4. Demographic transition is the shift from high birth and death rates to high birth and low death rates and finally to low birth and death rates. Demographic transition reduces the rate of population growth of a country.

Hormones play an important role in regulating blood glucose levels. what is an example of this?

Ber [7]

The human body wants blood glucose (blood sugar) maintained in a very narrow range. Insulin and glucagon are the hormones which make this happen. Both insulin and glucagon are secreted from the pancreas, and thus are referred to as pancreatic endocrine hormones. The picture on the left shows the intimate relationship both insulin and glucagon have to each other. Note that the pancreas serves as the central player in this scheme. It is the production of insulin and glucagon by the pancreas which ultimately determines if a patient has diabetes, hypoglycemia, or some other sugar problem.(i hope this can help you) :)
