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.
What is the name of the process where a white blood cell engulfs a pathogen?
The process by which white blood cells engulf bacteria is termed phagocytosis. In some organisms, phagocytosis is how food is absorbed.
Why do macrophages need so much energy?
The Macrophage, an amoeboid-like cell is phagocytic and engulfs foreign materials which are coated with antigens. This capture and digestiv process can deplete a lot of its energy stores. This is why the macrophage contains a lot of mitochondria to make its own ATP.
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

Does amoeba engulfs require energy?
yes
What are macrophages specialized for?
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.
