How it helps to Maintain homeostasis

The ureters, urinary bladder, and urethra together form the urinary tract, which acts as a plumbing system to drain urine from the kidneys, store it, and then release it during urination. Besides filtering and eliminating wastes from the body, the urinary system also maintains the homeostasis of water, ions, pH, blood pressure, calcium and red blood cells

Urinary systems relatives

The urinary system like all systems in your human body doesn't work alone. It has an interdependent relationship with the endocrine system, the circulatory system, the musculoskeletal system and the nervous system. The adrenal glands, also a part of the endocrine system, secrete a chemical substance that allows the kidneys to effectively regulate fluids in the body. This process is directly related to blood pressure and the circulatory system. The urinary system is also closely related to the circulatory system by virtue of the processes of cleansing the blood of waste, removing excess fluids and generally keeping other fluids in balance. The nervous and musculoskeletal systems also play a part. They work in concert with the urinary system to regulate the release of urine. Children still in diapers haven't developed these systems fully. The bladder is a muscle that can expand and contract as necessary to release urine. When the bladder is full, the nervous system receives messages that it is time to use the bathroom. The muscles in the bladder and urethra help us to hold it when no bathroom is around.

Problems that could occur

Sometimes bacteria escape the bladder and urethra traveling up the ureters to one or both kidneys. Pyelonephritis is a serious kidney infection that can spread to the blood, causing severe illness. Fortunately, pyelonephritis is almost always curable with antibiotics. The urethra is much shorter in women than in men, which is one reason why women are more open to receive UT's and pyelonephritis
