Blood Glucose Homeostasis

How does the pancreas play a crucial role in blood glucose regulation?

• The pancreas secretes bile to help regulate blood glucose.

• The pancreas regulates blood glucose by producing red blood cells.

• The pancreas secretes insulin and glucagon hormones to regulate blood glucose levels.

• The pancreas releases adrenaline to control blood glucose levels.

• Promote bone growth

• Regulate blood glucose levels

• Regulate body temperature

Explain the role of glucagon in regulating blood glucose levels.

• Glucagon increases blood glucose levels by promoting glycogen breakdown in the liver.

• Glucagon promotes insulin secretion to regulate blood glucose levels.

• Glucagon has no impact on blood glucose levels.

• Glucagon decreases blood glucose levels by inhibiting glycogen breakdown in the liver.

Describe how blood glucose levels are regulated in the body.

• Blood glucose levels are regulated by the brain alone

• Insulin signals cells to release glucose from the blood when levels are high

• Insulin signals cells to take up glucose from the blood when levels are high, while glucagon signals the liver to release stored glucose when levels are low.

• Glucagon signals the liver to store glucose when levels are low

• Glucagon release

• Blood sugar increase

• Adrenaline secretion

Why is insulin important for maintaining blood glucose homeostasis?

• Insulin causes insulin resistance

• Insulin increases blood glucose levels

• Insulin regulates glucose uptake, storage, and production in the body.

• Insulin has no impact on blood glucose regulation

• Low blood glucose levels

• Consuming carbohydrates

• High blood glucose levels

How does the body respond to high blood glucose levels?

• The body responds to high blood glucose levels by increasing glucose intake.

• The body responds to high blood glucose levels by releasing insulin to help cells absorb glucose.

• The body responds to high blood glucose levels by releasing glucagon to lower glucose levels.

• High blood glucose levels have no impact on the body's response.

• Decreased thirst

• Infrequent urination

• Increased energy levels
