Here are the essential concepts you must grasp in order to answer the question correctly.
Diapedesis
Diapedesis is the process by which white blood cells move out of the bloodstream and into tissues. This occurs during an immune response, allowing immune cells to reach sites of infection or injury. It is a crucial step in the inflammatory response, enabling the body to combat pathogens effectively.

Phagocytosis
Phagocytosis is the process by which certain cells, such as macrophages and neutrophils, engulf and digest pathogens or debris. This involves the formation of a phagosome, which is a vesicle that contains the ingested material. The phagosome then fuses with a lysosome to form a phagolysosome, where the material is broken down.

Phagolysosome Formation
The formation of a phagolysosome is a critical step in the immune response, occurring after a phagosome engulfs a pathogen. This vesicle then merges with a lysosome, which contains digestive enzymes, allowing for the breakdown of the engulfed material. This process is essential for the elimination of pathogens and the resolution of infection.
