Question

The blood sugar level is regulated by
a. Pancreas
b. Thyroid
c. Anterior pituitary
d. Posterior pituitary
e. Hypothalamus

Answer 1

Hint: Insulin lowers the blood glucose level by restoring the absorption of glucose by cells while glucagon stimulates the breakdown of glycogen into glucose to increase the sugar level in blood.

Complete answer:
> The Pancreas is an organ in the body that manufactures many digestive juices which are supplied to the small intestine that is in the duodenum. These digestive juices are filled with enzymes like lipase, protease, and amylase. In Pancreas there is a group of cells that acts as glands and they secrete hormones like insulin, glucagon, Amylin, etc. Among these insulins helps to control the blood glucose level in the body and glucagon controls the glycogen by breaking it down.

> The Thyroid gland helps in the growth and development and metabolism of the human body. The hormones released are called thyroid hormones and are secreted into the bloodstream. In some specific situations, the hormone secretion becomes more like during growing age.

> The anterior pituitary gland secretes a hormone that stimulates the thyroid glands and the adrenaline glands. Adrenaline glands secrete a steroid hormone called cortisol.

> ADH or the antidiuretic hormone is secreted by the posterior pituitary gland. This helps in saving water by reabsorbing it in the kidney.

> The hypothalamus controls the pituitary glands and their secretions. The hypothalamus has two receptors, which can sense water depletion. It is a small area in the brain and connects many nerve fibers.

Hence, the correct answer is option (A).

Note: Islets of Langerhans are the main areas in the pancreas to produce insulin. Insulin stimulates the cells to take up glucose. Glucagon helps in breaking down glycogen. Without insulin, the glucose level rises and leads to the development of diabetes.
