How do the immune and lymphatic systems work with eachother?
The lymphatic system provides the pathways for immune cells to travel and interact, while the immune system utilizes these pathways to identify and respond to pathogens. Their reliance on one another is crucial for maintaining a robust and effective defense against infections.
What are the 5 main types of antibiotics?
IgG, IgA, IgM, IgE and IgD
What is the function of IgA?
Makes up majority of antibodies in serum
Only antibody that can cross placenta from mother to fetus
Functions in opsonization, neutralization and complement fixation
What is the function of IgA?
Found in secretions like breast milk and saliva
Functions in neutralization and aggultination
What is the function of IgM?
Functions in complement fixation
What is the function of IgE?
Binds mast cells and basophils and triggers their degranulation, facilitating inflammation, particularly in the immune response
What is the function of IgD?
Found on the surface of b cells
Has a role in B cell sensitization and activation
What is the second line of defense?
Responses of cells and proteins that make up innate immunity
What is the third line of defense?
Responses of cells and proteins of adaptive immunity
Innate immunity is _____
nonspecific
How fast is the response in innate immunity?
Dominant response to pathogens for the first 12 hours after exposure
What is the difference in time between adaptive and innate immunity?
AI responds slower than II because one must be exposed to specific antigen for response to be initiated
How long does it take for acquired immunity to mount response?
3-5 days
Describe innate immunity
Non-specific, immediate response, providing first-line defense through physical barriers, immune cells, and proteins.
Describe adaptive immunity
Specific, delayed response that develops over time, involving B cells and T cells, providing long-lasting immunity and memory for future exposures to the same pathogens.
