[{'content': "GFR will be increased if: \nSelect and explain. \nA. Increased hydrostatic pressure in Bowman's capsule, B. Decreased oncotic pressure in glomerular capillaries, C. Increased oncotic pressure in glomerular capillaries, D. Decreased hydrostatic pressure in glomerular capillaries", 'role': 'user'}, {'content': "Answer: B \nExplanation: Starling's forces acting at the glomerulus are as follows : (1) Factors oring filtration - Glomerular capillary hydrostatic pressure - If it decreases, GFR would decrease. (Option D) Bowman's capsule oncotic pressure (2) Factors opposing filtration - Plasma colloid oncotic pressure - If this pressure decreases, GFR would increase. Bowman's capsule hydrostatic pressure - (option A) If this pressure increases, GFR would decrease.", 'role': 'assistant'}]
