urinën

Urine is a liquid byproduct of the body secreted by the kidneys through a process called urination. It is composed primarily of water, but also contains dissolved waste products, salts, and urea, a nitrogenous compound produced from the breakdown of proteins. The color of urine can vary from pale yellow to dark amber, depending on hydration levels and the concentration of urochrome, a pigment derived from the breakdown of hemoglobin. Its odor is typically mild but can change due to diet, medications, or certain medical conditions.

The primary function of urine is to remove waste products and excess substances from the bloodstream, maintaining the body's fluid and electrolyte balance. This includes filtering out toxins, excess salts, and metabolic byproducts that the body cannot reuse. The kidneys play a crucial role in this filtration process, reabsorbing essential nutrients and water while concentrating waste into urine. This urine then travels through the ureters to the bladder, where it is stored until it is expelled from the body through the urethra.

Analysis of urine, known as urinalysis, is a common diagnostic tool used in healthcare. It can provide valuable information about kidney function, urinary tract infections, metabolic disorders like diabetes, and the presence of certain drugs or toxins. Changes in urine volume, color, clarity, or odor can sometimes be early indicators of health issues.
