Verified step by step guidance

Understand the structure of the renal corpuscle, which consists of the glomerulus and Bowman's capsule. The glomerulus is a network of capillaries where blood filtration begins.

Recognize that filtration in the renal corpuscle is driven by pressure differences. The primary force is the hydrostatic pressure in the glomerular capillaries, which pushes fluid out of the blood and into the Bowman's capsule.

Consider the role of osmotic pressure, which opposes filtration. Osmotic pressure in the glomerular capillaries is due to plasma proteins that draw water back into the capillaries.

Evaluate the hydrostatic pressure in the Bowman's capsule, which also opposes filtration by pushing fluid back into the glomerular capillaries.

Conclude that the primary driving force for filtration is the hydrostatic pressure in the glomerular capillaries, as it is the main force pushing fluid out of the blood and into the Bowman's capsule, overcoming the opposing pressures.
