Innate Immune System
This is the body's first line of defense, providing a non-specific and immediate response
Skin
This system is highly specialized and targets specific invaders based on unique parts called antigens
Adaptive immune system
These are the most common type of white blood cell, using phagocytosis to destroy pathogens
Neutrophils
When bacteria enter the lungs, these resident cells immediately start to ingest them and release chemical signals.
Macrophages
What is bone marrow
Site of immune cell formation
This system is very fast, acting within minutes to hours
Innate immum system
describes the speed of the adaptive immune system
Slower than innate
These are the key players in cell-mediated immunity and cannot bind directly to antigens.
T cells
These chemical signals attract other innate cells like neutrophils to the infection site
Cytokines
Myeloid cells are primarily associated with this part of the immune system.
innate immunity
This describes the innate immune system's memory.
Slow/no memory
After an initial exposure, this system "remembers" a pathogen, allowing for a much faster and stronger response upon re-encounter
Memory
These cells are part of the innate immune system and kill infected cells by releasing toxic substances.
Natural killer cells
These cells, which are part of lymphoid cells, mature into plasma cells that secrete antibodies.
Adaptive immune system
These cells, which are part of lymphoid cells, mature into plasma cells that secrete antibodies.
B cells
Besides physical barriers like skin and mucus, this system includes chemical barriers such as tears and stomach acid.
Chemical barrier
This type of immunity involves B cells and the secretion of antibodies
Memory b cell
This type of T cell helps coordinate the immune response by releasing chemical signals called cytokines
Cd4 or cytotoxic t cells
This type of T cell can identify and destroy body cells that have been infected by a virus or have become cancerous what happen next
And then kill them
This type of T cell can identify and destroy body cells that have been infected by a virus or have become cancerous
Cytotoxic T cells
This system can tell a germ from a human cell, but not one type of germ from another.
Specificity
This system can recognize and respond to an almost infinite number of different antigens.
Specificity
These phagocytic cells are very good at "gobbling up" pathogens and are considered the best at presenting parts of pathogens to the adaptive immune system.
Macrophages or dendritic cell
This is the crucial role that macrophages and dendritic cells play in activating the adaptive immune system.
to recognize it immediately and mount a much faster, stronger, and more targeted response
This is the crucial role that macrophages and dendritic cells play in activating the adaptive immune system.
