Regulation of blood glucose

what can too much/too little blood glucose levels lead to?

coma

death

what regulates blood glucose levels?

pancreas

process that regulates blood glucose levels

homeostatic process

how does the pancreas regulate blood glucose concentration?

1. detects concentration

2. releases hormones that alter the amount of glucose in the blood

process of regulating a high blood sugar

pancreas increases secretion of insulin and decreases secretion of glucagon

insulin is released by beta cells in pancreas

insulin causes muscle and liver cells to remove glucose from blood and store it as glycogen

tissue cells store glycogen

this lowers blood sugar

process of regulating a low blood sugar

pancreas increases secretion of glucagon and decreases secretion of insulin

glucagon is released by alpha cells in pancreas

glucagon causes liver cells to convert glycogen to glucose and release it into the blood

this raises blood sugar

what happens to insulin and glucagon secretion if the organism has a high blood sugar?

insulin = increases

glucagon = decreases

what happens to insulin and glucagon secretion if the organism has a low blood sugar?

insulin = decreases

glucagon = increases

what types of cells release insulin?

beta

what type of cells secrete glucagon?

alpha
