Verified step by step guidance

Understand the context: Interstitial fluid is the fluid that surrounds cells in tissues. It moves between the capillaries and the surrounding tissue to maintain fluid balance and nutrient exchange.

Recall the key processes: Filtration, osmosis, active transport, and facilitated diffusion are mechanisms by which substances move across membranes. Each has distinct characteristics.

Define osmosis: Osmosis is the movement of water molecules across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration. This process is driven by osmotic pressure.

Apply the concept to the venous end of a capillary bed: At the venous end of a capillary, the osmotic pressure (due to plasma proteins like albumin) exceeds the hydrostatic pressure. This causes water to move back into the capillaries from the interstitial fluid via osmosis.

Conclude the reasoning: Since osmosis is the process responsible for the movement of interstitial fluid into the venous end of the capillary bed, it is the correct answer.
