Verified step by step guidance

1. Understand the context of inflammation: it is a biological response to harmful stimuli such as pathogens or injury, involving increased blood flow and immune activity.
2. Recall the structure and function of capillaries: these are small blood vessels where exchange of substances between blood and tissues occurs.
3. During inflammation, the permeability of capillaries increases, allowing more fluid, immune cells, and proteins to move out of the bloodstream.
4. This movement from inside the capillaries to the surrounding tissue is called 'leaving' or 'exiting' the capillaries.
5. Therefore, the correct completion of the sentence is that during inflammation, more fluid, immune cells, and proteins leave the capillaries.
