What gives organs their functions


An organ is a part of the body of a living being, including humans. There are a number of organs in our body and they all have specific tasks. For example, the heart pumps blood through the veins. Another breathes so that we don't suffocate: this is the lungs, in fish it is the gills.

Other organs in the body digest our food. These are the stomach and the intestines. There is also the liver, spleen, kidneys, thyroid, brain, and many others. Muscles and bones are also organs. The largest human organ is the skin.

What kind of organs are there?

The liver is an important organ because it aids digestion and filters toxic substances from the blood.

All organs together make up an organism. Some organs exist only once in the body, others twice. They are called "paired organs". These include, for example, the lungs with their two lungs and the kidneys. Since there is only one heart and only one liver in a body, these do not belong to the paired organs. There are also organs that are common in an organism, such as the bones and muscles.

Almost all organs we have are important to life. The appendix, for example, is an exception. You can operate it away, usually after a severe inflammation. You can do without one of the paired organs if, for example, one is seriously ill with cancer. For example, you can live with only one kidney or with only one lung. That is the advantage of paired organs.

Most organs cannot be done without; without them we would die. Some organs can be replaced with artificial organs when they are sick and can no longer be recovered. But that does not work with all organs. In many cases one can also exchange the sick organ of one person for the healthy one of another person or even of an animal. Those who give their organs to sick people are called organ donors. Some organs that you absolutely need yourself, such as the heart, can only be donated after you are dead.

The sense organs with which we perceive our environment are a special form of organs. This includes:

  • the nose and the sense of smell to smell,
  • the tongue and the sense of taste to taste,
  • the ears and the sense of hearing to hear,
  • the skin and the sense of touch to feel as well
  • the eyes and the sense of sight to see.

Not only humans and animals have organs, but also plants. A root, for example, is a plant organ with its own tasks, including the bark of trees or the leaves.

What else does the word organ mean?

The word organ can have completely different meanings. In a figurative sense, one speaks of an organ when one or more people are allowed to speak or act on behalf of an organization or an entire country. For example, the Federal Chancellor is also referred to as a state body because he acts for and represents the entire state.

Some companies, associations, parties or other organizations also have their own magazines that speak on behalf of the organization and disseminate news, current events or other things worth knowing about them. These journals are also called organs. Not every organization has its own body. But many have something to make themselves known and to report about themselves in public.
