What is the name of the process where a white blood cell engulfs a pathogen?
Phagocytosis is the process by which a white blood cell engulfs and destroys pathogens such as bacteria or viruses. In this process, the white blood cell surrounds the pathogen with its cell membrane, forming a vesicle called a phagosome, which then fuses with lysosomes to break down the pathogen.
How is invading bacteria detroyed?
The bacteria has tiny, oddly-shaped molecules on it's surface, which are different for every type of bacteria, these are called antigens. When a special type of white blood cell, called a lymphocyte, realises an invading bacteria is in the bloodstream, it starts to make tiny connectors called antibodies. These antibodies fit the antigens on the bacteria's surface, and join many bacteria together. Once lots of bacteria have been joined together, another type of white blood cell, called a phagocyte, engulfs them, and it will usually take a few days for all the bacteria to be destroyed.
How does the body protect itself from pathogens?
There are 3 barriers of protection 1st barrier is called the physical barrier This includes: ·Skin ·Hairs ·Mucus ·Tears 2nd barrier is to heal the wound/cut as quickly as possible This includes ·Scabs The 3rd barrier is called white blood cells This includes ·The white blood cell Phagocytes ·The white blood cell Lymphocytes
Macrophage cells are specialized cells that do what?
macrophages can be considered one of the many "defenses" that work to help protect our immune system. they do have a special role. they engage in phagocytosis which is the process in which a macrophage engulfs cellular debris or dead cellular material and pathogens. the material goes into the internal part of the macrophage (vacuole) it then travel to the lysosomes where the waste is broken down and it then the reduced material is released extracellularly or intracellulary. in the case of a pathogen a macrophage will present an antigen for the particular pathogen in order for the immune system to identify it. each antigen has a specific helper T cell for each pathogen.
What is the process called when a cell surrounds a large particle with pseudopodia and then engulfs it?
Phagocytosis is the process by which a cell engulfs a large particle by extending pseudopodia around it and bringing it into the cell in a membrane-bound vesicle.

Is plasmodium a pathogen or parasite?
plasmodium in the phylum sporozoa is called a parasite b/c it surrounds and engulfs its food
The process by which a white blood cell ingests a disease causing organism?
The process by which a white blood cell ingests a disease-causing organism is called phagocytosis. The white blood cell engulfs the pathogen using its cell membrane, forming a vesicle called a phagosome. The phagosome then fuses with a lysosome to form a phagolysosome, where the pathogen is destroyed.
What engulfs invading microorganisms and dead neural tissue in the cns?
Immune cells called microglia engulf and digest invading microorganisms as well as dead neural tissue in the central nervous system (CNS). They serve as the primary immune defense within the CNS and help to maintain tissue homeostasis by removing unwanted material.
Where is the food after the amoeba engulfs it?
Hamburger

What is an everyday example of vacuole?
An everyday example of a vacuole is the food vacuole inside a white blood cell. When the cell engulfs a pathogen, it forms a food vacuole to digest and break down the pathogen. This process helps the white blood cell defend the body against infections.

A sarcodine engulfs food by?
surrounding the food with pseudopodia
What is the process in which an amoeba engulfs its prey?
metaphor sis
Will they world end?
Yes, when the sun expands and engulfs it
