As the afferent arteriole dilates it exposes the glomerulus to an increased blood pressure, closer and closer to that of the full systemic blood pressure. This increases GFR and Glomerular pressure.

reducing afferent arteriole radius decreases filtration rate
reducing afferent arteriole radius decreases filtration rate
Decreasing the diameter of the efferent arteriole would increase the hydrostatic pressure inside the glomerulus and effectively increase the glomerular filtration rate. If you increase the diameter of the afferent arteriole you would achieve the same effect.
increase afferent radius or decrease efferent radius depending on the degree of change in blood pressure
Efferent means going away from and afferent is going toward. The afferent arteriole of the kidney carrys blood toward the glomerulus, whereas the efferent arteriole carrys blood away from the glomerulus.
In the presence of renal artery stenosis, the resistance in the afferent arteriole is increased. As compensation, Angiotensin II acts to constrict the efferent arteriole in order to achieve adequate profusion of the glomerulus. ACE inhibitors block the conversion of angiotensin I into angiotensin II. Without its vasoconstrictive effect, the efferent arteriole becomes dilated. This leads to a drop in GFR and may lead to renal failure.

As the Glomerular Hydrostatic Pressure (GHP) goes up, the Filtration rate goes up.

· Afferent and efferent divisions are:o Sensory (afferent) Division§ Somatic afferent nerves - carry impulses from skin, skeletal muscles, and joints to the CNS§ Visceral afferent nerves - transmit impulses from visceral organs to the CNSo Motor (efferent) Division§ Transmits impulses from the CNS to effector organs, muscles and glands, to effect (bring about) a motor responseAfferent nerves are the one that carry the information from periphery to central nervous system for further processing. While efferent nerves carry the processed information from central nervous system towards the periphery for action.
They can be both. Afferent axons carry (sensory) information toward the central nervous system; efferent axons carry (motor command) information away from the central nervous system towards the muscles and glands. Think "affect" vs. "effect" or "arrive" vs. "exit".
Afferent refers to pathways leading to the cortex (ie, sensory). Efferent are pathways leading away (ie, motor). You are *affected* by a situation, you *effect* change on someone else.
