Task: Question Answering
Input (English): Question: Indicate the correct answer regarding the forces that influence the filtration through the capillaries of the renal glomeruli (Glomerular Filtration) that takes place in the renal corpuscle: 
 Options:  <1> The hydrostatic pressure of the blood circulating in the glomerular capillaries favors filtration to the Bowman's capsule. <2> The colloid osmotic pressure due to the plasma proteins within the glomerular capillaries favors filtration towards the Bowman capsule. <3> The hydrostatic pressure of the liquid inside the Bowman's capsule favors filtration into Bowman's capsule. <4> The net gradient of the sum of these three pressures is 100 mm Hg in favor of filtration. <5> All the above are correct.
Output (English): 1
