What is the function of the lymphatic system?
Once in the lymph vessels, the fluid contains many other cells and substances which aid in the immune response, by allowing white blood cells to find and digest harmful bacteria and virus infected cells. Many cells also remove their metabolic wastes into the interstitial fluid, and the wastes are cleaned through the lymphatic system.
What is the fluid between cells called?
Between the cells of the body, this fluid is known collectively as interstitial fluid. If there were no mechanism to remove it, parts of the body would swell up with pressure. Luckily, the lymphatic system is a network of vessels and tissues that actively removes the tissue fluid from tissues, and returns it to the blood plasma.
What is the fluid that is forced out of the blood?
Interstitial fluid, or simply tissue fluid, is a mixture of water, ions, and small solutes that are forced out of the blood plasma by the systolic pressure created when the heart pumps. Plasma is a mixture of water and many other constituents, which carry blood cells and oxygen to various parts of the body. Interstitial fluid makes up the large ...
Why do arteries swell with pressure?
These arteries, all the way down to the smallest capillaries, swell with pressure. Because the vessels are created by a series of cells, there exist small gaps between the many cells that make up a vessel, and some water and solutes can leak out.
Where is lymph fluid located?
Lymph is in the lymph vessels, plasma in the blood vessels, and interstitial fluid between the cells. Extracellular fluid refers to all of the above, as any fluid that exists within an organism and outside of the cytoplasm.
Which system collects and redistributes interstitial fluid to the blood?
Lymphatic System – A series of vessels that collects and redistributes interstitial fluid to the blood.

How does interstitial lung disease happen?
Interstitial lung disease seems to occur when an injury to your lungs triggers an abnormal healing response. Ordinarily, your body generates just the right amount of tissue to repair damage. But in interstitial lung disease, the repair process goes awry and the tissue around the air sacs (alveoli) becomes scarred and thickened. This makes it more difficult for oxygen to pass into your bloodstream.
Why do I have tiny air sacs?
Causes. In your lungs, the main airways (bronchi) branch off into smaller and smaller passageways — the smallest, called bronchioles, lead to tiny air sacs (alveoli).

What is the new method of looking at living tissue called?
A new method of looking at it within living tissue, called probe-based confocal laser endomicroscopy, lets researchers see these spaces filled. The fact that they're connected raises the possibility that sampling the fluid in those spaces could help experts examine the spread of diseases.
What are the walls of collagen?
Experts have long thought parts of the body (like skin, veins and arteries, and the lining around muscles) contain walls of collagen, the main component of connective tissue. Instead, as the new study points out, those "walls" aren't walls at all. Instead, they're spaces filled with fluid that are simply supported by collagen.
Is interstitium an organ?
That’s why the discovery of what some scientists call a previously unrecognized organ is so fascinating. In a new study, researchers claim that interstitium -- fluid -filled spaces in tissue that are connected throughout the body -- should be considered a new “ organ” and that these spaces may play a major part in a lot of what goes on in your body.
