Urinary Bladder

Bladder The urinary bladder, or urinary bladder, is a hollow muscular organ located in the pelvic cavity. The main function of the bladder is the accumulation and storage of urine coming from the kidneys through the ureters.

The bladder is pear-shaped and consists of three layers: the mucous membrane, the muscular layer and the adventitia (outer connective tissue layer). The mucosa is lined with transitional stratified epithelium and forms folds that straighten as the bladder fills with urine.

The muscle layer consists of smooth muscle fibers - internal longitudinal and external circular. Their contractions ensure emptying and closing of the bladder.

The bladder communicates with the urethra, through which urine is expelled during urination. This process is controlled by the autonomic nervous system.

Thus, the bladder performs the important function of storing and periodically removing urine from the body. Disturbances in its functioning can lead to various diseases of the urinary system.

The urine bladder (Urinal Bladder or Bladder for short) is a natural organ in the human body that serves to collect and store urine until it is eliminated from the body. The bladder is an important organ for maintaining human health and survival, and in this article we will look at its features and functions.

The urinary bladder is an oblong sac located in the abdominal cavity, below the bladder; in men it is located behind the symphysis pubis, and in women it is slightly above the base of the symphysis between the pubic bones. The bladder has two openings, one for filling (the urethra) and the other for draining urine (the urethra). They are connected to the exit site of the central tube and the urinary canal system (kidneys, ureters).

The size of the bladder varies from the size of a walnut to the size of an average apple. It fills through the urethra and is emptied through the urethra. The bladder has a reflex innervation that controls its functioning and keeps it in the desired state. Under normal conditions, a full bladder puts pressure on the receptors, causing the urge to urinate when the bladder is full to the brim. This process can cause discomfort, burning or pain, especially with frequent, weak, but constant urination (without flow).

The important functions of the bladder are to collect urine, eliminate it from the body, protect against infection, and control urination. Its constituent elements include muscle, walls and mucous membrane. Urine usually flows through the urethra (
