Does dilation of the afferent arteriole decrease Glomular filtration rate?
No, dilation of the afferent arteriole typically increases glomerular filtration rate by allowing more blood flow into the glomerulus. Constriction of the afferent arteriole would decrease the glomerular filtration rate.
Dilation of the afferent arteriole decrease GFR?
Dilation of the afferent arteriole increases blood flow into the glomerulus, leading to an increase in glomerular filtration rate (GFR) due to the increased pressure on the filtration membrane. This can result in increased urine production.
Know relationships and differences between Afferent vs efferent arterioles?
afferent glomerular arteriole a branch of an interlobular artery that goes to a renal glomerulus.efferent glomerular arteriole one arising from a renal glomerulus, breaking up into capillaries to supply renal tubules.Remember because they are arterioles NOT venules they they both carry blood away from the heart.
How is blood pressure affected when you increase dilation?
Blood pressure drops as dilation increases. This occurs because of decrease resistance.
Sympathetic nervous system stimulation causes what?
with stimulation of the sympathetic nervous system there will be a. constriction of the pupils b. dilation of the coronary arteries c. constriction of selected blood vessels d. profuse sweating

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.

What is ateriole dilation?
Arteriole dilation is an increase in the diameter of a small artery.
What is vasomotor instability?
Relating to, causing, or regulating constriction or dilation of blood vessels. Source: Answers.com
Blood pressure is affected by constriction and dilation of?
Blood vessels. Constriction of blood vessels increases blood pressure by reducing the space for blood flow, while dilation of blood vessels decreases blood pressure by increasing the space for blood flow.
How high blood pressure built up in the glomerulus?
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.
What causes sympathetic division stimulation?
with stimulation of the sympathetic nervous system there will be a. constriction of the pupils b. dilation of the coronary arteries c. constriction of selected blood vessels d. profuse sweating

Blood pressure drops as dilation increases. This occurs because of decrease resistance.
What is the medical term when the iris is moving?
Dilation of the pupil is known as mydriasis in medical terms. Miosis is the medical term for constriction of the pupil.
