Verified step by step guidance

Understand the context of inflammation: Inflammation is the body's response to injury or infection, involving various processes to protect and heal tissues.

Identify the role of white blood cells: White blood cells (leukocytes) are crucial in the immune response, moving to sites of injury or infection to combat pathogens.

Define diapedesis: Diapedesis is the process by which white blood cells move through the walls of capillaries into the surrounding tissues. This is essential for the immune response during inflammation.

Differentiate from other processes: Diapedesis is distinct from blood clotting, which involves platelets and fibrin to stop bleeding, and from vasodilation, which increases blood flow to the affected area.

Recognize the importance of diapedesis: This process allows white blood cells to reach and accumulate at sites of infection or injury, facilitating the immune response and promoting healing.
