Which of the following occurs when the permeability of blood vessels jncreases during inflammation? migration of white blood cells to the site of injury increased blood flow to the area redness and heat at the injury site removal of foreign material from the blood

When the permeability of blood vessels increases during inflammation, the following occurs: 1. **Migration of white blood cells to the site of injury**: Increased permeability allows white blood cells to exit the bloodstream and migrate to the site of injury or infection. 2. **Increased blood flow to the area**: While increased permeability can be associated with increased blood flow, the primary effect of increased permeability is the movement of fluids and cells out of the blood vessels. 3. **Redness and heat at the injury site**: Increased blood flow (due to vasodilation) and the accumulation of fluid contribute to redness and heat at the injury site. 4. **Removal of foreign material from the blood**: This is a secondary effect that can occur as white blood cells migrate and function to clear pathogens and debris. In summary, the most direct consequence of increased permeability during inflammation is the **migration of white blood cells to the site of injury**.
