The liver is the largest internal organ in our body. It has a reddish-brown color and is located in the upper right part of the abdomen, beneath the diaphragm, to the right of the stomach. The liver plays a crucial role in numerous vital processes within the body. Its importance is such that during rest, over 25% of the blood output from the heart is directed towards it. Hundreds of continuous processes occur in every cell of the liver to maintain overall bodily health and function. The majority of substances absorbed by the intestines are directed to the liver, where they are processed before being released as building blocks to the rest of the body. The liver is involved in the metabolic exchange of sugars, proteins, and fats to ensure the body's various functions have an adequate supply. Additionally, the liver is responsible for detoxifying substances that enter the bloodstream, eliminating them from the body.
The liver produces bile juices that are stored in the gallbladder, which efficiently break down fats and absorb them. Following the consumption of fatty foods, the gallbladder contracts and releases these juices into the intestines. The liver produces a multitude of proteins and enzymes that are essential for the body's various systems. These proteins include vital factors related to blood clotting, various enzymes, and the primary blood protein called albumin. All these substances are produced, packaged, and dispatched to target organs in a delicate and precise balance that even the most advanced modern factories would envy.
Given that the entire blood supply from the digestive system passes through the liver before reaching the rest of the body, the liver has a vital role in detecting bacteria and other pollutants, isolating them, and even neutralizing them. Essentially, the liver serves as the guardian of the body's threshold. Lastly, the liver also generates and releases a diverse range of hormones critical for growth, development, and our daily functions.
From all that has been mentioned above, it is evident that the liver is one of the most vital organs in the body, and any impairment to its function can lead to substantial disruptions in the body's daily operations. Various liver diseases can cause a range of issues, including affecting blood clotting, susceptibility to infections, reduced blood protein levels (leading to fluid retention and kidney and lung issues), exposure to toxins, confusion in the body's systems, and even widespread breakdown as the damage becomes more extensive.
Fortunately, the liver is a resilient organ capable of meeting the body's needs even when most of it is compromised by disease. Moreover, in most cases, the liver has an impressive ability to regenerate itself after acute injury. It is crucial to monitor any liver dysfunction during illness at a specialized, multidisciplinary center, especially in children who are more susceptible to metabolic and pathological changes in the body.
