How is the level of sugar in vertebrate blood kept constant?

Answer 1

The blood sugar level is controlled mainly by two hormones.1.Insulin 2.Glucagon.Both hormones are secreted from Pancreas. When blood glucose level (sugar level) increases, Insulin is secreted from beta cells of islets of Langerhans in Pancreas. it increases the cellular uptake of glucose which in turn reduce the glucose level in the blood. When glucose level decreases in the blood, Alpha cells secrete Glucagon. It decrease the uptake of glucose by cells and increase glucose level.

Over level of glucose also expelled through urine (Diabetes Mellitus)

Mainly insulin & Glucagon are the controllers of blood glucose level.

Answer 2

That is a very good question. You have Beta cells in pancreas. They produce the hormone Insulin, when blood sugar goes up. You have Alfa cells in pancreas, which produce the hormone Glucagon, when sugar level goes down. So the blood sugar level is maintained in very narrow range of 80 to 140 mg/100 ml. How the glucose level is measured in your body needs expert's comment on this subject.

Answer 3

The level of sugar in vertebrate blood is kept constant through the actions of hormones such as insulin and glucagon. Insulin helps lower blood sugar levels by promoting the uptake of glucose into cells, while glucagon raises blood sugar levels by stimulating the liver to release stored glucose. This balance is regulated to ensure a stable blood sugar level.

Answer 4

By negative feedback system of the body and done basically by regulation of glucagon and insulin in the blood.

Answer 5

By less of intake of sugary food into the body
