Our body is made up of several organs. Each organ has been assigned a specific task. Some organs work under the respiratory system, while some work under the digestive system. Our body also consists of few urinary organs that help in the secretion of body wastes. The urinary tract system is responsible for eliminating liquid waste products from the body.

The urinary system consists of four organs that are kidneys, ureters, urinary bladder and urethra. Each of these organs performs a specified task. They are located below the ribs and produce erythropoietin, a hormone that produces red blood cells inside the bone marrow.

The kidney belongs to the upper urinary tract system and filters the body waste from the bloodstreams. This waste is converted into urine for the secretion. This urinary tract organ also filters out excess body nutrients for the excretory process. The kidneys are connected to two ureters. This tube like structure transports the filtered urine into the urinary bladder.

As soon as, the urine enters the urinary bladder, it is stored inside an elastic bag for secretion. The bladder expands itself till it is completely filled with urine. The urinary bladder is surrounded by controlled and uncontrolled sphincter muscles that initiates and prevents leakage of urine. Initially, the bladder is half full and waits till the urine gets filled completely.

Once, the bladder gets filled with the urine, the brain sends impulses to the internal sphincter muscle to relax and let the urine flow into the urethra. Hence, the person feels the urge to urinate and heads to the washroom. Now, the external sphincter muscles are relaxed as soon as the individual is ready to secrete. Hence, the urethra opens and excretes the body waste.

Thus, the urinary tract system works in coordination to support effective functioning of the human body.
