Bulk flow in capillaries often refer to the mechanical forces which push substances in and out of capillaries. These forces are namely pressure, and in this case, blood pressure vs. pressure from surrounding cells. If there is a large amount of pressure from the capillaries from the blood, bulk flow can occur as a result of blood pressure pushing substances from the blood into the tissue outside of the capillaries. Likewise, if pressure from fluids outside the capillaries is high, it will push substances mechanically into the capillaries.
