Verified step by step guidance

Understand the function of the kidneys: The kidneys are responsible for filtering blood to remove waste products and excess substances, including water, from the body.

Identify the process of filtration: Blood enters the kidneys through the renal arteries, where it is filtered in the nephrons, the functional units of the kidneys.

Recognize the formation of urine: During filtration, waste products such as urea, creatinine, and excess ions are removed from the blood, along with excess water, forming urine.

Consider the role of urine: Urine is the liquid waste product that is excreted from the body, containing the filtered waste and excess substances.

Differentiate urine from other excretions: Unlike sweat, bile, or lymph, urine is specifically formed in the kidneys as a result of blood filtration and is excreted through the urinary system.
