What else can I help you with?
Where does the transition from an afferent arteriole to an efferent arteriole occur?
glomerulus. The afferent arteriole leads to a ball of capillaries called a glomerulus which is enclosed in a nephron structure called the glomerular capsule. Blood leaves the glomerulus by way of the efferent arteriole.
Is the afferent arteriole entering the glomerulus always thicker than the efferent arteriole leaving the glomerulus?
It always has a widre lumen so that blood is forced to diffuse and filter. This puts a little more stress on the afferent arteriole and so a slight increase in the thickness of the tunica media may be noted.
What vessel directly feeds into the glomerulus?
The afferent arteriole feeds directly into the glomerulus.
Is the glomerular filtration rate the same when the efferent arteriole is constricted and dilated?
OLD, INCORRECT ANSWER: Changes in the diameter of the efferent arteriole will either increase (dilation) or decrease (constriction) the blood flow to the glomeruli. An increased flow means a more blood getting filtered over time. NEW, CORRECT ANSWER The 'efferent' arteriole leaves the renal corpuscle. It is easy to remember which direction efferent and afferent things are going by thinking e=exit and a=arrive. If you constrict the efferent arteriole, you actually inhibit blood from leaving the glomerulus, thus increasing the outward hydrostatic pressure pushing fluid into Bowman's capsule and increasing filtration. If you dilate the efferent arteriole, then you reduce pressure in the glomerular capillaries and reduce filtration.
The efferent arteriole carries blood from the glomerulus to the?
The efferent arteriole carries blood from the glomerulus to the peritubular capillaries in the kidney. This allows for the exchange of substances between the blood and the renal tubules during urine formation.
What is the size of the arteriole?
what is the actual size of arteriole
What is the blood vessel that drains blood from the glomerulus?
Efferent arteriole takes the blood away from the glomerulus

What arteriole supplies blood to the capillaries of the glomerulus?
afferent arteriole
Which arteriole supplies blood to the capillary of the glomerulus?
The afferent arteriole supplies blood to the capillaries in the glomerulus of the kidneys. The efferent arteriole takes the blood away from the glomerulus.
Is an arteriole a small artery?
Yes, it can be easily said that an arteriole is a miniature form of an artery.
What the arteriole leads into the glomerulus?
The afferent arteriole leads into the glomerulus, which is a bundle of small blood vessels located within the Bowman's capsule in the kidney. This is where blood is filtered to form urine in the process of urine formation.
Does the efferent arteriole take blood to the nephron?
No, the efferent arteriole carries blood away from the glomerulus in the nephron. Blood entering the glomerulus via the afferent arteriole is filtered, and the efferent arteriole carries blood containing the filtered substances away for further processing in the renal tubule.
What are the distinctive features of an arteriole?
The distinctive features of an arteriole include small diameter and its branching into capillaries.
What are tiny artery?
arteriole
What structure within a capillary bed shunts blood from arteriole to venule?
Artery -> Arteriole -> Capillary -> Venule -> Vein
What is the effect of reducing afferent arteriole radius on filtration?
reducing afferent arteriole radius decreases filtration rate
