What is the bladder anatomy?
The bladder anatomy is designed to be able to hold enough urine, that an individual must only be alleviated four to six times a day. It is located in the pelvic cavity, near the small intestine and in the reproductive organs. The size and shape of the lemon, the surface of the bladder allows the organ to stretch as it is filled.
The bladder is connected to the kidneys by tubes called urea, which connect to the bladder in the urinary holes. These tubes enter the bladder across the upper part on the left and right side and pass urine into the bladder, where it is stored until elimination. During the elimination process, urine from the bladder passes through the structure at the bottom, called the urethra. At the central point between these three holes, the pale, triangular area is known as the trigonum vesicae, which is mainly used by doctors as a reference point for other parts of the bladder anatomy.
Several layers of tissue and muscle form the surface part of the bladder anatomy. The furthest layer is called serosa or peritoneum. This thin tissue is similar to tissues that line the surfaces of other organs in the abdomen, such as the kidneys and the inside of the abdomen itself. Below this thin layer of tissue is a layer that includes muscles that involuntarily control the expansion and contraction of the bladder. This layer, called a detrusor muscle, involuntarily works for expansion when urine flows from the urethors and closes because it is excluded from the body.
On the inside of the bladder is a mucous membrane that has elastic properties and forms of fold when the bladder is empty. It is attached to the outer layer of the muscle layer by a structure called a sub-mkys layer. This layer shares the same elasticity as the other layers of the bladder.
muscle That keeps urine in the bladder, is known as an inner urethral sphincter. It is this valve that opens during the elimination process to allow urine to go through. In some individuals, incontinence is caused by a failure of this valve.
The bladder anatomy is a simple structure that works on a predominantly involuntary basis to allow individuals to wait for hours between removing the urine from the body. The basic bladder anatomy is the same in men and women, with the length of the urethra the main difference. The size and shape of the bladder can change as an individual and may have the less older one that one gets.
