What is a baby?

Latin is the language from which, etymologically speaking, the term bladder comes from, which we are now going to 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 that receives urine from the ureters and expels it out of 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 varies between 300 and 350 cubic centimeters. From this amount arises the urge to urinate. When there is urine retention, the capacity can increase to about 3 liters while, in cases of cystitis, it reaches only 50 cubic centimeters.

The bladder wall is composed of three layers: the serous layer (formed by the parietal peritoneum), the muscular 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, trigone, dome or apex of the bladder are other of the most important internal parts of the bladder, where there are also veins, nerves, lymphatic vessels and arteries. Cystoscopy provides the appropriate method for analyzing the bladder. It is an endoscopic examination that consists of introducing a tube with a video camera through the urethral meatus, allowing the doctor to observe the urethra and bladder. Among the most common diseases that occur in the human body and that affect the aforementioned bladder, we would have to highlight, for example, cystitis. It is an inflammation, at the same time temporary and chronic, which produces fever, intense pain, greater number of urination and also weakness. However, other 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 that give rise to the latter serious illness. According to studies carried out by health professionals, this serious pathology tends to affect men more than women and has increased alarmingly in recent decades. It should be noted that bladder trauma caused by violent blows or cuts can be very serious and lead to death. Other urinary injuries arise from non-violent reasons, such as cesarean section or chronic alcoholism. An injury to a full bladder can cause urine to leak into the abdomen, causing peritonitis.

In addition to all this, we cannot ignore the existence of what is known as a swim bladder. It is a membrane that different species of fish have and that helps them to stay between two types of water without the need for great efforts.
