no, it would increase GFR constriction would decrease GFR
Yea....about that... AIDS
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.
Yes, contractions are a function of specialized epithelial tissues such as smooth muscle cells. These cells have the ability to contract and relax, allowing movement and functions such as peristalsis in the digestive system or constriction and dilation of blood vessels.

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.
Arteriole dilation is an increase in the diameter of a small artery.
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.

Dilation of the pupil is known as mydriasis in medical terms. Miosis is the medical term for constriction of the pupil.
Serotonin has an constrictive effect on the blood vessels in the brain. It's role in the rest of the body can cause both dilation or constriction.
