How does insulin regulate glucose levels in the blood?

Back

Insulin lowers blood glucose levels by promoting glucose uptake in cells and inhibiting glucose production in the liver.

Front

Describe one method the body uses to regulate temperature.

Back

Sweating

Front

How does the pancreas contribute to glucose regulation?

Back

The pancreas regulates glucose levels by producing insulin and glucagon.

Front

What role do kidneys play in osmoregulation?

Back

The kidneys play a crucial role in osmoregulation by controlling water and electrolyte balance in the body.

Front

How does the body respond to overheating?

Back

The body cools down by increasing blood flow to the skin and sweating.

Front

What is the significance of maintaining homeostasis?

Back

Maintaining homeostasis is significant because it ensures the stability of the internal environment, allowing for optimal functioning of biological processes.

Front

What triggers the release of insulin?

Back

Elevated blood glucose levels.

Front

Describe how the hypothalamus is involved in thermoregulation.

Back

The hypothalamus regulates body temperature by initiating responses to maintain homeostasis.

Front

What is the effect of dehydration on osmoregulation?

Back

Dehydration disrupts osmoregulation by increasing solute concentration, prompting thirst and ADH release to conserve water.

Front

What is the function of glucagon in glucose metabolism?

Back

Glucagon raises blood glucose levels by stimulating the liver to release stored glucose.
