An obstruction in the afferent arteriole would reduce the flow of blood into the?
efferent arteriole]
What happens to blood pressure when the smooth muscle of an arteriole contracts?
When the radius of the smooth muscle decreases the pressure increases. So the blood pressure becomes higher
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.
Why is the blood pressure lower in lung capillaries than body capillaries?
Because if blood pressure in lung capillaries was as high as it is in body capillaries, the hydrostatic pressure caused by this blood pressure would force blood plasma out of the capillaries into intracellular spaces (as is done in body capillaries) or into the alveoli. This would reduce the efficiency of gas exchange.
Which system controls the rate at which you blink?
Iris muscles! The circular muscles contract to reduce the size of the pupil in bright light. Radial muscle fibres contract to widen the pupil in places of low light intensity. The contraction and relaxation of circular and radial muscle fibres in the iris are antagonistic, and an example of cerebral reflex.

How do you reduce the big muscle or fat at cnemis?
To reduce the big muscle or fat at the cnemis, raise legs at 90 degrees when tired. Also refrain from using high heels as it will cause further development of the muscle, making it look bigger.
