Verified step by step guidance

Understand the primary functions of the kidney. The kidneys are vital organs responsible for filtering blood, removing waste, balancing electrolytes, and regulating blood pressure.

Recognize that the production of insulin is a function of the pancreas, not the kidneys. Insulin is a hormone that regulates blood sugar levels.

Identify that the synthesis of vitamin D involves the skin, liver, and kidneys. The kidneys convert calcidiol into calcitriol, the active form of vitamin D, but this is not their primary function.

Note that digestion of proteins occurs in the stomach and small intestine, not in the kidneys. The kidneys do not play a direct role in protein digestion.

Focus on the regulation of blood pressure as a key function of the kidneys. They achieve this through the renin-angiotensin-aldosterone system, which helps control blood volume and pressure.
