Organ (anatomy)

In anatomy , an organ is the set of tissues that perform some specific function. An organ is made up of different kinds of tissues such as muscles or membranes .

Organs represent the level of biological organization above the “tissue” and below the “system.”

Organs generally function within systems or apparatuses, that is, intertwined with other organs to perform a function. Thus, in the digestive system we have the liver , stomach or intestine , each of which corresponds to a function .


Eyes , skin, and heart are considered organs , but not all are of equal importance. The term vital organs is used to refer to those without which one cannot live, such as the lungs or the pancreas .


They are the main organs of the respiratory system . In them, the carbon dioxide- laden blood is cleaned and charged with oxygen . The passage of oxygen to the blood occurs through the alveoli, which are the ramifications of the bronchi inside the lungs.

The introduction of oxygen into the lungs and the expulsion of carbon dioxide occurs through breathing movements of inspiration and expiration.

The lungs are not muscles like the heart , that is why the breathing movements are not performed by them but by a muscle called the diaphragm located below the lungs.


They are two organs of the body located in the lower back or posterior area of ​​the abdomen . Its main function is to filter the blood and help to eliminate the waste present in it.

There are filters in the kidneys that are called nephrons. When the blood has been filtered, its circulation continues. Meanwhile, the waste filtered by the kidneys will later be expelled through the urine .

The ureters are responsible for conducting the fluid with waste from the kidney to the bladder . When it fills up with fluid, the urine is expelled through the urethra .


It is one of the main vital organs of the human body. It is located on the right side of the abdomen. Among its functions, the transformation of harmful substances for the body into other harmless ones stands out. The liver also performs other functions such as the manufacture of bile, which is essential for digestion . It is also responsible for transforming part of the food into carbohydrates and is capable of manufacturing proteins .


It is an organ of the digestive system located in the right part of the abdomen. It is a gland that secretes substances called enzymes, necessary for the performance of digestive function . Another major function of the pancreas as a gland is the production of hormones such as insulin. This serves to maintain adequate blood sugar levels. Diabetes may be due to a deficit in insulin production, which is handled by the pancreas .


It is part of the lymphatic system . It is located in the upper left part of the abdomen. It is not a vital organ because it is possible to live without it, although the body would become more fragile in the face of infections. Among its functions is to filter blood and remove defective red blood cells from it . It is also in charge of producing antibodies that help defend against infections.
