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 .
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
Bowman's capsule (or the Bowman capsule, capsula glomeruli, or glomerular capsule) is a cup-like sac at the beginning of the tubular component of a nephron in the mammalian kidney that performs the first step in the filtration of blood to form urine.
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 dia
It is a general term to describe scarring of the kidneys' tiny blood vessels, the glomeruli, the functional units in the kidney that filter urea from the blood. Proteinuria (large amounts of protein in the urine) is one of the signs of glomerulosclerosis. Scarring disturbs the filtering process of the kidneys and allows protein to leak from the ...
Glomerular filtration rate (GFR) is the volume of fluid filtered from the renal (kidney) glomerular capillaries into the Bowman's capsule per unit time. [4] Central to the physiologic maintenance of GFR is the differential basal tone of the afferent (input) and efferent (output) arterioles (see diagram).
Glomerulonephritis (GN) is a term used to refer to several kidney diseases (usually affecting both kidneys). Many of the diseases are characterised by inflammation either of the glomeruli or of the small blood vessels in the kidneys, hence the name, [ 1 ] but not all diseases necessarily have an inflammatory component.
Glomerular hyperfiltration is a situation where the filtration elements in the kidneys called glomeruli produce excessive amounts of pro-urine. It can be part of a number of medical conditions particularly diabetic nephropathy (kidney damage associated with diabetes).
