Three-dimensional schematic of the interstitium, a fluid-filled space supported by a network of collagen. In anatomy, 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.
Extracellular fluid may be mechanically guided in this circulation by the vesicles between other structures. Collectively this forms the interstitium, which may be considered a newly identified biological structure in the body. [36] However, there is some debate over whether the interstitium is an organ. [37]
Claude Bernard, French physician who introduced the concept of homeostasis. The human body and even its individual body fluids may be conceptually divided into various fluid compartments, which, although not literally anatomic compartments, do represent a real division in terms of how portions of the body's water, solutes, and suspended elements are segregated.
Scientists said in a study published Tuesday that they may have stumbled on an unknown organ that could significantly advance our understanding of cancer.
The interstitium between the tubules contains fibroblasts, dendritic cells, macrophages and lymphocytes. Cortical interstitium also includes the endothelial cells of the lymphatic capillaries, [96] which are considered part of the interstitium due to the lack of a basement membrane. [97] Interstitial fibroblasts form the tissue skeleton of the ...

The collecting duct system of the kidney consists of a series of tubules and ducts that physically connect nephrons to a minor calyx or directly to the renal pelvis.The collecting duct participates in electrolyte and fluid balance through reabsorption and excretion, processes regulated by the hormones aldosterone and vasopressin (antidiuretic hormone).
The interstitium of the kidney increases in osmolarity outside as the loop of Henle descends from 600 mOsm/L in the outer medulla of the kidney to 1200 mOsm/L in the inner medulla. The descending portion of the loop of Henle is extremely permeable to water and is less permeable to ions, therefore water is easily reabsorbed here and solutes are ...
