Latin is the language from which it comes, etymologically speaking, the term bladder that we will now analyze in depth. In this sense, we can say that it emanates from the word vesica, which in turn is based on a root of Indo-European origin.
The bladder is the organ who receives the urine of the ureters and expels it outside the body through the urethra. This muscular and membranous organ is part of the urinary system of all mammals and acts as a kind of bag to store the urine produced by the kidneys.
The normal physiological capacity of the bladder ranges between 300 and 350 cubic centimeters. From this amount, the desire to urinate arises. When the urinary retention , the capacity can be increased up to about 3 liters while, in the cases of cystitis , barely reaches 50 cubic centimeters.
The bladder wall is composed of three layers: the serous layer (formed by the parietal peritoneum), the muscle layer (with a smooth muscle that contracts during the expulsion of urine) and the mucous layer (which has a urinary transition epithelium and a sheet of connective tissue).
The bladder neck, the trigone, the bladder dome or the apex are other of the most important interior parts that the bladder has where there are also no veins, nerves, lymphatics and arteries.
The cystoscopy Offers the appropriate method for bladder analysis. It is an endoscopic examination that involves the introduction of a tube with a video camera through the urethral meatus, allowing the doctor Look at the urethra and bladder.
Among the most common diseases that occur in the body of the human being and that affect the aforementioned bladder we should highlight, for example, cystitis. This is an inflammation, both temporary and chronic, of that which produces fever, severe pain, a greater number of urination and weakness.
However, more pathologies that affect this part of the body are incontinence, which would be the loss of absolute bladder control, and bladder cancer. Frequent consumption of tobacco or coffee as well as certain chemicals, various drugs or radiation in the pelvic area are other causes of the latter serious illness.
According to studies carried out by professionals in the health field, this severe pathology usually affects men more than women and has been alarmingly increased in recent decades.
It should be noted that bladder trauma violent blows or sharp wounds can be very serious and lead to death. Other bladder injuries arise for non-violent reasons, such as performing a C-section or chronic alcoholism. A full bladder injury can cause a leak of urine into the abdomen , causing a peritonitis .
In addition to all of the above, we cannot ignore the existence of what is known as the swim bladder. It is a membrane that have different species of fish and that helps them stay between two types of water without major efforts.
