The urinary bladder is part of the excretory system. The excretory system is composed of the kidneys, ureters, bladder, and urethra. It's function is to remove urea and other compounds from the body, and to maintain the balance of salts and pH in the body. The urinary bladder, commonly just called the bladder, is located behind the pelvic bone and may protrude into the abdomen when full. It's function is to store urine (commonly called "pee") until there is an opportunity to empty the bladder via the urethra.
To urinate, if you mean the urinary bladder. If you mean the swim bladder, it is to be able to change its depth in the water. It has a way to vent air from the gills to the swim bladder, and from the swim bladder to the digestive tract. So the fish would inflate the bladder to be able to rise and deflate the bladder to go lower.
This condition is known as Pneumaturia which can be a symptom of diseases such as Diverticulitis, Crohn's, or cancer of the bladder or colon. Another cause may be a rare form of Urinary Tract Infection known as Emphysematous cystitis. Alleviating the symptom of gases (air) in the bladder is greatly dependent on identifying and treating the underlying cause. It is a serious symptom in any case. Please see a doctor.
My mother was recently told that she has air in her bladder. Her doctor said that there are two ways that air can get into the bladder. One is when a catheter is inserted air can go in with it. The other is a fistula between the colon and bladder that allows air to enter from the colon into the bladder. I have since seen an article that says that bladder infections can sometimes cause gas (air) to build up in the bladder. Hope this helps!
air bladder is present which regulates buoyancy
No
The Fucus is the a brown algae seaweed that comes with an air bladder. The bladder is filled with oxygen, nitrogen and carbon dioxide.
to hold air
no, they have a swim bladder but this is so the fish can stay afloat
Mine came new with air pressure in the bladder & no water in the unit so I would assume that you would pressurize the bladder with no water in the unit . Hope this helps .
It is a bladder of air.
A ballon because when you blow it up with air it floats like a fish bladder and when you let out the air it sinks like a fish bladder.
