A level - Pancreas

Which cells in the pancreas are responsible for the production of insulin?

• Alpha cells

• Beta cells

• Delta cells

• Gamma cells

Answer explanation

Beta cells in the pancreas are responsible for the production of insulin.

What is the primary function of insulin in the body?

• To increase blood glucose levels

• To decrease blood calcium levels

• To decrease blood glucose levels

• To increase blood pressure

Answer explanation

The primary function of insulin in the body is to decrease blood glucose levels.

Which hormone is released by the pancreas to increase blood glucose levels?

• Insulin

• Somatostatin

• Glucagon

• Gastrin

Answer explanation

Glucagon is released by the pancreas to increase blood glucose levels.

What triggers the release of glucagon from the pancreas?

• High blood glucose levels

• High blood amino acid levels

• Low blood glucose levels

• Low blood calcium levels

Answer explanation

Glucagon is released from the pancreas in response to low blood glucose levels.

Which type of diabetes is characterized by an autoimmune destruction of pancreatic beta cells?

• Type 1 diabetes

• Type 1 diabetes mellitus

• Type 2 diabetes mellitus

• Gestational diabetes

Answer explanation

Which one below is an enzyme produced by acini in pancreas?

• Trypsinogen

• glucagon

• glycogen

• Insulin

Answer explanation

Trypsinogen is an enzyme produced by acini in the pancreas, making it the correct choice.

Which part of the pancreas has an exocrine function?

• Islets of Langerhans

• Acinar cells

• Beta cells

• Alpha cells

Answer explanation

Acinar cells in the pancreas have an exocrine function, secreting digestive enzymes into the pancreatic ducts.

What is the main function of the pancreatic acinar cells?

• Secretion of insulin

• Production of digestive enzymes

• Regulation of blood glucose levels

• Secretion of glucagon

Answer explanation

The main function of the pancreatic acinar cells is the production of digestive enzymes.

In response to which condition would the pancreas secrete more insulin?

• Hypoglycemia

• Hypercalcemia

• Hyperglycemia

• Hypocalcemia

Answer explanation

In response to hyperglycemia, the pancreas secretes more insulin to help lower blood sugar levels by facilitating glucose uptake into cells.

Where are the Islets of Langerhans located?

• In the liver

• In the spleen

• In the pancreas

• In the adrenal glands

Answer explanation

The Islets of Langerhans are located in the pancreas, making it the correct choice.
