Answer:
10 mmHg
Explanation:
Net filtration pressure may be defined as the pressure present at the end of venule capillary. This pressure is important for the proper functioning of kidney.
Net filtration pressure can be calculated by difference between glomerular blood hydrostatic pressure (55 mmHg) and the sum of capsular hydrostatic pressure (15mmHg) and blood colloid osmotic pressure (30mmHg). The calaculated net filtration pressure is 10mmHg.
Thus, the correct answer is option (b).
