Which function is NOT associated with the kidneys?

The function that is not associated with the kidneys is the storage of glycogen. The primary roles of the kidneys include water reabsorption, which helps maintain fluid balance in the body; the production of hormones such as erythropoietin for red blood cell production; and the regulation of blood pressure through the renin-angiotensin-aldosterone system.

In contrast, glycogen storage is primarily a function of the liver and muscle tissues. The liver stores glycogen as a form of energy reserve, which the body can mobilize when needed. The kidneys, while involved in various metabolic processes, do not serve as a site for glycogen storage or management. Understanding the specific functions of each organ helps clarify why glycogen storage is unrelated to the kidneys’ roles in the body.
