The glomerulus and its surrounding Bowman's capsule constitute a renal corpuscle, the basic filtration unit of the kidney. [2] The rate at which blood is filtered through all of the glomeruli, and thus the measure of the overall kidney function, is the glomerular filtration rate .
The renal corpuscle is composed of two structures, the glomerulus and the Bowman's capsule. [3] The glomerulus is a small tuft of capillaries containing two cell types. Endothelial cells, which have large fenestrae, are not covered by diaphragms. Mesangial cells are modified smooth muscle cells that lie between the capillaries.
In zoology, the trilobite Fenestraspis possessed extensive fenestrae in the posterior part of the body. [8] In the Paleognathae, there is an ilio–ischiatic fenestra. Fenestrae are also used to distinguish the three types of amniote: The ancestor of the amniotes is a primitive lizard, Hylonomus. From this reptile, three groups of amniotes ...
The glomerular basement membrane of the kidney is the basal lamina layer of the glomerulus.The glomerular endothelial cells, the glomerular basement membrane, and the filtration slits between the podocytes perform the filtration function of the glomerulus, separating the blood in the capillaries from the filtrate that forms in Bowman's capsule.

The glomerulus is the network, known as a tuft, of filtering capillaries located at the vascular pole of the renal corpuscle in Bowman's capsule. Each glomerulus receives its blood supply from an afferent arteriole of the renal circulation .
The renal glomerulus may double or triple in diameter. These compensatory changes are similar to the changes in nephrons that occur after birth as the kidney grows. [ 196 ] Resection of kidney tissue also does not cause kidney regeneration, [ 197 ] however, compensatory changes can also occur after kidney damage if it leads to a significant ...
Glomerulus (/ ɡ l ə ˈ m ɛr (j) əl ə s, ɡ l oʊ-/; pl.: glomeruli) is a common term used in anatomy to describe globular structures of entwined vessels, fibers, or neurons. Glomerulus is the diminutive of the Latin glomus, meaning "ball of yarn". Glomerulus may refer to: Glomerulus (kidney), the filtering unit of the kidney
The most proximal part of the nephron is glomerulus, which is located in the cortex. [28] The nephrons of the mammalian kidneys have loops of Henle , which are the most efficient way to reabsorb water and produce concentrated urine to conserve water in the body. [ 12 ]
