The urinary system is a vital organ system that helps in the removal of waste products from the body and maintain fluid balance. It’s made up of the kidneys, ureters, bladder and urethra. It’s important to note that there are several functions of the urinary system, but the following is not one of them:
- Production of hormones: Although the urinary system is responsible for the production of hormones such as erythropoietin (EPO) which helps regulate red blood cell production, it does not produce other hormones like those produced by the endocrine system such as insulin.
- Digestion: The urinary system does not have any role in the digestion process. That is the responsibility of the digestive system.
- Transport of nutrients: While the urinary system does move nutrients and other substances to the body’s cells, its goal is to move waste products away from the cells.
- Immune system functions: The urinary system does not have any role in the immune system’s activities. Immune system functions are carried out by the lymphatic system.
The primary functions of the urinary system include:
- Blood filtration: The kidneys are responsible for filtering the blood and removing waste products from it. This filtration occurs in the nephrons, which are tiny structures in the kidneys.
- Excretion of waste products: The kidneys remove waste products, such as urea, from the bloodstream and transport them to the bladder, where they are eventually excreted in the form of urine.
- Maintain fluid balance: The kidneys adjust the amount of water and electrolytes in the blood, which helps keep the body’s fluid levels in balance.
- Regulate blood pressure: The kidneys are responsible for regulating the body’s blood pressure by releasing hormones such as renin, angiotensin and aldosterone.
The urinary system is an important organ system that helps keep the body healthy. It’s important to keep it functioning properly by drinking plenty of water and eating a balanced diet. If you experience any problems with your urinary system, it’s important to seek medical advice as soon as possible.
