Frequency of urination is called _____________.
Urination is the release of urine containing urea as a nitrogenous waste from the body by the urinary system. The urinary system consists of the urinary tract organs - kidneys, ureters, urinary bladder and urethra. Urine travels down from the kidneys to two thin tubes called ureters to the bladder. The bladder stores urine until urination.
Kidneys - A pair of kidneys are located below the ribs towards the middle of the back. The kidneys have tiny filtering units called nephrons which are composed of renal corpuscle and a renal tubule.
Ureters - Two narrow tubes carry urine from the kidneys to the urinary bladder.
Urinary bladder - Muscular sac organ located in the pelvis that stores urine from the kidneys before excretion by urination via the urethra.
Urethra - Its a tube-like duct that allows the passage of urine outside the body. The sphincter muscles of urethra are controlled by the brain for voluntary and involuntary urination.
