What does the bladder contain which allow it to extend when full?

On average, your bladder can hold 400 to 600ml of urine for up to about five hours. The muscle in your bladder wall is called the detrusor muscle. The detrusor muscle relaxes to allow your bladder to fill. When you go to the toilet, it contracts to squeeze out urine.

Which tissue does the bladder have that allows it to stretch?

Unlike the mucosa of other hollow organs, the urinary bladder is lined with transitional epithelial tissue that is able to stretch significantly to accommodate large volumes of urine. The transitional epithelium also provides protection to the underlying tissues from acidic or alkaline urine.

How do they stretch your bladder?

Bladder stretching occurs when a doctor stretches your bladder by filling it with fluid. You will be given a local or general anesthesia link to help you tolerate the bladder stretching. Some people have temporary relief of their symptoms after this treatment.

What causes contraction of the bladder?

The brain signals the bladder muscle when it is time to tighten (contract) and release urine. However, certain nervous system disorders cause damage to the nerves that send signals between the brain and the bladder. When this happens, the bladder does not work properly.

How quickly can you fill your bladder?

A healthy bladder can hold about 2 cups of urine before it’s considered full. It takes your body 9 to 10 hours to produce 2 cups of urine….Pee table.

Age Average bladder size Time to fill bladder
Adult 16–24 ounces 8–9 hours (2 ounces per hour)

Does the bladder expand when full?

The Bladder Expands As It Fills with Urine The bladder is shaped like a pyramid when empty. It becomes more oval as it fills with urine and expands. A smooth muscle called the detrusor surrounds the bladder, and folds called rugae line the interior wall.

Does the bladder have a sphincter?

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. It surrounds the urethra outside the bladder and must be relaxed for urination to occur.

What happens if you stretch your bladder?

Bladder stretching In the long term, regularly holding in pee can cause the bladder to stretch. This may make it difficult or impossible for the bladder to contract and release pee normally. If a person has a stretched bladder, extra measures, such as a catheter, may be necessary.

Why do you need an expansion bladder in a tank?

The bladder separates the expanded water from air. This way, the water does not come into contact with tank and it prevents corrosion by oxygen and rusting. It also increases the pump life by reducing the number of pump cycles.

How does a pre charged bladder tank work?

It uses compressed air to adjust with the pressure changes by eliminating or accepting the water volume changes as it expands or contracts due to heating and cooling. A pre-charged bladder tank is an expansion tank which is already charged with air.

Why is it necessary to increase bladder capacity?

Bladder capacity and compliance are increased by bladder augmentation. Indicators that augmentation is necessary include clinical symptoms, such as incontinence caused by bladder dysfunction unresponsive to medical therapy, and upper urinary tract deterioration due to inadequate low-pressure storage volume.

What makes the walls of the urinary bladder elastic?

Transitional epithelium, elastic fibers, and visceral muscle tissue in the walls of the urinary bladder contribute to its distensibility and elasticity, allowing it to easily stretch and return to its original size several times each day.

How big is the bladder?

WebMD says that the normal capacity of an adult bladder is about 400 to 600 milliliters. Since the bladder is lined with layers of muscles, it is able to stretch to accommodate urine.

What is the average bladder capacity for men?

The normal capacity of the bladder is 400-600 mL. During urination, the bladder muscles squeeze, and two sphincters (valves) open to allow urine to flow out. Urine exits the bladder into the urethra, which carries urine out of the body. Because it passes through the penis, the urethra is longer in men (8 inches) than in women (1.5 inches).

What is the function of the female bladder?

The triangle-shaped base of the bladder, known as the trigone, helps prevent stretching of the urethra or backflow into the ureters. When signaled, the bladder releases urine through the urethra, the tube that carries urine out of the body. In women, this tube ends between the clitoris and the vagina.

Where is the female bladder located?

Generally speaking the bladder is located in the pelvic area. In males, the bottom of the bladder is positioned between the rectum and the pubic symphysis (the joint that unites the left and right pubic bones), above the prostate gland. In females, the bladder is positioned under the uterus, in front of the vagina and behind the pubic symphysis.
