Verified step by step guidance

Understand the concept of homeostasis: Homeostasis refers to the body's ability to maintain a stable internal environment despite external changes. The kidneys play a critical role in this process by regulating various physiological parameters.

Identify the primary functions of the kidneys: The kidneys are responsible for filtering blood, removing waste products, balancing electrolytes, regulating blood pressure, and maintaining fluid balance. They also contribute to the production of hormones like erythropoietin, which stimulates red blood cell production.

Eliminate incorrect options: The production of digestive enzymes is a function of the pancreas, not the kidneys. Transmission of nerve impulses is primarily managed by the nervous system, not the kidneys.

Focus on the correct function: The kidneys regulate blood volume and composition by filtering blood, reabsorbing essential substances, and excreting waste products in urine. This process is vital for maintaining homeostasis in the body.

Relate the function to homeostasis: By regulating blood volume and composition, the kidneys ensure proper electrolyte balance, pH levels, and fluid distribution, which are essential for the stable functioning of cells and organs in the body.
