Control of Blood Glucose Concentration Flashcards
what is one of the purposes of glucose
releases energy by respiration
what can cause the concentration of glucose to increase
a rich high carbohydrate meal
what hormone does the pancreas release and what does it do
insulin
it travles through the bloodstream to the whole body and triggers body cells to take glucose form the blood
it also triggers the liver and muscle cells to store excess glucose which is converted into glycogen
what disease can people have when there blood glucose control doesn’t work effectively
diabetes
Name the 2 types of diabetes
type 1 - the pancreas doesn’t produce enough insulin
type 2 - the body cells stop responding to insulin sent from the pancreas
what do type 1 diabetes patient have to do to monitor and do if the blood glucose rises
monitor there blood glucose concentration
and have to inject themselves with insulin if blood glucose rises too much
name 2 way that a person with type 2 diabetes is often treated and the aim of it
they have a controlled level of carbohydrates to prevent the persons blood glucose concentration from rising too high
advised to exercise
what is a risk factor of type 2 diabetes
obesity
what does glucagon trigger
livers cells to convert glycogen stores back to glucose and that glucose is released into the blood
on a graph a persons blood glucose concentration falls and rises slights across the whole day explain why(they do not have diabetes)
the blood glucose concentration is controlled by a balance between insulin and glucagon
if the bgc rises it produces insulin if it drops it releases glycogen
what happens when But what happens if the blood glucose concentration falls in between meals (say for both high and low)
if the blood glucose contraction is too low pancreas releases glucagon into bloodstream
