Artificial pancreas: how it works

The video explains how the pancreas regulates blood sugar levels by releasing insulin when blood sugar is high and glucagon when it is low. It also describes the concept of an artificial pancreas, which uses sensors to monitor glucose levels and a pump to dispense insulin and glucagon as needed to maintain stable blood sugar levels.

What hormone is released by the pancreas to lower high blood sugar levels?

• Cortisol

• Insulin

• Glucagon

• Adrenaline

When blood sugar levels are low, which hormone does the pancreas release?

• Thyroxine

• Glucagon

• Insulin

• Melatonin

What is the primary function of glucagon in blood sugar regulation?

• To release glucose into the bloodstream

• To decrease glucose production

• To convert glucose into glycogen

• To increase glucose uptake by cells

What does an artificial pancreas use to monitor glucose levels in real-time?

• A thermometer

• A sensor

• A stethoscope

• A barometer

How does an artificial pancreas maintain steady glucose levels?

• By reducing food intake

• By increasing physical activity

• By using a pump to dispense insulin and glucagon

• By storing excess glucose
