blood glucose levels diabetes

negative feedback system for blood glucose levels

receptor detect levels not at optimum level

at coordination centre brain decides what action to take

effector carries out action- the pancreas

if blood glucose levels too high the pancreas will

release insulin

the insulin triggers two things

body cells to uptake glucose

liver to store excess glucose

the liver stores excess glucose molecules as

glycogen

when levels drop too low

the pancreas releases glucagon

the glucagon triggers the liver to

convert glycogen back to glucose molecules and release into bloodstream

some people can`t regulate their own glucose levels

this is type 1 diabetes or type 2

type 1 is where

the body produces little to no insulin

type 1 can be managed with

insulin injections throughout the day

the amount of injections depends on

how much exercise is done - more activity = more insulin sensitive

balanced diet

type 2 is when

the body is resistant and no longer responds to the insulin it creates

a risk factor for type 2 is

obesity

type 2 can be managed through

a balanced diet and exercise
