From the TPRH Science Workbook:

When pathogens invade tissues, they trigger an inflammatory response which dilates blood vessels. This leads to:

D. an increase in fluids entering the tissues

Can anyone explain this to me? I thought dilating blood vessel = decreasing blood pressure = lower hydrostatic pressure to let fluids enter the tissues

Thanks

Vasodilation = more fluid can "fit" inside the vessel at any given time. More fluid available = more fluid can diffuse into the tissue.
