*Urethra- Transports urine from the urinary bladder to the exterior of the body. What are the 6 functions the kidneys provide? *Excretion (elimination of waste).
The internal urethral sphincter and the external urethral sphincter both provide muscle control for the flow of urine. The internal sphincter is involuntary. It surrounds the opening of the bladder to the urethra and relaxes to allow urine to pass. The external sphincter is voluntary.
The primary function of the detrusor muscle is to contract during urination to push the urine out of the bladder and into the urethra. The detrusor muscle will relax to allow the storage of urine in the urinary bladder.
Your kidneys, located toward the back in your upper abdomen, produce urine by filtering waste and fluid from your blood. That urine then travels through your ureters to your bladder, where the urine is stored until you can eliminate it at an appropriate time.
Urine exits the bladder and the body through the urethra. The kidneys, ureters, bladder, and urethra make up the urinary tract, the pathway through which urine flows and is eliminated from the body.
The ureters are two thick tubes which act to transport urine from the kidney to the bladder. They are approximately 25cm long and are situated bilaterally, with each ureter draining one kidney.
Some of the more common problems of the urinary system include:
- Bladder infections - (cystitis) usually caused by bacteria.
- Enlarged prostate - in men, this can make it difficult to empty the bladder.
- Incontinence - when urine leaks out of the urethra.
- Kidney infections - when a bladder infection 'backs up' the ureters.
Urine is formed in the kidneys through a filtration of blood. The urine is then passed through the ureters to the bladder, where it is stored. During urination, the urine is passed from the bladder through the urethra to the outside of the body.
Normal urine color ranges from pale yellow to deep amber — the result of a pigment called urochrome and how diluted or concentrated the urine is. Pigments and other compounds in certain foods and medications can change your urine color. Beets, berries and fava beans are among the foods most likely to affect the color.
The kidneys filter out the waste products and excess fluids from the body and dispose of them in the form of urine, via the bladder. The clean blood flows back to the other parts of the body. If your kidneys did not remove this waste, it would build up in the blood and cause damage to your body.
From the collecting ducts, the urine progresses to the renal pelvis, a widened area of the kidney, and exits through the ureter. The urine passes through the ureters to the urinary bladder.
Your kidneys, located toward the back in your upper abdomen, produce urine by filtering waste and fluid from your blood. That urine then travels through your ureters to your bladder, where the urine is stored until you can eliminate it at an appropriate time.
The cells of the body need to grow in an isotonic environment in order to maintain their fluid and electrolyte balance. The kidneys maintain the body's osmotic balance by controlling the amount of water that is filtered out of the blood and excreted into urine.
urinary system; balancing PH, water, salts, acids and bases. urinary system; regulates the volume and composition of blood through? urinary system; regulates blood pressure(via renin); makes red blood cells (erythropoietin).
Signs of a bladder problem can include:
- Inability to hold urine or leaking urine (called urinary incontinence)
- Needing to urinate eight or more times in one day.
- Waking up many times at night to urinate.
- Sudden and urgent need to urinate.
- Pain or burning before, during, or after urinating.
- Cloudy or bloody urine.
If you have an overactive bladder, you may: Feel a sudden urge to urinate that's difficult to control. Experience unintentional loss of urine immediately after an urgent need to urinate (urgency incontinence) Urinate frequently, usually eight or more times in 24 hours.
The detrusor is thicker in men than women, as greater voiding pressure is needed to empty the bladder through the longer urethra of males [7].

This stretching can increase the size of the bladder from about 2 inches to more than 6 inches long, depending on the amount of liquid. The typical human bladder reaches its capacity between 16 to 24 ounces of urine, but the urge to urinate comes when the bladder is about one-quarter full.
A healthy adult bladder can hold up to 16 ounces (2 cups) of urine comfortably, according to the National Institutes of Health. How frequently it fills depends on how much excess water your body is trying to get rid of. Circular muscles called sphincters close tightly to keep urine from leaking.
Kidney and urinary system parts and their functions
- Remove waste products and medicines from the body.
- Balance the body's fluids.
- Balance a variety of electrolytes.
- Release hormones to control blood pressure.
- Release a hormone to control red blood cell production.
- Help with bone health by controlling calcium and phosphorus.
Interstitial cystitis (IC)/bladder pain syndrome (BPS) is a chronic bladder health issue. It is a feeling of pain and pressure in the bladder area. Along with this pain are lower urinary tract symptoms which have lasted for more than 6 weeks, without having an infection or other clear causes.
The bladder expands when it fills up, like a balloon. Nerves in the bladder wall detect the expansion and send a signal to the brain, letting it know that the bladder is full.
