Interstitium

  • It is a new organ discovered in human body.
  • 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.
