What Is The Smallest Organ In The Human Body ?

An organ is a formation of the body that carries out a definite function. Organs could consist of the heart, the lungs, the eye and the ear. Depending on what way you want to view it, we can talk about the smallest internal organ or the smallest external organ. However, here we will focus on the smallest internal organ.

Many propositions have been proffered as to the smallest internal organ in the human body, and out of all these suggestions, the one that is chosen is the lymph node. The lymph node is the smallest internal organ. Although some chose the pineal gland, a small endocrine gland located in the brain with a length of 8 mm in human, as the smallest organ, many assume the lymph node serves best in this regard.

Lymph node is  a component of the lymphatic system, which has three key functions in the body that is the removal of surplus fluid, the absorption of fat and fatty acids, and lastly, the formation of white blood cells, the body’s defense force against infection. Lymph nodes can be located anywhere around the body with sizes ranging from 2 millimeters to 1-2 centimeters in length.

They are infinitesimal filters that look for disease causing microbes in our body. They enclose reticular tissue; a structural web, that embraces lymphocytes that will sense and wipe out bacteria and viruses. The lymphocytes are continually roaming in the blood stream, and as our blood stream and our lymph system are allied, the lymphocytes are regularly flowing into and away from the lymph nodes.
