How does the urinary system clean blood?
- Each kidney is supplied with blood by several microscopic arteries.
- Kidneys extract nutrients and toxins from your blood.
- The bloodstream receives reabsorbed nutrients such as proteins, vitamins, minerals, and other foods.
- Urine and waste products are transported to your bladder through your ureters. Urine is stored in your bladder until you use the restroom.
- Urine is out from the body through the urethra.
Human Urinary System
The process of removing chemicals from the body is known as excretion. Numerous cellular reactions generate diverse excretory products such as urea, uric acid, creatinine, bilirubin, and ammonia. Protein and nucleic acid metabolismâs breakdown products are these excretory by-products. These excretory products need to be removed from the body since a build-up of them can cause a variety of diseases. The three main excretion organs are the kidneys, large intestine, and skin.
Excretory products are eliminated through a variety of methods, including:
- Sweating: Salts, carbon dioxide, urea, and ammonia are all eliminated in very minute quantities through sweat.
- Urine: Urea, uric acid, creatinine, and ammonia are excreted by the kidneys through urine. Urine is also used to eliminate extra ions including Ca2+, Na+, and phosphates. Urine is used for the excretion of numerous medications, poisons, and even too much water.
- Feces: The body excretes minute amounts of water, inorganic salts, bacteria, byproducts of bacterial decomposition, undigested substances, and indigestible food components in feces. The majority of the bilirubin in bile is processed by bacteria in the small intestine and expelled in feces.
