Understanding the Pancreas and Hormone Release

Where is the pancreas located in relation to the liver?

• To the right of the liver

• In front of the liver

• Above the liver

• To the back and to the left of the liver

What type of blood does the pancreas receive from the small intestine?

• Hormone-rich blood

• Oxygen-poor venous blood

• Nutrient-rich blood

• Oxygen-rich arterial blood

What is the effect of insulin and glucagon on the liver compared to the rest of the body?

• Four times as effective

• Three times as effective

• Equally effective

• Twice as effective

What is the islet of Langerhans?

• A hormone

• A blood vessel

• A collection of cells in the pancreas

• A type of enzyme

Which cells in the pancreas release insulin?

• Delta cells

• Beta cells

• Gamma cells

• Alpha cells

What triggers the release of insulin from beta cells?

• Presence of potassium

• GLUT2 transporter

• GLUT3 transporter

• GLUT1 transporter

What is the process called when insulin is released from beta cells?

• Endocytosis

• Phagocytosis

• Exocytosis

• Pinocytosis

What is known to trigger glucagon release from alpha cells?
