Peeing is one way our bodies get rid of waste products. The process starts in the kidneys , which remove excess fluids and waste from the blood and turn them into urine.
Frequent urination: Causes, symptoms, and treatment
Urination is the release of urine from the urinary bladder through the urethra to the outside of the body. It is the urinary system 's form of excretion. It is also known medically as micturition , voiding , uresis , or, rarely, emiction , and known colloquially by various names including peeing , weeing , and pissing. In healthy humans and many other animals the process of urination is under voluntary control. In infants, some elderly individuals, and those with neurological injury, urination may occur as a reflex.
Shivering is an involuntary response to coldness. This tightening and relaxing of muscles in quick succession causes a slight bodily shake or tremble. This momentary cold sensation or cold jolt can rip through your body unexpectedly — sometimes starting in the spine and moving downward. It can also happen when scared or excited. This weird phenomenon is unofficially called post-micturition convulsion syndrome.
