How Does The Bladder In The Human Body Work?

You know you have one, but how exactly does your bladder work to keep your body functioning properly? Think of this organ as such like a stomach where it can expand and is a sac like form. This contracts together when it has no content and expands out when it gets full of liquid. The ureters are two tube like structures that provide the fluid flow into the bladder. They expel urine from the kidneys organs down to the bladder organ. Once the bladder gets fuller the walls thin out and the organ moves upward toward the abdomen.

When your bladder starts to fill up it can increase its size up to six inches. Most bladders reach their maximum capacity between sixteen and twenty-four ounces. However, your body doesn’t wait until your bladder is full before it signals to your brain that you have to use the bathroom. In fact, when the bladder is a quarter full it will signal to your body it’s time to go.

So this begs the question, how does the urine stay in your bladder and not leak out. There is an internal sphincter. This is a sort of muscular valve the keeps the urine in the bladder and protects against leakage. It is in the form of a triangle and is found at the base of the bladder. When the body gives it’s go ahead signal the valve allows the urine to pass down through the urethra. This is the tube the connects the bladder to the outside of the body.


This is how a normal bladder works. If you have urinary tract infections or other urinary diseases your body may alter from this process. In most cases, people who have an overactive bladder tend to not be able to properly stop the signals to their internal sphincter muscle and this causes unwanted urine leakage. This is when it’s necessary to use a bladder support supplement to keep your body healthy.
