The pancreas is the organ that secretes insulin to help regulate blood sugar. Insulin is a hormone that helps control the amount of glucose in the bloodstream. When blood sugar levels rise, the pancreas releases insulin, which allows cells to take in glucose and use it for energy or store it for later use. This helps maintain stable blood sugar levels and prevents them from getting too high. Therefore, the pancreas plays a crucial role in regulating blood sugar and preventing conditions like diabetes.

Helps control the function of many other glands
Produces all the hormones in the body
Controls all nerve function in the body
Controls all sex hormones in the body

Correct Answer

These hormones, in turn, regulate the activity of other endocrine glands throughout the body, such as the thyroid, adrenal glands, and reproductive glands. Therefore, the hypothalamus is essential for coordinating and controlling the hormonal balance and overall functioning of multiple glands in the body.
