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).

What supplies the kidney with blood?

your body has renal arteries which bring blood to your kidneys. those arteries then break up into a bunch of capillaries which then force the blood through the glomerolus which takes out mainly water, urea, ammonia, and salt from your blood. Then the filtrate (what the glomerolus removes) runs through the nephrons to filter the blood. and some things like water and a little salt are reabsorbed and carried away by your renal veins.


Where in the kidneys does the filtering takes place?

Within the nephron (the functional unit of the kidneys), filtration occurs in the glomerolus. The filtered fluid is called filtrate. Reabsorption of filtrate occurs in a few places within the nephron, however, the majority of reabsorption takes place in the proximal convoluted tube. It is important to mention that additional reabsorption occurs in the Loop of Henle, distal convoluted tube, and the collecting ducts as well. Again, however, MOST reabsorption of filtrate from the glomerolus takes place in the proximal convoluted tube of the nephron.
