Blood glucose concentration Flashcards
1
Q
What organs control blood glucose concentration?
A
The pancreas and liver.
2
Q
What does insulin do?
A
Decreases blood glucose concentration.
3
Q
What does glucagon do?
A
Increases blood glucose concentration.
4
Q
What happens when blood glucose concentration increases?
A
The pancrease secretes insulin into the blood. Insulin reaches the liver and causes it to absorb more glucose from the blood.
5
Q
What happens to the glucose absorbed by the liver?
A
Some is converted into glycogen(insoluble polysaccharide) and stored in the liver. Some is used in respiration
6
Q
What happens when blood glucose decreases?
A
Pancrease secretes glucagon into the blood. When glucagon reaches the liver, liver cells break down glycogen to glucose and release it into the blood.
