Chapter 16
The body's ability to resist pathogens and/or viruses
What is immunity?
This type of immunity is developed after exposure to an antigen
What is adaptive/acquired immunity?
Receiving pre-made antibodies, such as antivenom, is an example of this type of immunity
What is artificial passive immunity?
Where Hepatitis B virus replicate
What is hepatocytes?
This microbial community found on the skin and in various body parts competes with pathogens for nutrients and space
What is normal microbiota?
This response is mediated by T-cells
What is cell-mediated immunity?
This molecule is recognized by the immune system and can trigger an immune response
What is antigen?
This disorder is caused by Zika virus
What is microcephaly?
This enzyme, found in tears and saliva, breaks down bacterial cell walls
What is lysozyme?
This systemic increase in body temperature can inhibit pathogen growth and boost immune responses
What is fever?
These cells produce antibodies during humoral immunity
What are B-cells?
This common disease is caused by Streptococcus pyogenes
What is strep throat?
This process involves engulfing and digesting pathogens by immune cells like macrophages
What is phagocytosis?
This signaling protein's mechanism interferes with viral replication in infected and neighboring cells
What is interferon?
This class of antibody is most abundant in the blood and provides long-term immunity
What is IgG?
This causes intestinal problems
What is Clostridium difficile?
This system consists of proteins that enhance phagocytosis, inflammation, and pathogen lysis
What is the complement system?
These T cells directly kill infected or cancerous cells
What are cytotoxic T-cells/CD8+?
This antibody class is found in secretions such as saliva and breast milk, providing localized mucosal immunity
What is IgA?
This is the leading virus caused by wild animals
What is rabies?
