Micturition - Simply stated, micturition is the need to urinate that arises once the bladder is full to a degree that it sends signals to the brain that the bladder must be emptied by peeing and the waste must be removed.

Macturition Overview

A number of systems in the body deal with the removal of waste products from the body. The urinary system is one of the systems that removes waste from the body. The waste is not removed continuously, but rather in periodic episodes of peeing. The human urinary system works by storing the waste in the bladder before eliminating the waste. Whenever the bladder becomes full to a sufficient degree, it sends signals to the brain that it should be emptied. That signal is known as macturition.

Macturition is vital to our health. The feeling of the need to urinate is at first a relatively mild one that can be tolerated, but if the person does not urinate and remove waste, the urinary urge increases as time goes on, and the feeling becomes more uncomfortable and more difficult to urinate until the person feels like he or she must absolutely urinate. This helps keep us healthy as the waste that our bodies is trying to remove does not remain in our systems for too long. Sometimes the waste is made up of harmgul bacteria that should not be allowed to stay in the system and multiply, and removing the bacteria in a timely manner can help us avoid Urinary Tract Infections (UTI).

Kidneys and Micturition

The kidneys are essential to excreting the right waste materials in the right amounts. The kidneys constantly filter the blood. The nutrients in the blood that are still needed are reabsorbed for conservation. Chemicals, substances, and water that have become unneeded by the body are filtered by the kidneys and become waste products which eventually make up the urine which we pee. The kidneys also help regulate levels of blood volume and pressure, ion concentration, pH, and red blood cell production. In fact, urine tests that show abnormal levels of various chemicals in the urine signal that the kidneys have had to remove an abnormal amount of that chemical from the blood, indicating a metabolic problem in the body.

Once the urine leaves the kidneys, it passes into the urinary bladder through the ureters. Antidiuretic hormone (ADH) and aldosterone control how much urine the body produces. The pituitary gland which is responsible for releasing hormones releases ADH if the body is dehydrated. This hormone is responsible for producing less urine by keeping more water in the bloodstream. On the other hand, if there is too much water in the body, the pituitary gland stops releasing ADH and the kidneys absorb more water from the blood and remove the excess water as waste.

Bladder and Micturition

Once the urine leaves the kidneys, it collects in the bladder. Once the urine is in the bladder, it simply collects there until there is enough urine to fill the urinary bladder to a level when it begins to become full. Once the bladder begins to become full, it sends signals to the brain that it has to be emptied by peeing. This signal is micturition and it is important to listen to your body when it tells you that you need to urinate because letting the urine sit in the bladder for a long time is dangerous. Harmful bacteria may multiply inside the bladder and that can cause Urinary Tract Infections (UTIs) or other problems since the waste materials can be toxic to the body if they stay in the body too long.

Monitoring Micturition

It is important to be aware of the state of our urine and monitor it. Since the urine is a result of what we consume going through many of our organs and making it all the way through the urinary system, it is a good barometer for what is going on inside our bodies and out overall health as well as specifically our urinary health.

Urine can undertake many colors when it exists our system. Some of the colors are normal such as yellow colored urine or white colored urine. Even if pee color is a little darker, and the pee is orange, most of the time it may mean that you are simply dehydrated. Dehydration is dangerous and you must make sure to drink more water or consume less caffeine or alcohol. Another urine color that isn't usually a sign of anything bad, but looks pretty weird is green pee color. Urine can turn green after eating many vegetables, and especially asparagus, which is known to cause weird urine colors and smells.

There are, of course, some of the more alarming colors that your urine can turn. Cloudy urine can be a symptoms of a number of metabolic issues and a sign that your kidneys are having to filter extra chemicals that make their way into your pee, making it appear cloudy. Additionally, if you see red in your pee during micturition, try to discern if it is blood. In case it is really blood, this is called Gross Hematuria which means that the blood in pee is visible with the naked eye.
