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.
Correct Answer is A
Explanation
Type 1 diabetes mellitus is characterized by an autoimmune process in which the body's immune system destroys the pancreatic beta cells responsible for producing insulin. This results in an absolute deficiency of insulin, requiring exogenous insulin administration for glycemic control.
Incorrect choices:
b. This choice is incorrect. Type 2 diabetes mellitus is characterized by insulin resistance and impaired insulin secretion, rather than autoimmune destruction of beta cells.
c. This choice is incorrect. Gestational diabetes mellitus occurs during pregnancy and is not characterized by autoimmune destruction of beta cells.
d. This choice is incorrect. Prediabetes is a precursor to type 2 diabetes and involves impaired glucose tolerance, but it does not result from autoimmune destruction of beta cells.
