Explanation:
Detailed explanation-1: -Phagocytosis consists of five phases: chemotaxis, adherence, ingestion, digestion, and excretion.
Detailed explanation-2: -The first phase in phagocytosis is the detection of the target particle. Detection is mediated by dedicated receptors on phagocytic cells. Receptors directly recognizing pathogen-associated molecular patterns (PAMPs) are the pattern-recognition receptors (PRRs).
Detailed explanation-3: -Step 1: Activation of Phagocytic cells and Chemotaxis. Step 2: Recognition of invading microbes. Step 3: Ingestion and formation of phagosomes. Step 4: Formation of phagolysome. Step 5: Microbial killing and formation of residual bodies. Step 6: Elimination or exocytosis. 06-Jun-2022
