The glomerulus (pl.: glomeruli) is a network of small blood vessels (capillaries) known as a tuft, located at the beginning of a nephron in the kidney. Each of the two kidneys contains about one million nephrons. The tuft is structurally supported by the mesangium (the space between the blood vessels), composed of intraglomerular mesangial cells.
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. A glomerulus is enclosed in the sac. Fluids from blood in the glomerulus are collected in the ...
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
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
Each arcuate artery supplies several interlobular arteries that feed into the afferent arterioles that supply the glomeruli. Blood drains from the kidneys, ultimately into the inferior vena cava . After filtration occurs, the blood moves through a small network of small veins ( venules ) that converge into interlobular veins .
Glomerulonephrosis is a non-inflammatory disease of the kidney presenting primarily in the glomerulus (a glomerulopathy) as nephrotic syndrome.The nephron is the functional unit of the kidney and it contains the glomerulus, which acts as a filter for blood to retain proteins and blood lipids.
A further adaptation mechanism is an increase in the size of the renal glomeruli in large mammals (and, accordingly, an increase in the length of the tubules), as in elephants, in which the diameter of the glomerulus can be 2 times larger than in killer whales. [93]
Similar to other causes of nephrotic syndrome (e.g., focal segmental glomerulosclerosis or minimal change disease), membranous nephropathy is known to predispose affected individuals to develop blood clots such as pulmonary emboli. Membranous nephropathy in particular is known to increase this risk more than other causes of nephrotic syndrome ...
