Question

The low blood sugar level is maintained due to the secretion of hormone by the gland

• A. Thyroid
• B. Pancreas
• C. Parathyroid
• D. Adrenal medulla
• E. Anterior pituitary

Answer 1

The correct option is B Pancreas

Thyroxine is thyroid hormone which targets all tissues and stimulates metabolic rate, growth and development. Antagonistic functions of insulin and glucagon hormones of pancreas maintain the homeostasis of blood glucose level. Insulin is secreted by islets of Langerhans of the pancreas and serves to lower the blood glucose level by stimulating the uptake of glucose by cells, specifically muscle cells, liver cells and adipose tissues cells. Glucagon hormone from pancreas stimulates the liver to break down glycogen into glucose and breakdown of fat into glycerol and fatty acids in adipose tissues to serve as the substrate for glucose formation in liver cells. Parathormone of parathyroid gland reduces the blood phosphate level while increases the blood calcium level. Hormones of adrenal gland serve to prepare the body for the long term and short term stress responses.

Therefore, the correct answer is option B.
