Function of the Urinary System

The function of the urinary system may seem simple but the process is complex and important to your overall health. The kidneys, ureters, bladder, and urethra all contribute to the urinary process, each with their own function and purpose. These organs work together to remove waste from the body, maintain the balance of acids and bases, and regulate hydration.

Home Remedies for the Urinary System

For treatment of issues with the urinary system, you may find home remedies quite beneficial. The areas and problems of the urinary system that may respond favorably to home remedies include:

How the Urinary System Works


After you eat and drink, your body breaks down the consumed particles and separates the nutrients from the waste. The waste products go into the rectum and the blood, where the urinary system steps in and removes urea, a harmful waste byproduct that goes into the blood during the digestion process. When the blood passes through the kidneys, a filtration process occurs that removes the urea from the blood into the kidneys.

As a function of the urinary system, the kidneys use nephrons to remove the urea. Each nephron contains a ball of capillaries, known as a glomerulus, along with a renal tubule. These components work to form urine by combining urea, water and other waste materials, which passes through the nephrons, then down the renal tubules.

Once the kidneys finish processing the waste and create urine, they pass the fluid to the ureters, two thin tubes that connect to the bladder. The ureters contract to push the urine away from the kidneys, which prevents an infection from forming.

The other role the ureters play in the function of the urinary system is to empty small amounts of urine into the bladder every few seconds. The bladder than stores the urine until it is full, at which time neurons send a signal to your brain letting you know to go to the bathroom.

When you urinate, the brain sends signals back to the bladder, letting it know to tighten it muscles. The brain also sends a signal to the sphincter muscles telling them to relax. Both of these messages allow the urine to flow freely from the bladder to the urethra, exiting the body.

Differences between Men and Women

The female and male urinary systems have the same organs and the same function but there is a slight difference. The female urinary system is separate from the reproductive system, as urine has its own exit and the urethra has no attachment to any reproductive organs. In the male urinary system, there is only one exit for sperm and urine. The reproductive and urinary systems share the penis and the urethra, which is longer than the urethra in the female body. The function of the urethra in the male reproductive system is to assist in the release of semen during ejaculation and releases urine as a function of the urinary system.

Ailments of the Urinary System

Urinary system diseases vary from common and treatable to uncommon and life threatening. Some conditions that can affect the urinary system include:

  • Benign Prostatic Hyperplasia: enlargement of the prostate gland that causes blockage by squeezing the urethra, making it difficult to go to the bathroom.

  • Painful Bladder Syndrome: chronic condition that occurs when the bladder wall becomes inflamed and irritated, which leads to scarring of the bladder, bleeding at the site, and ulcers. This can prevent the proper function of the urinary system.

  • Kidney stones: calcium build up that creates various size stones in the urinary system. Some stones are small enough to pass through the urethra while others require surgery.

  • Proteinuria: high levels of protein in the urine, which may be a sign that the kidneys are not properly functioning.

  • Kidney Failure: occurs when the kidneys cannot remove urea from the blood or regulate the amount of water in the body. Happens gradually or suddenly.

  • Urinary Tract Infections: bacteria enter the urethra and cause an infection. This problem is more common in women than men and treatment takes the form of antibiotics.

These disorders are harmful to the urinary system, and possibly the rest of the body, if left untreated.

The function of the urinary system focuses on two small but important details crucial to your health. It is vital to maintain the health of this system as it can easily affect the other organs and processes that occur within the body. If you suspect that you have a problem with this part of your body, consult with your physician.
