URiNARY TRACT

Urinary tract it is written in the Holy King James Bible epistle to the Ephesians of saint Paul the apostle 50 AD Anno Domini in the year of our Lord Jesus Christ 1 Corinthians 15:43-44 It is sown in dishonour; it is raised in glory: it is sown in weakness; it is raised in power: It is sown a natural body; it is raised a spiritual body. There is a natural body, and there is a spiritual body. amen Urine is mostly water (91-96%), with the remainder being urea (a protein waste product), salts (sodium, potassium), creatinine (a waste product from muscle metabolism), uric acid (a nitrogen waste product), and small amounts of other organic compounds, hormones, and metabolites. The specific composition can vary based on diet, physical activity, and overall health, with abnormal levels of certain substances like protein or blood indicating illness. The yellow color of urine is due to a pigment called urochrome. Main Components of Urine Water: Makes up the vast majority of urine, typically 91% to 96%. Urea: A nitrogenous waste product from the metabolism of proteins. Salts: Inorganic salts, including sodium, potassium, and chloride, are present as electrolytes. Creatinine: Another waste product resulting from muscle activity. Uric Acid: A nitrogenous waste product of nucleic acid breakdown. Urochrome: A pigment that gives urine its yellow color. Other Substances: Urine can also contain small amounts of hormones, metabolites, and traces of proteins. Healthy urine should be light yellow, indicating you are well-hydrated and that nothing is visibly wrong. Abnormal Components: The presence of excess protein, blood, or an unusually high amount of organic matter can be a sign of illness or kidney problems. Variations: The volume and specific composition of urine can change depending on factors like your diet, water intake, and the amount of physical exercise you do. Urine content does not contain "recycled blood" in the sense of blood cells. Instead, urine is formed by the kidneys, which filter about 150 quarts of blood daily, reabsorbing nearly all useful substances and waste products, with only about 1 to 2 quarts of the remaining fluid becoming urine to be excreted 1. Filtration: Your kidneys filter large volumes of blood, a process that removes small molecules like water, salts, and waste products 2. Reabsorption: Most of the water and necessary substances, such as glucose and electrolytes, that are filtered out of the blood are returned to the bloodstream by the renal tubules 3. Waste Excretion: The remaining fluid, which contains excess water and waste products, becomes urine and is eventually passed out of the body. Therefore, while urine originates from the filtration of blood, it does not contain significant amounts of blood cells or "recycled blood". Instead, it's primarily a liquid mixture of water and metabolic waste products that the body needs to eliminate.
