Urine – All about the topic!

Introduction

Every person produces and excretes liters of urine every day. But what exactly is the yellowish liquid? What does it consist of and what are its benefits?

What does it mean when the color of urine changes? Is it dangerous? Urine, also known as “urine”, is an excretion product of the body, produced by the two kidneys. Urine consists mainly of excess water, which our body no longer needs. It also contains various salts, urea and other substances that the body also wants to get rid of.

How is urine produced?

To produce urine, the kidney has a complex system of filters and pipes. All the blood in the body flows past the filters of the kidney. It is first roughly filtered there.

This produces about 150 to 180 liters of primary urine. However, the primary urine contains substances that are common to the body. Of course, the body does not want to lose these substances, but rather retain them.

Therefore, the important substances in the primary urine are reabsorbed in the second pass, this is also called absorption. The resorbed substances are returned to the bloodstream. What remains is secondary urine containing substances that are not common in the body, such as urea, uric acid or phosphate.

This only makes up about 1-2 liters from the original 150 to 180 liters. The secondary urine now enters the bladder via the ureters. From there, the person can consciously excrete urine while “urinating”.

Would you like to find out more about how the kidneys function and how urine is produced? If so, we recommend our page on: The function of the kidneyThe kidneys produce about 1 liter of blood per minute. This means that all a person’s blood passes through the kidneys every 5 minutes.

In the course of a day, the kidney filters collect around 150 to 180 liters of primary urine. Since the body can recover up to 99% of the urine through the subsequent tube systems, people excrete only about 1.5 liters of secondary urine per day. The kidney is a vital organ, especially since it can regulate the body’s fluid and electrolyte balance very finely and can free the body from harmful substances through the urine. Because many of the complex mechanisms from filtering the blood to excreting the final urine can malfunction, some possible disease patterns can also occur.
