Verified step by step guidance

Understand the primary functions of the kidney: The kidney is responsible for filtering blood, maintaining fluid and electrolyte balance, regulating blood pressure, and excreting waste products. It does not regulate body temperature, synthesize red blood cells, or produce digestive enzymes.

Identify the term 'excretion': Excretion refers to the process of removing waste products from the body. The kidney plays a key role in excretion by eliminating metabolic waste products through urine.

Focus on metabolic waste products: The kidney removes substances like urea, creatinine, and uric acid, which are byproducts of protein metabolism and other cellular processes.

Eliminate incorrect options: Regulation of body temperature is primarily controlled by the hypothalamus and skin. Synthesis of red blood cells occurs in the bone marrow, stimulated by erythropoietin (produced by the kidney but not an excretion function). Production of digestive enzymes is a function of the pancreas and other digestive organs.

Select the correct answer: Removal of metabolic waste products such as urea is the excretion function of the kidney.
