Know the fundamental role of your excretory system in the body

The human body is a perfectly designed machine which, with the passage of time, has evolved to become what it is today.

A lot of systems made up of many organs are conjugated within each organism; These are responsible for fulfilling functions, some more elaborate than others, but all vital for the human being.

If any of these enter into ‘gaps’ or deficiencies, the body can present problems of a considerable nature.

Excretory system

One of the most relevant in the human body is the excretory system, responsible for eliminating all kinds of substances and unnecessary waste of the body.

Its main objective is to preserve the health of the body in general. And, in case of not evacuating this waste, infections will multiply rapidly.

Organs of the excretory system

Within the excretory apparatus there are different organs that combine their functions to help the elimination of toxins and purification of the body; therefore they are part of said excretory set.

These are the primordial organs of this system:


1. Eccrine glands

In general terms, the sweat glands are the best known of the excretory system; However, there is another equally important type with similar functions.

This is the eccrine, responsible for eliminating excess water lodged in the body. These are found along the body, although those of the palms of the hands, the soles of the feet and the forehead stand out.

  • When said glands eliminate water, they contribute to the regulation of temperature.

2. Large intestine

Although this body is not typical of the excretory system, it does fulfill vital functions for it , taking into account its objective of waste collection.

In this the solid waste coming from the body is stored, separating it from useful water for the organism.

Once fragmented, the intestine leads them through their ducts until they are definitively expelled.

3. The kidneys

They are perhaps the pair of insignia organs of the excretory system. In fact, many people often believe that these are the main body, with respect to this function.

However, despite playing a key role, the excretion of substances harmful to the body can not be carried out if the other organs do not work properly.

First, each kidney is responsible for filtering the blood to separate the unhelpful waste from the blood and water, which is reabsorbed by the body.

Salt is one of the most isolated ingredients in this organ. It travels to the bladder and is eliminated through urine.

4. The liver

The liver works together with other organs to purify the body effectively.

  • For example, it takes the ammonia and transforms it into urea, which is expelled later through the urine.
  • In this also the processes are carried out to later decompose the fats and polluting residues for the body .

5. The skin

Earlier we talked about the eccrine glands, which are distributed throughout the body. This is the reason why the skin becomes relevant in excretory processes.

The sweat glands are also found on the skin. Therefore, it helps to eliminate sweat, composed of salt and water .

Thus, it keeps the body fresh, regulates temperature and protects internal organs.

6. The lungs

In spite of having a main objective different from that of the excretory system (absorbing oxygen for the organism), the lungs do fulfill a function related to excretion.

Inside these is carried out the exchange of blood, between oxygenated and deoxygenated.

In that sense, the body is left with clean blood and the lungs expel, through the air, carbon dioxide.

Diseases belonging to the excretory system

When the mentioned organs present irregularities in their functioning, the most common is the appearance of various diseases.

However, the main ailments of this system are the following:

  • Kidney stones: They occur when substances and protein particles are stored in the kidneys.
  • Cystitis: This is the inflammation of the bladder, related to the expulsion of substances thanks to urine.
  • Urethritis: The urethra is part of the excretory system, because urine circulates through it. Its inflammation is one of the main diseases of this.
