Mainly the urinary sphincters prevent the backflow of urine backwards into the bladder and the kidneys. Sphincters allow one-way flow and to prevent leakage (or in other words, prevent accidental urine loss).
Yes, a urethral sphincter controls the release of urine. This is a "flap" that is found between the kidneys and urethra that opens and closes to keep urine in, or let it down to be urinated out.
The cardiac (entry) and the pyloric (exit) sphincters.

Tears, breathing, urine, sweat, faeces.
Urine exits the male body through the urethra, which passes through the penis.
It is what allows things to enter and exit the cell
a ring of muscle that controls the release of an organs products. EXAMPLE: Pyloric Sphincter controls release of chyme. Cardiac Sphincter controls deposition of food into the stomach from the esophagus. External Urethral Sphincter controls release of urine. External Anal Sphincter controls release of defecation.
The duodenum has a sphincter that controls the opening of the stomach to dump partially digested food into the small intestines. This sphincter can be weakened by stomach ulcers. After the duodenum, food stuffs continues through the small intestines where most digestion takes place.
The circular ring of muscle located at the entrance and exit of the stomach is referred to as a "sphincter" - the one at the entrance to the stomach is referred to as the cardiac sphincter, and the one at the exit of the stomach to the small intestines is referred to as the pyloric sphincter.
SHUTTER in Camera controls the amount and time of light that the Sensor will exposed to.

Yes, The pyloric sphincter valve regulates the exit of digested food from the stomach to the small intestine.

How would you get the two mixed?? Just because they use the same exit from the body ie the urethra, they are produced and stored in separate parts of the body and during sex the sphincter at the exit of the bladder is tightly closed.... this is why it is so difficult to pee if you have an erection
The pyloric sphincter valve.
The cardiac (entry) and the pyloric (exit) sphincters.
The cardiac sphincter is located at the top of the stomach and controls the direction of food passing through the esophagus so that no food will re enter the esophagus. The Pyloric sphincter stops bile and digested food from entering the stomach, this valve is located at the bottom of the stomach.
A sphincter is basically a hatch keeping stuff in and other stuff out of an organ such as the stomach. The pylorus is the muscle keeping the exit of the stomach shut, or opening it so that half-digested food may enter the duodenum to be digested further. The muscle ensures food can stay in the stomach long enough, and not flow right on through without being modified long enough by the stomach acids and digestive enzymes. It also regulates the amount of stuff that goes through.
