the pressure in glomerulus creates higher net filtration pressure resulting large amount of filtration formed.
High blood pressure is necessary in the glomerulus to ensure that there is a high concentration gradient. This makes it easier for molecules to diffuse into the nephron.
enables higher filtration
It builds up because the calibre of the efferent arteriole is less than that of the afferent arteriole. The cappilary pressure is opposed by the lower osmotic pressure or the blood and the lower filtrate hydrostatic pressure in the glomerular capsule.
The afferent arteriole in a nephron is a larger diameter then the outgoing efferent arteriole and this increase the blood pressure in the glomerulus capillaries resulting in the ultrafiltration of the blood into the Bowman's capsule.
It doesn't cause high blood pressure. However, it can increase your blood pressure.
glomerulus
When the afferent arteriole is constricted it causes blood to be unable to flow into the glomerulus, overall decreasing hydrostatic pressure and causing the bowman's capsule to decrease filtration.
Blood pressure in the glomerulus in very high. Hope this helps!!!!!!!!!! :D
glomerulus
The glomerulus.
The diameter of the afferent renal arteriole narrows progressively more and more into the glomerular capillaries, with the same blood flow, leading to an increase in pressure within the glomerulus. This is so that the high pressure can force solutes and water across into the Bowman's capsule for the renal tubules.
blood pressure
The cluster of capillaries that forms a glomerulus arises from an afferent arteriole. After passing through the glomerular capillaries, blood (minus any filtered fluid) enters an efferent arteriole whose diameter is smaller than that of the afferent vessel. This is instead of entering a venule, the usual circulatory route. The efferent arteriole resists blood flow to some extent, which backs up blood into the glomerulus, increasing pressure in the glomerular capillary.

Is increase in blood pressure in the capillaries
The glomerulus ...
If your blood pressure is too high, as in the case of someone with hypertension, the glomerulus of the nephron can burst rendering that nephron useless. Without a glomerulus, the nephron cannot achieve pressure filtration, which is one of the main functions of the kidney.
The glomerulus is a cluster of capillaries that can be found in the kidney. Each cluster is next to a Bowman's capsule, which is the "filter unit" of the nephron. Blood passes from the renal artery into the glomerulus at high pressure, allowing small substances to diffuse into the nephron, via the Bowman's capsule.
