What is phagocytosis Class 9?
Phagocytosis refers to the process by which certain living cells called phagocytes engulf other cells, particles and even pathogens.
Phagocytosis process occurs when the cell tries to destroy foreign particles or pathogens such as bacteria or an infected cell by engulfing it in lytic enzymes..
What are the 3 types of phagocytes?
There are three main groups of phagocytes: monocytes and macrophages, granulocytes, and dendritic cells, all of which have a slightly different function in the body.
What does the term phagocyte mean?
phagocyte. [ făg′ə-sīt′ ] Any of various organisms or specialized cells that engulf and ingest other cells or particles. In vertebrate animals, phagocytes are white blood cells that break down bacteria and other microorganisms, foreign particles, and cellular debris.
Can phagocytes kill viruses?
Another function of phagocytosis in the immune system is to ingest and destroy pathogens (like viruses and bacteria) and infected cells. By destroying the infected cells, the immune system limits how quickly the infection can spread and multiply.
How do phagocytes kill bacteria?
In general, phagocytes aim to destroy pathogens by engulfing them and subjecting them to a battery of toxic chemicals inside a phagolysosome. If a phagocyte fails to engulf its target, these toxic agents can be released into the environment (an action referred to as “frustrated phagocytosis”).
How do phagocytes fight infection?
Phagocytes surround any pathogens in the blood and engulf them. They are attracted to pathogens and bind to them. The phagocytes membrane surrounds the pathogen and enzymes found inside the cell break down the pathogen in order to destroy it.
What are natural killer cells?
Natural Killer (NK) Cells are lymphocytes in the same family as T and B cells, coming from a common progenitor. However, as cells of the innate immune system, NK cells are classified as group I Innate Lymphocytes (ILCs) and respond quickly to a wide variety of pathological challenges.

What are the two types of phagocytes?
Types of phagocytes In humans, and in vertebrates generally, the most-effective phagocytic cells are two kinds of white blood cells: the macrophages (large phagocytic cells) and the neutrophils (a type of granulocyte).
What is phagocytosis example?
Examples of Phagocytosis White blood cells are known as “professional” phagocytes because their role in the body is to find and engulf invading bacteria. … Ciliates are another type of organisms that use phagocytosis to eat. Ciliates are protozoans that are found in water, and they eat bacteria and algae.
What is the best definition of phagocytosis?
Phagocytosis: The process by which a cell engulfs particles such as bacteria, other microorganisms, aged red blood cells, foreign matter, etc. The principal phagocytes include the neutrophils and monocytes (types of white blood cells). The prefix “phago-” comes from the Greek “phago” meaning “to eat.”
Is a phagocytes a white blood cell?
Phagocyte, type of cell that has the ability to ingest, and sometimes digest, foreign particles, such as bacteria, carbon, dust, or dye. … In the blood, two types of white blood cells, neutrophilic leukocytes (microphages) and monocytes (macrophages), are phagocytic.
