Explanation:
Detailed explanation-1: -These chemicals cause blood vessels to leak fluid into the tissues, causing swelling. This helps isolate the foreign substance from further contact with body tissues. The chemicals also attract white blood cells called phagocytes that “eat” germs and dead or damaged cells. This process is called phagocytosis.
Detailed explanation-2: -Neutrophils: These white blood cells are among the first to travel to a site of infection. They can ingest the invading microorganisms while also releasing special proteins called enzymes that help destroy them.
