April 19: World Liver Day

The World Liver Day (WLD) is observed every year on April 19 to build awareness and understanding importance of liver in human body and how liver ailments can be treated. The 2018 theme for WLD is ‘Riding New Waves in Liver Diagnosis, Staging & Treatment’. As per World Health Organisation (WHO), liver diseases are 10th most common cause of death in India.

Liver

Liver is unique organ in human body and has special capacity of regeneration. It is the second largest organ and is key player in our body’s digestive system. Everything we consume passes through the liver. It fights infections, removes toxins, controls cholesterol, regulates blood sugar, make proteins and releases bile to help digestion. It has been seen that even 75% of liver can be safely removed without any untoward consequences because of its capacity of regeneration. Hence, to take care of the liver, one needs to adopt a healthy lifestyle and have a balanced diet of proteins, grains, dairy products, fruits, vegetables, and fats.

Interstitium: Scientists discover new organ in human body

Scientists have discovered new organ in human body and have named it as ‘interstitium’. It will be the 80th organ in the human body. It might be might be also the biggest organ in human body

It was discovered while doctors were investigating patient’s bile duct, searching for signs of cancer. They had noticed cavities of this organ that did not match any previously known human anatomy.

The discovery of interstitium will help to explain how cancer spreads in body and pave way for new ways to detect and treat the disease.

Interstitium

The new organ is network of interconnected, fluid-filled spaces all over the body. It is found everywhere in human bodies, acting as shock absorber in all places where tissues are moved or subjected to force. It is made up of both flexible (elastin) and strong (collagen) connective tissue proteins, with interstitial fluid moving throughout. It lies beneath top layer of skin, but is also in tissue layers lining gut, lungs, blood vessels, and muscles. The organ acts like shock absorber in all places where tissues are moved or subjected to force to protect them from damage.

Functions: The new organ’s interstitial spaces are organized by collagen mesh which allows it to shrink, expand making it as shock absorbers. It also acts as fluid ‘highway’ i.e. thoroughfares to transport critical fluids within organs and around body. It also plays important role in carrying lymph, a fluid that supports immunity and also travels through lymphatic vessels.
