Filtration rate through kidneys is dependent on the filtration pressure. This in turn depends on the following three factors:
l. Glomerular blood hydrostatic pressure
II. Capsular hydrostatic pressure
III. Blood colloid osmotic pressure
The net filtration pressure will be:
(a) I+ II+ III
(b) I - ( II + III)
(c) (I+III)-II
(d) II - (I + III)
