Immune System - Coggle Diagram
Involves the Cytotoxic T cell which is a white cell
Third line of defense
ability to destroy infected cells, release signals to cells to make apotosis "self destruction"
do that by realising a protein called Perfonin
These cells are stimulated when the infected cell presents an antigen from the pathogen and also macrophages process the pathogen and the antigens from the pathogen are moved to the macrophage surface. and then release signals.
Involves the T helper cells and the B cellls
Help to activate white blood cells, when a cell is infectated the T cells give signals to stimulate B cells.
Take part in cell mediated and humoral response
3rd line of defence
B cells are white blood cells and have the ability to create antibodies to fight different pathogens.
In both, cell mediated and humoral cells
There are Memory Cells
Part of the 3rd line of defense
Stores memory of pathogens
This is very important, and is where also vaccines come in
Vaccines may introduce an inactivated or weakened pathogen to our bodies
They do this in order to launch an immune response
Memory cells will carry on an effective attack if the pathogen is encountered in the future
It feautres cells in our bodies that work together to protect us from a threat of pathogens
Pathogens can be
Our body has a external protection against these pathogens
Lines of defense
3 Lines of defense
1st: Non Specific: Skin and Mucous membrane
2nd: Phagocytic white blood cells: Macrophages
3rd: Lymphocytes - specific white blood cells: B and T cells
Can be specific and non-specific responses
It has a commplement system
Works to help the immune system by haveng specific or non specific responses
Its a response to an antigen
An antigen is something that our body recognizes as a non-self / may be the part of a pathogen
That adaptive response conform third line of defense
