Question

Give scientific terms for the act of passing out urine?

Answer 1

The urine is the waste which is made by the kidneys, is collected in the urinary bladder through the ureter and excreted to the outside is called urination. Human adults excrete around 1.5 litres of urine in a day. The act of urination is controlled by the nervous system.

Complete answer:
The urine is the waste that consists of nitrogenous waste, salts, and urea, which is filtered from our blood with the help of kidneys. The nephrons are the structural and functional units of the kidney. Their function is filtration, secretion, reabsorption of the waste and water from the blood. The urine is collected in the urinary bladder and is released outside under the control of the brain. The act of passing urine is known as micturition.

Micturition is the process in which the urine is released to the outside from the urinary bladder. The process of micturition is controlled by the brain. It is a voluntary process that is under our control. Once the urine accumulates in the bladder, the muscular walls of the bladder expand. This stimulates the sensory nerves present in the bladder and a reflex action is generated. This reflex urges urine. The process of discharging urine is controlled by the sphincter muscles in the urethra. These sphincter muscles relax and this leads to the contraction of the bladder. This pushes the urine out of the bladder.

The scientific term for passing out urine is Micturition.

Note: The act of micturition is a discomforting process. The signal is sent by the brain for urination till the bladder empties. In some cases, many males and females shiver during urination. Urinary incontinence is a clinical problem in which the person is unable to hold the urine.
