metabolism but do not release glucose directly.

  • B. Spleen

    The spleen filters blood rather than regulating glucose.

  • C. Liver (correct)

    Correct: the liver buffers fasting glucose supply.

  • D. Skin

    Skin is not the primary fasting glucose source.
