Explanation

The liver plays a central role in blood glucose regulation by releasing glucose into the bloodstream through glycogenolysis and gluconeogenesis when blood glucose levels are low. It also stores glucose as glycogen and responds to insulin and glucagon signals.

Incorrect choices:

b. This choice is incorrect. While the kidneys play a role in filtering blood and excreting waste products, they are not primarily responsible for regulating blood glucose levels.

c. This choice is incorrect. The lungs are involved in oxygen and carbon dioxide exchange and are not directly involved in blood glucose regulation.

d. This choice is incorrect. The spleen is involved in immune function and blood filtration, but it does not play a central role in blood glucose regulation.

A. Diabetic ketoacidosis (DKA). B. Diabetic nephropathy. C. Diabetic neuropathy. D. Diabetic retinopathy.

Incorrect choices:

a. This choice is incorrect. Diabetic ketoacidosis (DKA) is an acute complication characterized by high blood glucose levels, ketosis, and metabolic acidosis.

c. This choice is incorrect. Diabetic neuropathy refers to nerve damage due to diabetes and can cause symptoms such as tingling, pain, and loss of sensation in the extremities.
