Slide 8 - Slide

Regulating Blood Sugar Levels
In this lesson you will be able to:
  • describe the monitoring system, hormones, organs and mechanisms usef to maintain blood glucose at a safe level.
  • explain why it is important to maintain glucose at set levels within the blood.
  • apply understanding of negative feedback and homeostasis

Slide 9 - Slide

The main components
The main components - organs
Liver - responds to hormones and either takes in and stores glucose as glycogen OR breaks down glycogen and releases glucose into blood.
Pancreas - contains receptors that detect changes in blood glucose and in response to this produce one of the two hormones insulin or glucagon.
Muscles - respond to hormones and either take in and store glucose as glycogen OR break down glycogen and release glucose into blood.

Slide 10 - Slide

The main components
The main components - hormones
Insulin 
  • Produced by pancreas when the blood glucose levels go above the accepted level.
  • Travels in blood round the body
  • Stimulates target cells (mainly muscles and liver cells) to remove glucose from blood and convert this to glycogen.
Glucagon - for when the glucose has gone
  • Produced by pancreas when the blood glucose drops below the accepted level
  • Travels in blood round the body
  • Stimulates target cells to break down glycogen store into glucoe and release glucose into teh blood

Slide 26 - Quiz

Slide 27 - Slide

How to change blood glucose
What insulin causes:
All the glucoses removed from the blood are joined together to make glycogen a storage molecule.

What glucagon causes:
Glycogen is broken apart into glucose which is then released into the blood.

Slide 28 - Slide

Slide 29 - Slide

Negative feedback
This is the mechanism used in homeostasis to maintain things at the acceptable level.

The mechanism does the response that negates  the change... reverses the levels back to acceptable.

Diabetes
  • Type 1 and Type 2
  • People with diabetes are unable to regulate their blood glucose levels
  • Blood glucose can get too high (hyperglycemia) or too low (hypoglycemia)

Slide 38 - Slide

Diabetes type 1
  • Present from birth
  • Autoimmune - your own immune system attacks and destroys the cells in the pancreas that make insulin
  • Can't make insulin so need to inject this
  • Monitor blood glucose
  • Diet controlled

Slide 39 - Slide

Diabetes type 2
  • Gradually develops
  • Associated with lifestyle risk factors and Obesity
  • Can produce insulin
  • Cells don't respond to insulin
  • Change diet and level of exercise
  • Monitor blood glucose and can inject insulin if needed

Slide 40 - Slide

What is true for both types of diabetes?
A
Present from birth
B
Can't regulate blood glucose
C
Linked to obesity
D
Can't produce insulin

Slide 41 - Quiz

Glucagon
B
Estrogen
C
Glucose
D
Insulin

Slide 42 - Quiz

Which of the following is NOT something a person with Diabetes type 2 needs to do?
A
Monitor blood glucose
B
Do regular exercise
C
