Question

During the inflammatory response, what term describes how circulating neutrophils cells stop rolling and stick to the endothelium?

Answer 1

• Inflammation is response of body to injury.
• In this process, WBCs (Neutrophils) moves out to blood vessel and kills the pathogens.
• Cellular changes in blood vessel are divided into four steps :-
1. Margination - In this step, cells (WBCs) start moving towards margins of vessels due to change in blood flow.
2. Rolling - WBCs roll on vessel wall cells.
3. Adhesion - Receptors of WBCs interact with receptors of vessel wall cells and WBCs stop moving.
4. Diapedesis - WBCs cross the vessel and move out.

Now, in question.
• 'Adhesion' is term which describes how circulating neutrophils cells stop rolling and stick to the endothelium.
