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.
Diagram of the circulation related to a single glomerulus, associated tubule, and collecting system The renal corpuscle in the cortex (outer layer) of the kidney. At the top, the renal corpuscle containing the glomerulus. The filtered blood exits into the renal tubule as filtrate, at right. At left, blood flows from the afferent arteriole (red ...
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).
In the physiology of the kidney, tubuloglomerular feedback (TGF) is a feedback system inside the kidneys.Within each nephron, information from the renal tubules (a downstream area of the tubular fluid) is signaled to the glomerulus (an upstream area).
The renal corpuscle consists of the glomerulus, and the glomerular capsule or Bowman's capsule. [4]: 1027 The renal corpuscle has two poles: a vascular pole and a tubular pole. [5]: 397 The arterioles from the renal circulation enter and leave the glomerulus at the vascular pole. The glomerular filtrate leaves the Bowman's capsule at the renal ...
A. The endothelial cells of the glomerulus; 1. pore (fenestra). B. Glomerular basement membrane: 1. lamina rara interna 2. lamina densa 3. lamina rara externa C. Podocytes: 1. enzymatic and structural protein 2. filtration slit 3. diaphragma. Podocytes have primary processes called trabeculae, which wrap around the glomerular capillaries. [2]
There are five known functions of intraglomerular mesangial cells: structural support of glomerular capillaries, regulation of the glomerular filtration rate, mesangial matrix formation, phagocytosis, and monitoring of capillary lumen glucose concentration [citation needed].
Glomerulosclerosis is the hardening of the glomeruli in the kidney.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.
