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.

Define glomerular filtration rate Name and describe the pressures which are effective at the glomerulus under normal conditions and result in glomerular 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.
What is the fiber type in the dorsal root?
efferent (motor) I'm guessing it's choice B in your packet?
What is efferent nerves?
efferent signals are those sent out from your CNS instructing some part of your body to act a certain way.
What is efferent stance?
An efferent stance is when someone read to remember information. Teacher sometimes gives students assignment to read and remember specific information from the story. Forcing students to remember something is an efferent stance.
Contraction of the smooth muscle in arterioles would decrease blood pressure?
No it would increase BP, as contraction of the smooth muscle in the arterioles will make the lumen (holes) of the arterioles smaller, restricting blood flow.
Where do the afferent and efferent arterioles come in contact?
Juxtaglomerular apparatus
What vascular structure is found between the afferent and efferent arterioles?
peritubular capillaries
What Blood vessel located between afferent and efferent arterioles?
Glomerulus capillary
Why is the afferent arteriole larger than than the efferent arteriole?
Lot of fluid is filtered out in the glomeruli. Almost 180 litres of fluid per day is filtered in glomeruli. So to maintain the blood pressure in afferent arterioles, you need to have efferent arterioles with less diameter.
What condition would lead to an increase in the amount of fluid entering the bowmans capsule?
constriction of the efferent arterioles
What are the horizontal vessels of the peritubular capillaries?
Blood leaves the glomerular capillaries via a second set of arterioles, the efferent arterioles, which deliver blood to the peritubular capillaries.
Structure and function of arterioles?
The function of arterioles is to draw blood away from the brain and into harry bush's penis.
What is the Blood supply that directly receives substances from the tubular cells in urinary system?
You have portal system of blood circulation in case of kidney tubules. In portal system, you have afferent arterioles, divided to form primary capillaries and capillaries reunite to form efferent arterioles. The efferent arterioles again divide to form the secondary capillaries. So you have secondary capillaries, there in urinary system, to receive the substances, directly from tubular cells.
Cluster of tiny blood vessels in a nephron?
There's the afferent arteriole which goes to the glomerulus and the efferent arterioles which comes out of the glomerulus. These arterioles then branch out surrounding the nephron, these are called peritubular capillaries and they allow for selective reabsorption of substances as well as secretion.
What is function of arterioles?

Trace blood supply through the kidney?
***CORRECT ANSWER***Renal Arteries--> Segmental Arteries--> Lobar Arteries--> Interlobar Arteries--> Arcuate Arteries--> Cortical Radiate Arteries--> Afferent Arterioles--> Glomeruli--> Efferent Arterioles--> Peritubular Capillaries--> Cortical Radiate Veins--> Arcuate Veins--> Interlobar Veins--> Renal Vein.
What are the tuft of capillaries located between the afferent and efferent arterioles called?
The renal glomerulus is a small convoluted mass of capillaries, a network of vascular tufts, encased in the malpighian or Bowman's capsule.
