Urine

Definition

Urine is a liquid waste product formed by the kidneys that contains various metabolites, electrolytes, and waste substances filtered from the blood. It serves as a crucial medium for assessing metabolic processes and health status, making it particularly significant in the analysis of biochemical data.
