What are the factors that initiate phagocytosis?
The process of phagocytosis begins with the binding of opsonins (i.e. complement or antibody) and/or specific molecules on the pathogen surface (called pathogen-associated molecular pathogens [PAMPs]) to cell surface receptors on the phagocyte. This causes receptor clustering and triggers phagocytosis.
What is the movement of phagocytes?
Chemotaxis is the movement of phagocytes toward an increasing concentration of some attractant such as bacterial factors (bacterial proteins, capsules, LPS, peptidoglycan, teichoic acids, etc.), complement proteins (C5a), chemokines (chemotactic cytokines such as interleukin-8 secreted by various cells), fibrin split …
Which of the following defensive cell types is not phagocytic quizlet?
Which of these cells do NOT have phagocytic activity? Reason: Lymphocytes are NOT phagocytic. Eosinophils, macrophages, and neutrophils have phagocytic activity. You just studied 72 terms!
Which of the following cell types are the main phagocytic cells of the immune system?
Phagocytic cells of the immune system consist predominantly of macrophages and neutrophils. These cells represent the major cellular effectors of nonspecific host defense and inflammation.
Which of the following occurs during phagocytosis?
Phagocytosis is a process wherein a cell binds to the item it wants to engulf on the cell surface and draws the item inward while engulfing around it. The process of phagocytosis often happens when the cell is trying to destroy something, like a virus or an infected cell, and is often used by immune system cells.
Which of the following does not act as a phagocyte?
Thus, the correct answer is ‘Basophil.

Which of the following cell types does not do phagocytosis?
What occurs during phagocytosis quizlet?
Phagocytosis – the process by which particulate matter is engulfed and degraded by a cell. This is in contrast to endocytosis – a process by which soluble macromolecules are taken into a cell.
What are the 5 steps of phagocytosis?
Step 1: Activation of Phagocytic cells and Chemotaxis.

Which of the following can perform phagocytosis?
Several types of cells of the immune system perform phagocytosis, such as neutrophils, macrophages, dendritic cells, and B lymphocytes.
What is a phagocyte quizlet?
Phagocytes are cells found in the bloodstream and protect the body by ingesting and destroying foreign cells. These include, bacteria, dead or dying cells and other invading cells. They are part of the immune system.
Which is not phagocytic?
So, the correct answer is ‘Lymphocytic/Basophil’.
Which of the following is the correct order of events that occur during phagocytosis?
The correct answer is B) chemotaxis, adherence, ingestion, digestion, killing.
Which of the following cells can exhibit process of phagocytosis?
Several types of cells of the immune system perform phagocytosis, such as neutrophils, macrophages, dendritic cells, and B lymphocytes. The act of phagocytizing pathogenic or foreign particles allows cells of the immune system to know what they are fighting against.
