When urine is produced by the kidneys, it travels down the ureters to the bladder, where it is stored.

The bladder has four layers. From the inside out, the epithelium is the first layer on the inside of the bladder. It acts as a lining for the bladder. The lamina propria is the next layer.

It consists of connective tissue, muscle and blood vessels. Wrapped around the lamina propria is the layer called the muscularis propria or detrusor muscle. According to John Hopkins Pathology , this layer consists of thick, smooth muscle bundles.

The final, outer layer is the perivesical soft tissue, which is made up of fat, fibrous tissue and blood vessels. The other parts of the bladder are located at the bottom of the sack. An opening at the bottom of the bladder is connected to the urethra.

A circular, muscular sphincter pinches tight to keep the opening and the urethra from leaking urine. When a person urinates, the detrusor muscles contract to squeeze the urine out of the bladder while the sphincter relaxes to open the opening of the bladder and urethra. The opening at the bottom of the bladder empties urine into the urethra, where it then empties from the body.

Many diseases and conditions can originate in the bladder. Leakage and frequent urges often are caused by the decreased capacity of the bladder and overactivity of the bladder. An overactive bladder can be caused by a wide range of conditions, including constipation and excess caffeine in the system, according to the Mayo Clinic. The organs of the urinary system include the kidneys, renal pelvis, ureters, bladder and urethra.

The body takes nutrients from food and converts them to energy. After the body has taken the food components that it needs, waste products are left behind in the bowel and in the blood. The kidney and urinary systems help the body to eliminate liquid waste called urea, and to keep chemicals, such as potassium and sodium, and water in balance.

Urea is produced when foods containing protein, such as meat, poultry, and certain vegetables, are broken down in the body. Urea is carried in the bloodstream to the kidneys, where it is removed along with water and other wastes in the form of urine.

Other important functions of the kidneys include blood pressure regulation and the production of erythropoietin, which controls red blood cell production in the bone marrow. Kidneys also regulate the acid-base balance and conserve fluids. Two kidneys. This pair of purplish-brown organs is located below the ribs toward the middle of the back. Their function is to:. The kidneys remove urea from the blood through tiny filtering units called nephrons.
