What is in the interstitium?

The interstitium is composed mainly of collagen types I, III, and V, elastin, and glycosaminoglycans (mucopolysaccharides, such as hyaluronate and proteoglycans) which are mechanically entangled and cross-linked to form a gel-like reticulum reminiscent of a brush-pile in terms of its three-dimensional organization ( …

What is the difference between parenchyma and interstitium?

The parenchymal or alveolar interstitium provides delicate fibers to support the intralobular air-exchanging portion of the lung. The space between the visceral pleura and the lung parenchyma is termed the peripheral (or subpleural) interstitium and sends strong supporting fibers to the parenchyma.

What are the 2 fluid compartments differentiate them?

The two main fluid compartments are the intracellular and extracellular compartments. The intracellular compartment is the space within the organism’s cells; it is separated from the extracellular compartment by cell membranes.

Is interstitial fluid extracellular or intracellular?

Extracellular fluid is further divided into three types: interstitial fluid, intravascular fluid, and transcellular fluid. Therefore, the fluid that is found within cells is called intracellular fluid. On the other hand, the fluid between blood vessels and cells is called interstitial fluid.

Is blood interstitial fluid?

Interstitial Fluid, henceforth denoted as ISF, is a bodily fluid naturally produced via trans-capillary blood exchange which surrounds cells and tissues. Biologically, ISF exists as a carrier of both nutrients and waste, causing it to hold high concentrations of biomarkers typically found in the blood.

What is the interstitium of the lungs?

The interstitium is a lace-like network of tissue that goes throughout both lungs. It supports your lungs’ tiny air sacs, called alveoli. Normally, the interstitium is so thin that it doesn’t show up on X-rays or CT scans.

What is the interstitium of the kidney?

The renal interstitium is defined as the intertubular, extraglomerular, extravascular space of the kidney. It is bounded on all sides by tubular and vascular basement membranes and is filled with cells, extracellular matrix, and interstitial fluid (1).
