The Interstitium. The interstitial space that lies between blood vessels and cells provides the fluid and structural environment surrounding those cells. Under most conditions in most tissues, fluid from the vascular space continually filters from the microvessels into the interstitial space and is not reabsorbed (1).
Where is interstitial fluid found in the body?
interstitial spaces
The interstitial fluid is found in the interstitial spaces, also known as the tissue spaces. On average, a person has about 11 liters (2.4 imperial gallons or about 2.9 U.S. gal) of interstitial fluid that provide the cells of the body with nutrients and a means of waste removal.
What is interstitial place?
Definition of interstitial area
: a transitional urban area (as between an industrial and residential district) that may be characterized by a degree of cultural isolation and consequent incidence of crime and delinquency.
What are the interstitial tissues?
Interstitial tissue is composed of cells, water and electrolytes, ground substance, and fibrillary elements (Figure 2-1).The ground substances and supporting fibers of interstitial tissue are produced by specialized connective tissue cells derived from the mesoderm (mesenchymal cells), mainly fibroblasts.
Is interstitial fluid part of blood?
The rest of the body fluid is located outside of the human cells and is referred to as extracellular fluid (ECF). The ECF components are: interstitial fluid (fluid between the cells), lymph (fluid that circulates throughout the lymphatic system), and blood.
Does blood contain interstitial fluid?
Fluid found in the spaces around cells. It comes from substances that leak out of blood capillaries (the smallest type of blood vessel). It helps bring oxygen and nutrients to cells and to remove waste products from them.
What does the word interstitial mean in medical terms?
Medical Definition of interstitial
1 : situated within but not restricted to or characteristic of a particular organ or tissue —used especially of fibrous tissue. 2 : affecting the interstitial tissues of an organ or part interstitial hepatitis.
What is the interstitial space in the lungs?
The interstitial space consists of the walls of the air sacs of the lungs (alveoli) and the spaces around blood vessels and small airways.
What is another name for interstitial?
Interstitial synonyms

What does interstitial mean in biology?
1. Relating to, occurring in, or affecting interstices. 2. Anatomy Relating to or situated in the small, narrow spaces between tissues or parts of an organ: interstitial cells; interstitial fluid.
What is interstitial space biology?
The interstitial space is involved in fluid balance in the body, transport of metabolites and signaling molecules, and determination of the mechanical properties of a tissue, and it is curious that even in tissues where the cells are very tightly packed, this space is maintained.
What is the difference between interstitial fluid and lymph?
As the interstitial fluid begins to accumulate, it is picked up and removed by tiny lymphatic vessels and returned to the blood. As soon as the interstitial fluid enters the lymph capillaries, it is called lymph. Returning the fluid to the blood prevents edema and helps to maintain normal blood volume and pressure.
What is interstitial space in anatomy and physiology?
Interstitium. Anatomical terminology. The interstitium is a contiguous fluid-filled space existing between a structural barrier, such as a cell membrane or the skin, and internal structures, such as organs, including muscles and the circulatory system.
What does interstitial fluid carry?
Interstitial fluid acts as a kind of fuelling station in terms of nutrients for our cells. Interstitial fluid contains glucose, salt, fatty acids and minerals such as calcium, magnesium and potassium.
What is the difference between blood and interstitial fluid?
The key difference between plasma and interstitial fluid is that the plasma lies within the blood vessels and it is the liquid portion of the blood while the interstitial fluid lies between the cells of the tissues. Another difference between plasma and interstitial fluid is the protein concentration.
How interstitial fluid is removed from tissues?
It is the site of many immune system functions as well as its own functions. It is responsible for the removal of interstitial fluid from tissues into lymph fluid, which is filtered and brought back into the bloodstream through the subclavian veins near the heart.
What happens when interstitial fluid accumulates?
Excessive accumulation of interstitial fluid is generally viewed as detrimental to tissue function because edema formation increases the diffusion distance for oxygen and other nutrients, which may compromise cellular metabolism in the swollen tissue.
What is the root of interstitial?
The Latin root is interstitium, which literally means “space between.”
What is basal interstitial pneumonia?
Nonspecific interstitial pneumonia (NSIP) is a rare disorder that affects the tissue that surrounds and separates the tiny air sacs of the lungs. These air sacs, called the alveoli, are where the exchange of oxygen and carbon dioxide takes place between the lungs and the bloodstream.
What is interstitial space in chemistry?
(Chemistry) chem an atom or ion situated in the interstices of a crystal lattice.
Does Covid 19 cause interstitial lung disease?
Residual pulmonary disease is sometimes referred to as “post-COVID interstitial lung disease” (ILD). In this issue of Radiology, Han and Fan et al (1) report on a prospective cohort of 114 patients with severe COVID-19 pneumonia undergoing CT during hospital admission and 6 months later.
