Renal System
The Renal System, also known as the Urinary System, is a group of organs in the body that are responsible for the production, storage, and elimination of urine. It includes two kidneys, two ureters, the bladder, and the urethra. The kidneys filter the blood to remove waste products and produce urine. The urine is then transported through the ureters to the bladder, where it is stored until it is eliminated from the body through the urethra.
Structure[edit | edit source]
The renal system is composed of the following organs:
- Kidneys: These are bean-shaped organs located on either side of the spine, below the rib cage. Each kidney contains around a million tiny structures called nephrons, which filter the blood to produce urine.
- Ureters: These are tubes that carry urine from the kidneys to the bladder.
- Bladder: This is a hollow organ that stores urine until it is ready to be eliminated from the body.
- Urethra: This is the tube through which urine is expelled from the body.
Function[edit | edit source]
The primary function of the renal system is to filter the blood and remove waste products. This is accomplished through a complex process that involves filtration, reabsorption, secretion, and excretion. The kidneys also play a crucial role in maintaining the body's electrolyte balance and regulating blood pressure.
Diseases and Disorders[edit | edit source]
There are many diseases and disorders that can affect the renal system, including:
- Kidney disease: This can be caused by conditions such as diabetes and high blood pressure.
- Urinary tract infection: This is an infection that can occur anywhere along the urinary tract.
- Kidney stones: These are hard deposits of minerals and salts that form inside the kidneys.
- Bladder cancer: This is a type of cancer that begins in the cells of the bladder.
