What is Urinary System?
The Urinary System is responsible for maintaining the balance of water and electrolytes in your body by removing metabolic waste from your blood. This system is composed of several organs including the kidneys, ureters, bladder, and urethra. The kidneys are the main filter of the body, excreting unwanted substances like toxins and urea from the bloodstream. Urea is a nitrogenous waste product that comes from breaking down proteins in the body. The kidneys also regulate fluid levels in the body by reabsorbing water and releasing hormones to control blood pressure levels.The two ureters are tubes that connect each kidney to the bladder where urine collects until it needs to be expelled via urination. The bladder stores urine until it reaches a certain volume before signaling to you that it needs to be emptied through urination. The bladder is a muscular organ that stretches as more urine accumulates then contracts when emptying its contents out through another tube called the urethra which carries urine out of your body.
