Filtration
Glomerular Filtration - a passive process in which fluid passes from the blood into the glomerular capsule (part of the renal tubule) Once in the capsule the fluid is called filtrate and is essentially blood plasma without proteins
The glomerulus is surrounded in the kidneys by a structure called 'the Bowman's capsule'. This is where the various substances from the blood pass into - a process called filtration.
it occurs in the glomerulare (Bowman's) capsule.
Glomerular filtration is part of the process in the formation of urine. After the process of glomerular filtration is carried out, most of the fluid goes into the glomerular capsule and then into the renal corpuscle. Some of the fluid is reabsorbed by the body.

Filtration
In the kidney, a tubular structure called the nephron filters blood to form urine. At the beginning of the nephron, the glomerulus /ɡlɒˈmɛrələs/ is a network (tuft) of capillariesthat performs the first step of filtering blood.The glomerulus is surrounded by Bowman's capsule. The blood is filtered through the capillaries of the glomerulus into the Bowman's capsule. The Bowman's capsule empties the filtrate into a tubule that is also part of the nephron.A glomerulus receives its blood supply from an afferent arteriole of the renal circulation. Unlike most other capillary beds, the glomerulus drains into an efferent arteriole rather than a venule. The resistance of these arterioles results in high pressure within the glomerulus, aiding the process of ultrafiltration, where fluids and soluble materials in the blood are forced out of the capillaries and into Bowman's capsule.A glomerulus and its surrounding Bowman's capsule constitute a renal corpuscle, the basic filtration unit of the kidney. The rate at which blood is filtered through all of the glomeruli, and thus the measure of the overall renal function, is the glomerular filtration rate (GFR).
Bowmans capsule is part of the functioanl unit of the kidney called the nephron. The kidney job in the body is to filter blood and remove wastes via the urine. At the very start of each nephron is a very smalle blood network called the glomerulus. The diameter pf the vessel leaving the glomerulus (the efferent vessel) is smaller than that coming to the glomerulus (the afferent vessel) and so a large pressure occurs. This helps push the wastes as well as some nutrients and a lot of water out of the glomerulus. To stop if all just floating of into the body a a structue surround the glomerulus and takes up all the thing the glomerulus lets out. This is the glomerulus and it passes what it gets on through the vessels of the nephron where much is reabsorbed and the rest is excreted as urine.
Blood is filtered through the capillaries of the glomerulus into the Bowman's capsule. The Bowman's capsule empties the filtrate into a tubule that is also part of the nephron. The function of the glomerulus is to filter the resultant fluid that will become urine.
in the process of glomerular filtration all compounds such as amino acids,sugar,glucose and water are seprated from the blood.the pure blood is remaining.that's why it is called ultra filtration
Glomerular filtration is a passive process in which hydrostatic pressure forces fluids and solutes through a membraneThe glomerular filtration rate (GFR) is directly proportional to the net filtration pressure and is about 125 ml/min (180 L/day).The glomeruli function as filters. High glomerular blood pressure (55 mm Hg) occurs because the glomeruli are fed and drained by arterioles, and the afferent arterioles are larger in diameter than the efferent arterioles.
